There is no rhipidion. The siphon is short, and similarly 

 situated to that of Spinax, but, instead of possessing thick walls, 

 its walls are remarkably thin.

 ECHINORHINUS SPINOSUS 



The spiny or bramble shark 



This species can only be, at present, described from a specimen 

 taken at Nice, which though 85 cm. in length is immature. 

 Figure 8 does no more than indicate a general resemblance to 

 Centrophorus, the absence of spines and the presence of a similar 

 siphon.
