 Acunthozone hystrix, Boeck, Forhandl. Vidensk. Selsk. p. 184 (1870). 



Hah. Carl Island and Cape Torell, in 12-18 fathoms. 



This species has been referred by Boeck to the Oniscus cuspidattis 

 of Lepechin (Acta Acad. Sci. Petrop. p. 249, pi. viii. fig. 3, 1780) ; 

 but the species figured by that author diifers in having vertically 

 projecting spines upon only the first four segments of the pereion. 

 The species figured by Buchholz (Zweite deutsche Nordpolarf. 

 Zool. Crust, p. 362, pi. xi.) as Acanthozone hystrix diff'ers from that 

 figured by Owen in the more numerous and closely placed spines 

 upon the posterior margins of the basa of the pereiopoda, and in 

 the form of the rostrum, and is, I think, distinct. 



The name Acanthozone has been substituted by Boeck for Acan- 

 thosoma, the latter name being preoccupied in entomology.
