The body as it approached the tail was compressed into a 
sharp ridge above and below. The pectoral flipper measured 
in its greatest length (from its tip to its anterior insertion) 
one foot seven inches, the eye was one and one-eighth 
inches long; the ear-hole, owing to the condition of the 
skin, could not be distinguished; the horns of the blower 
were pointed forward. The whole skin was smooth, and 
was entirely black, except on the underside, which was 
white from the chin to beyond the vent. In a younger 
and smaller specimen, retaining a portion of the skin, and 
which without the head measured six feet in length, there 
was much more white, which extended to and over part of 
the tail. The abortive hinder limbs in this example. 
consisted of a right and a left bone lying in the long axis 
of the body near the vent, and about twenty-seven inches 
from the cleft of the tail. They were about two inches 
and three-eighths long, and a quarter of an inch broad, 
somewhat curved upwards, flattened forwards, and rounded 
and thickened behind, where they nearly met.
