Under the name Ommastrephes Sloanii, J. E. Gray in 1849 pub- 

 lished the description of a species of squid from New Zealand belong- 

 ing to the typical group of the genus and having probable relationship 

 with 0. sagittatus. 11 Subsequently Steenstrup (1880) erected a new 

 species of his genus Todarodes ( = Ommastrephes s. s.) for the recep- 

 tion of an apparently very similar cephalopod in the Copenhagen 

 Museum from Hakodate, his description being supplemented by 

 Hoyle with further interesting notes in the Challenger Report (1886) 

 and a very excellent series of figures which fix the identity of the 



17 " 



Ommastrephes Sloanii. 



"Body cylindrical, rather tapering behind. Fin rhombic, rather more than 



one-third the length of the body. Sessile arms compressed; cups equal, oblique, 



in two rows; rings black, higher side with regular acute teeth, lower smooth; 



hird pair acutely finned, with a narrow, rayed, membrane on the inner edge of 



the ventral side. Tentacular arms slightly keeled externally, base half-naked; 



cups of lower pari small, in two rows, of middle four rows, "the seventh pair of 



central series largest ; rings with distant teeth all round; of the lateral series 



. longly peduncled, and very oblique; of the apical portion small, in three 



or four rows, the smallest one nearly sessile." (Gray, 1S49, p. 61.)
