    this is not sharply defined. Skull broad, low (depth of braincase only about half mastoid breadth), entire dorsal profile nearly straight, zygo- matic arches so widely expanded and postorbital region so much narrowed that distance from point of greatest narrowing to zygoma is greater than postorbital constriction; rostrum so shortened that posterior border of narial opening approaches level of anterior zygomatic root, and distance from orbit to gnathion is much less than half length of braincase; auditory bulla flattened, with conspicuous meatal tube; paroccipital process low and ridgelike but distinct from bulla. Teeth 36 (i. 3/3, c. 1/1, pm. 4/3, m. 1/2); large as compared with width of rostrum and palate (greatest transverse diameter of upper carnassial equal to half distance between carnassials); all of the small premolars opposed and capable of trenchant action with those of opposite jaw; upper carnassial with crown triangular in outline, the outer side occupied by a moderately high cutting edge formed by 2 cusps and a connecting ridge, the inner side (about half total crown area) by a flat crushing surface; upper molar rhombic in outline, its crown area about equal to that of carnassial (usually somewhat smaller), its greatest diame- ter transverse to axis of toothrow, 4 primitive cusps present; lower car- nassial with 3 anterior cusps well developed, subequal, posterior heel slightly larger than anterior triangle. External form highly modified for aquatic life, body long and of approximately same width as neck and head, tail long, very muscular, broad at base, tapering distally, legs short, feet broad, toes webbed, short-clawed; fur soft, dense and impervious to water. Nearly cosmopolitan; absent only from the Antarctic and high Arctic regions, Madagascar, Australia and Pacific Islands. #499 Lntra annectens Forsyth Major, 1897, Zool.
