longest not equalling the longest soft rays of the same fin. The origin of the first spine is below the first ray of the soft dorsal. There are three long and one short interneural bones in front of the dorsal fin. The origin of the ventral is below the third (or fourth) dorsal spine. The vertebræ have two fossa on each side, separated by a ridge. The jaws are edentulous. The scales are small and the specimens very well preserved.

In the largest specimen, I count, in a vertical line drawn from the first dorsal soft ray to the middle of the abdominal line, fifteen longitudinal rows of scales above and twenty-five below the vertebral column. On the opercular flap of a smaller, the typical specimen, I count nine vertical and fourteen transverse rows of scales.

The lateral line is visible in the largest specimen. It extends parallel to the dorsal border, marking at its greatest convexity less than onethird the distance from the vertebral column to the dorsal outline. It disappears behind the vertebral column below the seventh soft dorsal ray, and does not reappear.

This fish came from a deposit of the Green River Shales on Bear River, Wyoming.

PRISCACARA PEALEI, sp. nov.

Outline elliptic, with the extremities contracting equally or symmetrically to the head and tail. Depth at ventral fins entering length (with caudal fin) 2.60 times. Mouth rather small; length of head entering total length 3.8 times. Short conic teeth en brosse. Preorbital and preopercular bones finely serrated on their free margins. Vertebræ : D. 7; C.14. Radii: D. X-14; A. III-11; V. I. 5 or 6. The dorsal spines are rather slender; the anal spines are stouter, but shorter; the ventral spine is weak and slender. The ventral fin when appressed against the belly fails to reach the anal fin by a space a little greater than the length of the ventral spine; its origin is beneath the third dorsal spine. The scales are difficult to observe on the specimens, but there are not less than 15 to 17 longitudinal "ows along the abdomen in front of the anal fiu.

This species is similar in size and proportions to the Priscacara liops, but differs in having constantly but seven dorsal or abdominal vertebræ, while that species presents nine. I have not observed any serratures on the preoperculum of the P. liops, but the typical specimens are imperfect in that region, although good impressions of it remain on the matrix.

Two complete specimens present all the characters of this species, while in two others all the more important ones can be seen. Two additional specimens may be referred to it with the greatest probability. Some of these were obtained by Dr. A. C. Peale, in charge of one of the parties under Dr. F. V. Hayden, from the shales of the Green River formation of Wyoming. The species is dedicated to Dr. Peale, in recognition of his services to geological science.

PRISCACARA CLIVOSA, 8p. nov.

The species of Priscacara are referrible to two sections. In the first, the ventral spine is very strong, and there are but ten or eleven soft dorsal radii: here belong P. serrata, P. cypha, and P. oxyprion. In the second, the first ventral spine is weak and slender, and there are thirteen or fourteen radii of the second dorsal fin: in this division belong P. liops, P. pealei, and P. clivosa.

In the last-named fish, there are eight dorsal and fourteen caudal vertebræ. Radii: D. X—13; A. III-11. The ventral fin appressed, nearly reaches the base of the anal, a point in which it differs materially from the two allied species. Another characteristic is the form of the profile, which resembles that of some of the species of Geophagus. This descends steeply from a point just anterior to the base of the dorsal fin, giving an obliquity to that part of the outline and an inferior position to the mouth. The vertebral column is more arched anteriorly, appropriately to the prominence of the anterior dorsal region. The depth at the base of the first dorsal fin enters the total length (with caudal fin) 2.6 times, and the length of the head 3.6 times in the same.

The preopercular border is not visible in the only specimen of this species known to me. The operculum is scaly. There are 11-13 rows of scales on a line from the vertebral column to the abdominal border. I note here that further examination shows that there are from 20 to 25 longitudinal rows of scales on the side of the abdomen of P. serrata, but the number is not exactly determinable, owing to the condition of the specimens.

DAPEDOGLOSSUS ÆQUIPINNIS, sp. nov.

Two specimens present the principal character of this species, viz, the equality in number of rays in the dorsal and anal fins and the near equality in their size. The radii are in one, D. 23; A. 22: in the other, D. 22; A. 22. In D. testis, the formula is D. II-18; A. II-26. The vertebræ in one of the specimens of D. æquipinnis number, D. 19; C. 27: while in D. testis there are, D. 18; C. 24-25. (The number, 21 dorsal, originally given, must be corrected, as based on an imperfect specimen.) In D. æquipinnis, the first pectoral ray is not so largely developed as in D. testis, not being of unusual size. The hyoid apparatus and vomer are closely studded with teeth, as required by the generic character.

The specimens described are much smaller than those of the D. testis yet known, but No. 1 is probably young. This fact will not account for the peculiarity of the radial formula, etc.

I add here that there are two vertebræ included within the caudal fin in Dapedoglossus.

ART. III.-DESCRIPTIONS OF NEW TINEINA FROM TEXAS, AND

OTHERS FROM MORE NORTHERN LOCALITIES.

Very distinct from plumifrontella, popeanella, and arcanella Clem., and from agrotipenella and mortipenella Grote, nor can I recognize it at all in either Scardina or Bombycina as described by Zeller.

Palpi overarching the thorax; dark brown on the outward, luteousbrown on the inner surfaces. Antennæ compressed, straw-yellow; thorax dark gray-brown; fore wings brown, tinged with grayish-yellow; the usual spot at the end of the disk indistinct; the other spots common to the wings of the other species I cannot find in this. One of them may be represented by an indistinct blackish line beneath the middle of the fold. Hind wings and abdomen fuscous-gray, like the thorax, and a little darker or rather less yellowish than the fore wings. Under surface of both wings grayish-fuscous. Smaller than any specimens that I have seen of the other species, having an alar expansion of only nine lines. Bosque County, Texas.

T.! 7-STRIGELLA, n. sp.

TINEA.

Vertex white: basal joint of antennæ white on the upper, brown on the lower surface; stalk of antennæ black, with a white line along each side. Thorax and basal half of fore wings blackish-brown, the apical half having its costal half blackish-brown and its dorsal half white, the costal brown of the apical half being separated from the basal brown half by a white costal streak, which extends into the dorso-apical white part; beyond this costal white streak are five others, which likewise extend across the costo-apical brown to the dorso-apical white part of the wing, thus dividing it into a number of large spots; the first of these five streaks is oblique, the others perpendicular to the costal margin, and the space or brown spot between the second and third is larger than that between the others. Dorsal cilia brown, with numerous narrow white streaks running up through them from the dorsal white margin. In the basal half of the wing, there is a narrow white line extending along the fold, and an oblique white costal streak which almost reaches the fold. Face and palpi grayish fuscous. Under surface of
