elevated crests at each side of the snout in the bones of the 
upper jaw, it does not seem possible to unite this species with 
Hyperoodon, the shape of the head being exactly that of Ziphius. 
However, Ziphius (at least in the male) has two large teeth 
visible in the middle of the lower jaw; and as the specimen 
examined by me is also a male and has not these teeth, but wider 
ones, as in Hyperoodon, at the tip of the mandible, I am obliged 
to make a new genus for the animal here described. In dis- 
secting it the other day I examined all its internal structure 
and made drawings of the principal parts, in order to describe 
its organization afterwards in the Annals of our Museum. I give 
here a preliminary description from the examination made. 
The tongue is flat, of elliptic shape, and attached to the man- 
dible, having no free motion; there are 26 papille, placed in two 
rows on the back of the tongue. The pharynx has a rather small 
opening inclined backwards where it joins the larynx, which has 
an epiglottis much prolonged above, like a curved cone, which 
enters the posterior aperture of the nose. The trachea is rather 
short, 26 centim. long and 8 broad, and has a third bronchus on 
the right side, smaller, and placed more behind, before its final 
division into the two regular bronchi. 
There are three principal parts in the lungs—one on the left 
side of the body, and two, very unequal, on the right. The heart 
is tolerably large, but broader and flatter than in the terrestrial 
Mammalia. The internal structure is not different from the 
general type, but the distribution of the nutritive veins on the 
whole surface is very remarkable. There is a single opening 
of the nutritive vein in the right auricle, whence issues a large 
vein which descends in the lower longitudinal furrow as far as 
the tip of the heart, forming there a rather broad sac, from which 
issues, on the other side, another vein, ascending in the upper 
longitudinal furrow to the base of the ventricle. 
As to the digestive viscera, the cesophagus is internally covered 
with many folds; these folds descend into the first stomach, 
which is very large, of a remarkable sinuous shape, and in two 
unequal parts, of which the second part is the smallest and of 
a coarser and more muscular texture. Behind the first stomach 
there are seven others, of which the last is the largest, larger 
even than the first; the other six are very small, particularly 
the second, third, sixth, and seventh; the eighth is 34 centim. 
long, and the first 29 centim. The duodenum is very narrow, 
hardly 2°5 centim. wide, and the ilium very long, measuring 
17°5 metres. Its interior surface is covered with many folds, 
which form small bags at the sides. The colon is of twice the 
width, but much shorter, hardly 2 metres long; its internal 
surface has not so many folds and bags as the duodenum and
