. Catalogue of seals and whales in the British Museum . Seals (Animals); Whales. 18. Monaclius albiventer. Skull. From Cuvier, Oss. Foss. Muzzle rather elongate, broad, hairy, with a slight groove between the nostrils; whiskers small, quite smooth, flat, tapering. Pore feet short; fingers gradually shorter to the inner one; claws 5, flat, truncate. Hind feet hairy between the toes; claws very small; hair short, adpressed, with very little or no under-fur. SkuU depressed; i nose rather depressed, rather elongate, longer than the length of the zygomatic arch; palate ang-ularly notched behind. Cutting-teeth -i, large, notched within, the middle upper much smaller, placed behind the intermediate ones. Canines large, conical, sharp-edged. Grinders |i|, large, crowded, placed obliquely with regard to the central pala- tine line; crown large, conical, with several small conic rhombic tubercles. Lower jaw angulated in front below, with diverging: branches, the lower edge of the branches rounded, simple. The! grinders, except the two first in both jaws, are implanted by two roots; their crown is short, compressed, conical, with a cingOlum! strongly developed on their inner side, and developing a small ante- rior and posterior accessory cusp; the upper jaw is much less deep than in Halichoerus.; the canines are relatively large, and the nassd ! bones are much shorter. The feet, palate, and teeth resemble those of the genus Gallo- cephalus (O. communis), but the grinders are larger and less deeply lobed; and it has the smooth whiskers of the restricted genus Phoea (P. harlata). It differs from the latter genus in the depressed form of the skuU, the large tubercular grinders, and the angular termina- tion to the palate. As the other subtropical Seal, PJioca tropicalis (Gray, Cat. Seals, B. M. 28), from Jamaica, described froni an imperfect skin without a skiill, has similar spiaU smooth whiskers, it may very probably,' when its skull has,,been examined, be found to belong to th
