350 DESCRIPTION OF A SQUALUS. 



gantic species, it is easy to perceive the relations of 

 its form to other species which attain to an equal 

 magnitude, such as the S. Gunnerianus, S. Houiian- 

 us and 8. Peregrinus. But it is with the latter and 

 particularly with the individual captured on the coast 

 of Normandy that our species is most closely allied. 

 It resembles it in the form and number of the fins and 

 the vast openings of the branchia ; but the form of 

 its teeth are totally different, those of the S. Pelegri- 

 nus being conic, whilst those of our species are more 

 compressed than conic. I, therefore, propose to dis- 

 tinguish it by the following name and characters : 



SQUALUS *ELEPHAS. 



Teeth very small, numerous, curved, bicanaliculate, 

 bifid, in the middle of the series compressed, at the 

 extremities of the series subconic, pointed ; spiracles 

 very small; branchial openings very large, the ante- 

 rior one originating on the upper part of the neck ; 

 body very large, lead colour, darker on the back and 

 paler on the belly ; second dorsal filmost equal in size 

 to the anal, and placed anterior to it 5 tail long, with 

 a carina on each side.
