CEPHALOPODA. — BERRY 215 



Tentacles stout, fleshy, a trifle longer than the mantle, or a 

 little over half as long again as the ventral arms ; stalks rather 

 flattened dorso-ventrally so as to give them a somewhat 

 rectangular outline in cross section, while they are consider- 

 ably deeper than wide at the base, whence they taper to just 

 before the carpus, the latter region veiy slightly wider. 

 Tentacle club again narrower than the carpus, slender, and 

 tapering rapidly to the extremity as in previously described 

 species of the genus. Carpus with a compact fixing apparatus 

 of 4-6 suckers and 4-5 pads occupying (as seen by a strongly 

 oblique lighting), a somewhat sharply delimited, flattened, 

 oval area on the oral face, and so crowded together within this 

 area that it is sometimes very difficult to distinguish the true 

 pads from certain (usually more irregular) roundish swellings 

 arising in connection with the bases of most of the suckers 

 <P1. Ix., figs. 1, 2). Club proper (PI. Ix., fig 2) with two 

 alternating series of hooks along its proximal four-fifths ; 

 ventral series comprising a small proximal hook succeeded by 

 five conspicuously larger, long, slender, strongly curved hooks, 

 the second and third the largest of the series, the remainder 

 gradually diminishing in size ; dorsal series comprising five 

 much smaller hooks of which the second is the largest, the 

 distal ones very gradually diminishing in size ; no suckers 

 proximal to the hooks in either series, or between the hooks 

 and the fixing apparatus, in any specimen examined, but two 

 of the four perfect tentacle clubs (PI. Ix., fig. 1) show a small 

 sucker similar to the suckers of the distal portion of the club 

 just distal to the hooks of the dorsal series and occupying a 

 position opposite the space between the two most distal hooks 

 of the ventral series, the presence or absence of this sucker 

 apparently depending respectively upon whether the first 

 hook of the dorsal or of the ventral series is the more proximal 

 in its position upon the club and relative to the first hook of 

 the opposite row, hence the said sucker no doubt is homologous 

 with the sixth hook of the ventral series. Distal seventh of 

 club occupied by four rows of small, closely-placed suckers, 

 coimting some 38-43 in all, which gradually diminish in size 

 toward the extremity, excej)t that a roughly defined circle of 

 some 5-6 suckers almost at the tips (usually followed by one 

 or two more minute suckers) are again somewhat larger than 

 those just preceding them.
