''Teeth of the upper jaw absent, or reduced to a rudimentary 

 pair in front ; in the lower jaw 9 to 1 2 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- 

 tebrae: C. 7, D. 13 or 14, L. and C. 30; total, 50 or 51. All the cer- 

 vical vertebras 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 maxillae, 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 remain still in their alveoli; some have been replaced by others; they 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^/2 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."
