DENTICULATED SHARK. 351 



^cute angle : above and below was a transverse 

 fossule or dent : the tail was of the form of a cres- 

 cent, but the horns of unequal length ; the upper* 

 being thirteen inches, the lower ten : the whole 

 fish was of a leaden colour, and the skin compara- 

 tively smooth, being far less rough than in most 

 of the genus. This and the preceding fish seem 

 very nearly allied, and perhaps may only constitute 

 sexual differences of the same species. 



DENTICULATED SHARK. 



Squalus Denticulatus. S. griseus, supra maculis niagnis incequA' 



libus rujisj dorso elevato tuberculis denticulato. 

 Grey Shark;, marked above with large unequal rufous spots, 



with elevated back denticulated by tubercles. 

 Squale dentele. Cepede. 



Colour greyish or pale ash-brown, marked over 

 the Vv^hole upper part with large, irregular, rufous 

 spots : back much elevated, and appearing denti- 

 culated by a row of small tubercles, running from 

 between the eyes to the first dorsal fin : all the fins, 

 except the caudal, tipped with brown : first dorsal 

 fin placed beyond the middle of the back : tail 

 bilobate, the upper lobe longer than the lower, and 

 indented by a partial division : teeth triangular : 

 size not mentioned : described by Cepede from a 

 dried specimen in the Prince of Grangers Museum. 



* In the British Zoology the upper lobe is said to be ten, and 

 the lower thirteen inches long ; but it is clear from the plate, 

 engraved from Mr. Davies's drawing, that this is an error.
