144 .J. E. Verrill — Molhisca of the New England Coast. 



alteiTiating with the median hooks, and with proximal and terminal 

 groups of smaller suckers. Color pale, with numerous small dark 

 brown chromatophoi'es above, larger and more crowded on the head 

 and on the bases of the arms ; lower side with several larger, round, 

 symmetrically placed, puiplish brown spots, and wnth minute ones 

 between them. 



Length of mantle, 1.5"""; diameter of body, 7""" ; length of tin, 

 11"""; breadth across fins, 18"""; breadth of head, 7'""'; diameter of 

 eye, 4-5'""^; length of dorsal arms, 13"^"; length of second pair, 

 j4mnj. of third pair, 14"""; of tentacular arms, 25"^"^ ; of ventral arms, 

 10""". Probably this specimen is immature. 



The specimen described from the Blake collection is still younger, 

 but the general figure referred to is from the original specimen, 

 described above.

Eledonella Verrill, geu. nov. 



General appearance similar to that of certain small species of Octo- 

 pus and Eledone. Body oblong-ovate, soft and saccular, wnthout 

 fins. Mantle extending forward as far as the eyes. Gill-opening 

 very wide, extending upward on the sides as far as the dorsal margin 

 of the eyes, which may be partially concealed by the edge of the 

 mantle. Arms slender, the upper ones shortest, the third pair largest. 

 Suckers in a single row. Third arm of the right side hectocolylized 

 by having the terminal half thickened and somewhat shortened, and 

 bearing on its distal half a few very large urceolate suckers, very 

 much larger than any of the others, and quite different in form. 

 Interbrachial membrane short. Eyes well developed, nearly covered 

 by the skin ; a mucus-pore close to the anterior ventral border of the 

 orbit. Siphon moderately developed, free only near the tip ; pos- 

 teriorly the basal part of the siphon extends into two commissual 

 muscular bands on each side ; the ventral one runs far back, while 

 the lateral curves upward to join the mantle. There is a large median 

 ventral commissure joining the mantle to the visceral mass; thus the 

 gill-chamber is divided into right and loft com])artments, each of 

 which is sub-divided into a superior and inferior portion. No special 

 cartilages could be seen on tlie mantle, nor on the siphon. Repro- 

 ductive organs large, highly colored with large orange chromato- 

 phores.
