During a superficial examination of the viscera no especial peculiari- 

 ties were noticed except so far as the penis was concerned. This organ, 

 instead of having the tapering form common among the dolphins, is' 

 Ungulate, strongly flattened, and obtusely pointed. The orifice is in- 

 ferior. 



The testicles were of immense size, showing that the animal was capt- 

 ured in the rutting season. They measured 30''™ in length. 



The intestine measured 60 feet in length, and is, therefore, short 

 compared with Tnrsiops tursio, Delphinus delphis, and some other 

 species. The stomach, which was of the normal form, was filled with 

 the bones of the scuppaug [Stenotomus) and a species of sea-robin 

 {Prionotus). 



The animal had met with a severe accident in the course of its career, 

 the fifty fourth to the fifty-seventh caudal vertebrae being broken and 

 soldered together. The margin of the caudal peduncle above these ver- 

 tebrae was broken by deep grooves, and a swelling of considerable size 

 was visible on its side.
