Page 197 - M* with large and broad heel; MT with strongly developed cusplet on inner side of saddle. Remarks. — Ursus shirasi is a very large member of the brown bear group. Whether it is always black, like the type specimen, is not known. But of all the American bears its skull is the most striking and distinctive. The short broad frontal shield rising on each side into huge postorbital processes, which arch broadly over the orbits, serve to distinguish it at a glance from all other species, rendering close...
Page 183 - ... Yellowstone Rivers, eastern Montana): Of generalized grizzly type; large and rather massive; vault of cranium rather flat; braincase rather broad; frontal shield of moderate breadth, slightly convex, slightly depressed or sulcate between orbits, elongate-lyrate posteriorly; postorbital processes weak and slightly decurved; sagittal crest not yet reaching fronto-parietal suture; muzzle moderate or rather short; zygomata moderately spreading and rather angular; palate rather narrow. Teeth large...
Page 166 - Its antennse which are rather longer than the head and composed of eight nearly equal joints, have the third joint of a white color. The abdomen is concave on its upper side, and is furnished with a conical tube at its tip which has a few bristles projecting from its apex. The wings when folded are linear, silvery-white, and as long as the abdomen; they are pressed closely upon the back, spreading asunder at their bases, and appear...
Page 188 - Adult male (type) compared with adult male caUfornicua (from coast region south of San Francisco Bay) : The differences are marked in the skull and striking in the teeth. In klamathensis the vault of the cranium is lower posteriorly and higher anteriorly ; the frontal shield flatter laterally; the rostrum shorter; the base of the cranium (occipito-sphenoid) decidedly shorter. The last upper and middle lower molars are widely different, the heel of M> in...
Page 190 - M^- decidedly smaller (both shorter and narrower) ; lower series of teeth smaller, MT and M^ particularly smaller, much narrower and less massive; heel of last upper molar less broad than in caUfornicus.
Page 166 - ... conical tube at its tip which has a few bristles projecting from its apex. The wings when folded are linear, silvery-white, and as long as the abdomen; they are pressed closely upon the back, spreading asunder at their bases, and appear like an elongated white Y-shaped mark. Viewed from above, the head is of a square form, longer than wide. The first segment of the thorax is well separated from the second, is broadest at its base, and gradually tapers to its anterior end, where it is as wide...
Page 178 - ... narrow, low, flat, or slightly concave, acutely rather short pointed posteriorly, the point entering sagittal crest about onethird the distance from fronto-parietal suture to postorbital process; sagittal crest moderate, reaching more than halfway from occiput to postorbital processes; postorbital processes rather thick, outstanding; fronto-nasal region elevated (not dished); rostrum high and sloping gently upward in plane of frontals; lachrymal opening within orbit; palate long and narrow; postpalatal...
Page 165 - August several apples were noticed upen the trees which were small, withered, and ready to fall, yet without any of those worms in them which occasion the destruction of so much fruit at this season of the year. On searching for the cause of this withering of these apples we found a small cavity or little hollow at the tip end, commonly close beside the relics of the flower. This cavity had the appearance of having been gnawed; it was about the size of a pea, and its surface of a black color. Several...
Page 121 - A. A new Accipiter from Porto Rico with notes on the allied forms of Cuba and San Domingo.
Page 195 - ... apparently normal. Skull long, narrow, and high, but not arched; fronto-nasal region high and very narrow — strongly pinched in. Color. — Skin of head of male killed on Pine Valley Mountain, southwest Utah (obtained from forest ranger, September 24, 1907, by Clarence Birdseye; original No. 989) : Muzzle pale brown; face and throat, except pale lip edgings and long hairs of median line of throat, dark brown, becoming grizzled posteriorly ; top of head very dark; grizzled posteriorly by brown-tipped...
