rows. Towards the proximal end of the club the suckers 

 stand in fewer rows. Sessile suckers extend in about four 

 scattered rows halfway down the internal face of the tentacle; 

 these are very minute and become very sparsely scattered as 

 they reach the middle of the tentacle. 



The cups of the suckers on the club are hemispherical and 

 the horny ring bears in its upper half fine pointed teeth. 



There is a well-developed buccal membrane with about 

 eight ill-defined angles.

This species, which is named after Dr. Alex. Bowman, 

 naturalist on board the ' Goldseeker,' is very close to the only 

 other species of the genus, B. heanii, Verrill. It is described 

 as new because it seems to offer several points of difference 

 and because it does not resemble at all closely VerrilPs figures 

 (Rep. U.S. Comm. Fish, for 1879 (1882), p. 424, pi. xlv. 

 ■figs. 3-3 h, pi. xlvi. figs. 2, 2 a). The great size of the eyes, 

 the pigmented cornea, the shape of the anterior margin of the 

 mantle, the peculiarities in the structure of the suckers and 

 of the tentacular club seem to warrant its separation from 

 Brachioteuthis heanii.

The body is flattened dorso-ventrally. It is oval in 

 outline, the sides curving in sharply at the posterior end, 

 where the terminal part of the pen runs out, fringed by tiie 

 small fins, which together form a broad ellipse. This terminal 

 portion is 3 mm. long by 2*7 mm. broad. The tip of the 

 pen extends a very little way beyond the tins. The length
