tliis is not the case is proved by the fact that the processes 

 from the peduncles of the cups go alternately to the web of 

 the two sides. On the distal parts of the arms where the cups 

 gradually become smaller, both series are plainly visible. The 

 »horny» rings of the brachial cups are armed all round with 

 sharply pointed teeth (about 24), those of the distal (broad) side 

 being much stronger (especially every second one and still more 

 so every fourth one) than the others. The specimen being pro- 

 bably a female, no hectocotylisation can be observed. The buccal 

 membrane has 7 points. The dorsal point is on its distal side 

 attached by a double connection to both dorsal arms, the six 

 others each to one arm. The outer lips are sraooth, rather 

 thin; the inner lips are folded and papillous. 



The tentacles, when extended, reach to the posterior end 

 of the body. The sucker-bearing area of the club is narrow. The 

 cups are arranged in 4 series, but those of the two outer rows 

 are very much reduced in size, so that they seem to be only 

 a kind of pedunculate appendices to the thick and fleshy basal 

 parts of their own peduncles, from which, on either side of a 

 protective membrane is suspended the club, in the same fashion 

 as on the arms. The cups of the two median series are, on the 

 other hand, very much enlarged, especially the middle ones, so 

 that each club carries 18 large suckers (occupying about 65 

 mm. of the club). The distal part of the club is very much 

 compressed and webbed so that it resembles a fin in shape. 

 This part (about 30 mm. in length) bears diminutive suckers 

 on long slender peduncles. Although these tiny suckers are 

 very densely crowded together, it is easy to see that they are 

 arranged in four series. The large tentacular suckers have their 

 horny rings armed with 4 large teeth disposed in a cross. 

 Between each of these, on the broader side of the ring, there are 

 4 teeth, and on the narrower, 5 or 6; thus about 23 teeth in all. 

 Proximally just beneath the club we find on the right tentacle 

 a system of 4 smooth ringed suckers and 3 pulvilli, on the left 

 the corresponding 4 pulvilli and 3 smooth-ringed cups, which
