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

 pair in front; in the lower jaw 9 to 12 on each side, rather long, 

 slender, pointed and curved, with a coating of enamel. Upper sur- 

 face of cranium concave, with thick, raised posterior and lateral mar- 

 gins, massive and rounded at their anterior terminations above the 

 orbits. Upper edge of the methesmoid forming a prominent sinuous 

 ridge, constituting a kind of longitudinal septum to the base of the 

 great supra-cranial cavity. Rostrum not longer than the cranial por- 

 tion of the skull, broad at the base, and rapidly tapering to the apex. 

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

 cervical vertebrae united by their bodies and arches." (Flower.)

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 Cachelots, and 

 terminate abruptly by the very short and pointed maxillaries, there- 

 fore 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 have a considerable symphysis, 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 re- 

 placed 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."
