Dr. H. Burmeister on a new Cetacean. . 97 
ilium. There is no cecum, as is always the case in the true 
Cetaceans. 
No food of any kind was found in the intestines, only a 
mucous yellow fluid in the small intestine, and a fluid of a black 
colour, like pitch, in the large one. Probably the animal had 
fasted for a long time; and there is no doubt that the heavy 
storm from which Montevideo had suffered two days before had 
forced him to take refuge in the mouth of the Rio de la Plata. 
The liver is situated on the right side of the last stomach, 
covering it with its lower part, which is the smoother of the two 
into which it is divided. There is no gall-bladder, but a wide 
duct entering the duodenum by the side of the pancreatic 
duct. The pancreas is large and of regular construction, 
situated between the curvatures of the eight stomachs. The 
spleen is a thin mass, small, of triangular shape, behind the first 
stomach, and closely attached to its upper part. The kidneys 
are large, 40 centim. long, spindle-shaped, fastened to the centre 
of the belly above the other intestines, and composed of nume- 
rous divisions, of the shape and size of a large nut. The urinary 
channel is a metre, more or less, long; the bladder very large 
and of thick substance. 
The sexual organs are not perfected—proving, as does the 
soft and spongy texture of the bones, that the animal was still 
young. 
The body consists of a large mass of very dark, almost black, 
flesh, and over this, covering the whole surface, a layer of 
whitish fat, of 5 centim. thick. The skin is thin, closely united 
to the fat, and is composed of two layers, the inner one soft and 
black, the outer hard and grey. Over this skin extends a fine 
but hard and very smooth epidermis, which gives a shining 
appearance to the animal. It is said that the inner skin of the 
Anarnae (Hyperoodon) is considered a delicacy by the inhabi- 
tants of Greenland and Iceland, in the seas of which these 
animals abound. 
I cannot enter into a detailed description of the skeleton, 
since its preparation has not been concluded. I can only give 
afew general details of the shape of the skull and of the number 
of the vertebre and ribs. The skull is exactly similar to that in 
the genus Ziphius, and has not the smallest resemblance to that 
of Hyperoodon. ‘The upper part, with the opening of the nose, 
is much arched, and the right side is much larger than the 
left. The zygomatic bones are extremely thin, and are free 
behind, and the os petrosum is united to the skull very 
firmly. Of the seven vertebra of the neck, the first three are 
united in one piece, the others are free. There are ten dorsal 
vertebrae, with ten pairs of ribs, of which six are directly joined
