“Teeth of the upper jaw absent, or reduced to a rudimentary 
pair in front; in the lower jaw g to 12 on each side, rather long, slender, 
pointed, and curved, with a coating of enamel. Upper surface of 
cranium concave, with thick, raised posterior and lateral margins, 
massive and rounded at their anterior terminations above the orbits. 
Upper edge of the methesmoid forming a prominent sinous ridge, con- 
stituting a kind of longitudinal septum to the base of the great supra- 
cranial cavity. Rostrum not longer than the cranial portion of 
the skull, broad at the base, and rapidly tapering to the apex. Ver- 
tebre: C. 7, D. 13 or 14, L. and C. 30; total, 50 or 51. Aue 
vical vertebre united by their bodies and arches.’’ (Flower.)

fornia, possibly of Mexico, and Atlantic coast of North America. 
Genl. Char. Blainville’s description of a skull of this species in 
the Paris Museum, from an individual taken at the Cape of Good 
Hope, translated, is as follows: ‘‘Skull extremely wide and greatly 
elevated, having the frontal crests very high and consequently the 
nasal cavities very deep, something like those of the Cachalots, and 
terminate abruptly by the very short and pointed maxille, therefore 
the total length is barely an inch greater than the occipital length. 
The lower jaw has necessarily two branches approaching each other 
evenly, like a bellows, and a considerable symphsis, with a narrow 
extremity, but rounded termination. It is nearly certain that there 
are no teeth in the upper jaw, but the lower has 14 or 15 on each side, 
all of which are not in place, 5 only on the left side and 4 on the right 
remain still in their alveoli; some have been replaced by others; they 
are narrow, slender, conical, pointed, slightly curved interiorly, and 
6 to 8 lines in length. Length of lower jaw, 13 inches; distance 
between condyles, 12 inches. Length of skull, 14% inches. Another 
peculiarity of the skull is the inequality of the nasal cavities, the right 
being in nearly a rudimentary condition, and some twenty times 
smaller than the other.”
