DESCRIPTION OF A NEW GENUS AND SPECIES OF PEDICULATE FISHES (HALIEUTELLA LAPPA).

By G. BROWN GOODE AND TARLETON H. BEAN.

(Read March 8, 1884.)

HALIEUTELLA, new genus.

Body maltheiform, subcircular, depressed, its width equal to its length; covered with flaccid, inflatable skin. Spines feeble and less numerous than in Halieutœa. Head merged in body; forehead with a transverse bony ridge; no perceptible supraoral cavity; no tentacle. Mouth small, terminal; lower jaw slightly curved forward. Teeth in the jaws minute, cardiform; not discernible on palate, though possibly present. Carpus broad, slightly exserted. Pectoral fins remote from tail, obliquely placed, with membranes subvertical. Branchial aperture posterior to carpus, upon the disk, and not remote from its margin. Dorsal fin 5-rayed, inserted at junction of disk with caudal peduncle. Anal fin 4-rayed, originating at root of caudal peduncle.

Halieutella lappa, new species.

Disk subcircular, more than two-thirds as long as the body. Body covered with a loose, flaccid, inflatable skin, which so obscures its proportions that it is impossible to determine its exact height, but it is not nearly so much depressed as in the related genera. When the body is inflated the height and length of the disk are nearly equal. Spines rather feeble; about ten between snout and dorsal fin. About six strong spines, with conical bases and stellular tips on the outer margin of the disk on each side, the anterior of them being opposite the eye. In front of these spines on the discal margin, and between them and the snout, are several small, simple spines, pointing backward. Belly armed with spines similar to those on the back, but weaker. A stellate spine upon the tip of the snout, with two weaker, simple spines on each side. Nasal openings midway between eye and tip of snout. Mouth small, upon the margin of the disk. The upper jaw is shorter than the diameter of the eye. Teeth as described in the generic diagnosis. Dorsal fin inserted at posterior limit of disk, with five simple, articulated rays, its longest ray one-fifth as long as the disk. Anal fin with four simple, articulated rays, inserted directly beneath the fourth ray of the dorsal; its second, and longest, ray one-fourth as long as the disk. Caudal twice as long as anal and slightly longer than caudal peduncle, with nine simple, articulated rays. Carpus inserted at a distance from the snout equal to twice the length of the longest pectoral ray, which is slightly greater than the distance of posterior margin of carpus, at its junction with disk, from vent. Number of pectoral rays, 15. Ventral inserted at a point equidistant from the snout and the origin of the anal; length of its longest ray (the fourth) equal to one-half the distance of the anal fin from the snout. Number of ventral rays, 5. D. 5; A. 4; C. 9; P. 15; V. 5. A single specimen, 14 inches long, was dredged by the U. S. Fish Commission steamer Fish Hawk at station 1151, north latitude 39° 58′ 30′′, west longitude 70° 37′, in a depth of 125 fathoms. Color, yellowish white.

DESCRIPTIONS OF SOME NEW NORTH AMERICAN

BIRDS.

BY ROBERT RIDGWAY.

Read February 23, 1884, and published by permission of the Director of the U. S. National Museum.

1. Parus atricapillus turneri, new subspecies.

SUBSPECIFIC CHARACTERS.-Similar to P atricapillus septentrionalis, but still lighter in color, the gray of the upper parts very slightly, or not at all, tinged with brownish, the sides and flanks with little or no buff tinge.

: Wing, 2.70; tail, 2.65-2.90; tarsus, .65-.70. 9: Wing, 2.55; tail, 2.55. Hab. Alaska.

Type, No. 70,826, (in collection, U. S. National Museum,) St. Michael's, Alaska, May 1, 1876; L. M. Turner.

2. Psaltriparus minimus californicus, new subspecies

SUBSPECIFIC CHARACTERS.-Differing from true P. minimus in much lighter colors, especially on the lower parts, which are very pale brownish gray, or soiled brownish white, only slightly tinged purplish brown on the flanks. Hab. California, except northern coast district.

In "Birds of North America," (page 397), Professor Baird remarks that "there is quite an appreciable difference between specimens of this species from Washington Territory and California ; the latter are smaller, the under parts paler." He did not separate them, however, the scant material at his command evidently not warranting such a procedure. With numerous additional specimens, the differences are none the less striking, and, in my opinion, fully sufficient to justify their separation as well-defined geographical races.

It may be remarked that specimens from Marin County, just north of the Bay of San Francisco, are dark colored above like typical

P. minimus, but are light colored beneath as in californicus, being thus, as should be expected, intermediate; further north, along the humid, densely wooded coast, specimens probably approximate more closely to the typical form.

Types, Nos. 91,643, & ad., Baird, Shasta Co., California, May 27, 1883, Chas. W. Townsend; 71,935, 9 ad., Ft. Tejon, Cal., Aug. 7, 1875, H. W. Henshaw; 71,924, Walker's Basin, Cal., fall; 71,918, ad., same locality and collector, Nov. 10, 1875; 91,890, juv., Baird, Shasta Co., California, June 26, 1883, Chas. W. Townsend.

3. Colaptes mexicanus saturatior, new subspecies. SUBSPECIFIC CHARACTERS.-Similar to C. mexicanus, but much darker colored. Back, etc., rich, dark umber-brown, throat deep plumbeous-gray, and lower parts deep vinaceous-pink. Hab. Northwest coast, from the Columbia River to Sitka.

Types, Nos. 40,063, & ad., Neah Bay, Washington Territory, J. G. Swan; 13,516, 9 ad., Simiahmoo, Washington Territory, Dr. C. B. Kennerly.

4. Myiarchus mexicanus magister, new subspecies.

SUBSPECIFIC CHARACTERS.—Differing from typical M. mexicanus in much larger size, with proportionally longer and stronger bill. Wing, 4.05-4.40; tail, 4.10-4.60; culmen, 1.10-1.27; bill from nostril, .60-.82 (average about .70); tarsus, .88-.95 (average about .92). Hab. Western Mexico, north to southern Arizona.

Types, Nos. 86,005, & ad., Camp Lowell, Arizona, and 57.640, ad., Tehuantepec, Mexico.

In order to determine positively, if possible, the relationship of the larger Mexican Myiarchi, I sent recently to Dr. Sclater a series of specimens, asking him to compare them with Kaup's types of his Tyrannula mexicana and T. cooperi, which were supposed to be in the British Museum. His reply has just been received, and is, in substance, as follows:

"The original of Kaup's description [of T. mexicana] is not in

the British Museum, . . . . but in that of Darmstadt, whence I obtained the loan of it in 1871. I cannot do this again, but I have a specimen in my own collection which, on that occasion, I compared with Kaup's type and found to be similar, except as regards the abraded plumage of my specimen. This specimen certainly agrees best with the smaller or eastern race, . . . . that is with J cooperi of Baird, . . . . but is smaller in dimensions than Baird's type, and, therefore, much smaller than the large western form of the same species. . . . . What Tyrannula cooperi of Kaup was, it is now, as I believe, impossible to ascertain; because, if the specimen so described is in the British Museum, as Kaup affirms, it is not marked, and is, consequently, unrecognizable."

It will thus be seen that the large western race is unnamed, which is my excuse for providing it with a name as above.

5. Myiarchus lawrencei olivascens, new subspectes. SUBSPECIFIC CHARACTERS.-Differing from true M. lawrencei of Eastern Mexico, in very much paler colors: Pileum light hairbrown, instead of dark sooty brown; back light grayish olive, instead of dark brownish olive; remiges and rectrices edged with dull ochraceous-rufous, instead of rusty rufous. Wing, 2.90-3.253 tail, 3.00-3.25; culmen, .65-.70; width of bill at base, .30-35 ; tarsus, .7-.75. Hab. Western Mexico, north to southern Arizona; in winter, western and southern Mexico, and Yucatan.

Type, No. 57,655, & ad., Sta. Efigenia, Tehuantepec, Dec. 25, 1868; F. Sumichrast.

I have carefully examined the type of Musicara lawrenci Giraud, and find that it corresponds exactly with specimens from eastern Mexico, which are, without exception, (so far as the National Museum series are concerned,) much darker colored than those from western Mexico.

In Hist. N. Am. B. ii, p. 333), M. latorencei oatascens, was erroneously considered to be the true M. lawrence, the dark eastern race (true M. lawren, ei being referred to M. m ̧ricapillus Caban. The latter is similar, but still darker, having the pileum nearly black, (whence the name). It reaches its extreme develop
