sixth and seventh cervical vertebrae have only two rather short 

 processes on each side, the upper process being the most slender, 

 compressed, and bent down, and the lower ones conical, stronger, 

 compressed. The processes of the third vertebra are the thinnest, 

 and they gradually increase in thickness and strength to the 

 seventh or last. 



The specimen here described was mentioned in the papers of 

 the day as a Spermaceti Whale !

In the Museum of the Hull Literary and Philosophical Society 

 there is a very perfect skeleton of this species taken in the Humber, 

 which is 50 feet long. It has 64 vertebrae, as follows : cervical, 7 ; 

 thoracic, 16 ; lumbar and caudal, 41 ; and the arms or paddles are 

 6 feet .9 inches long. The ribs 16 pair, all simple. The baleen 

 is black. 



This specimen is said to have been eight years old, but on 

 what authority I cannot learn. 



I have to thank my friend Mr. Pearsall, the curator of the 

 above museum, for his kindness in sending me detailed drawings, 

 of the natural size, of the cervical vertebrae of this interesting 

 species.
