11. Ommastrephes eblance (Ball). 



Loligo eblance, Ball, Proc. Roy. Irish Acad. vol. i. p. 463. 

 Oiiimastrephes eblance, Forbes and Hanley, Hist. Brit. Moll. iv. p. 235, 

 pi. SSS. fig. 2; Steenstrup, Ommat. Blrcekspr. p. 97. 



Body proportionately short ; suckers confined to the clubs 

 of the tentacles, minute and four-ranked at their extremities ; 

 fins occupying three sevenths of length of body. The arms 

 bear remarkably large pedunculate suckers, two-ranked and 

 set well apart. 



These characters from Forbes and Hanley's description do 

 not accord with any other British species. The four-ranked 

 suckers of the tentacular clubs separate it from 0. Coindetii, 

 and the absence of suckers on the stems of the tentacular arms 

 distinguish it from 0. sagittatus. 



The localities given by Forbes and Hanley are Dublin 

 Bay [Warren and Ball) and Belfast (W. Thompson). 



Subgenus 2. Illex, Steenstrup. 



Distinguished from Ommastrephes (s. str.) by the absence 

 of all simple suckers and tubercles employed for mutual 

 cohesion on the tentacular clubs, and by the suckers of the 

 club being arranged at the extremity in eight rows. The 

 siphonal reception-groove is smooth at its commencement.

Additional localities. Firth of Forth {Edinburgh Mas., fide

Distribution. Mediterraneann (d 1 Orbigny &c), Naples (Zool. 

 Stat. !), West and South-west France (Fischer). 



A fine male in my collection from Naples shows that this 

 species has the right ventral arm hectocotylized. This arm 

 has its lower and outer margin, especially on the distal portion 

 of its length, thickened and widened out laterally, so that the 

 extremity is much broader than the corresponding part of the 

 left arm ; at about 1 inch from the extremity the suckers 

 entirely cease, and what were the peduncles of the outer row
