 on the back of the club.

Size large ; body stout, nearly round, swollen in the middle. Caudal 

 fin very small, sagittate. Head large, short. Eyes very large, oblong- 

 ovate, with well developed lids and anterior sinus. Sessile arms stout, 

 their suckers large, very oblique, with the edges of the horny rings strongly 

 serrate, especially on the outer margin. The margin has around it a free- 

 edged membrane, which closely surrounds the denticles when the sucker is 

 used, and allows a vacuum to be produced. Tentacular arms very long and 

 slender in extension, the proximal part of the club furnished with an 

 irregular group of small, smooth-rimmed suckers, intermingled with rounded 

 tubercles on each arm, the suckers on one arm corresponding with the 

 tubercles on the other, so that by them the two arms may be firmly attached 

 together without injury, and used in concert ; other similar suckers and 

 tubercles, doubtless for the same use, are distantly scattered along the slender 

 part of these arms, one sucker and one tubercle always occurring near 

 together. The internal shell is thin and very broad, expanding from the 

 anterior to the posterior end, with divergent ribs (Verrill). 

 A. verrilli, sp. nov. Pig. 1. 



Body short, stout and nearly round, dilated in the middle. 



Sessile arms unequal in size and length ; the first, second and fourth 

 pairs about same length as body and head together, third pair longer and 

 stouter ; all armed with similar suckers, but varying in number, the third 

 pair carrying more than either of the others. 



Tentacular arms, when extended, nearly three times the length of head 

 and body. 



Caudal fin obcordate, small dorsal ; from tip to front margin about one 

 third the length of the body ; terminating posteriorily in a blunt point.
