378 REPORT OF COMMISSIONER OF FISH AND FISHERIES. [168] 



ered with small, conical, scattered, whitish papillae, which are also found 

 on the upper and lateral surfaces of the head and the bases of the arms; 

 those around the eyes largest; one on the mantle, in the median line, 

 near the front edge, is often elongated. Front border of mantle sinu- 

 ous, slightly advancing in the middle, above. Fins moderately large, 

 nearly semi-circular, attached from the posterior end for about four-fifths 

 the whole length, the front end having a small, rounded, free lobe. The 

 distance from the posterior junction of the fins to the end of the body is 

 less than that from the anterior junction to the edge of the mantle, the 

 center of the fin being at about the middle of the body. Siphon elon- 

 gated, conical, with a small opening. Head depressed, more than half 

 the length of the body. Eyes large, the lower eyelid prominent, but 

 not much thickened. Sessile arms short, united at their bases by a short 

 web, which is absent between the ventral arms; the dorsals are short- 

 est; the third pair the longest and largest; the second pair and ventrals 

 about equal in length. Suckers (PI. XXXVI, fig. 5, a), numerous, sub- 

 globular, not very small, the margin bordered with several rows of 

 minute scales; near the base of the arms they are biserial, there being 

 usually four to six thus arranged in each row; then, along the rest of 

 the length of the arms, they become more crowded and form about four 

 rows, those in the two middle rows alternating with those in the mar- 

 ginal rows ; toward the tip they become very small and crowded, espe- 

 cially on the dorsal and ventral arms. The number of suckers varies 

 with age, but on one of the original specimens they were as follows: on 

 each dorsal arm, sixty; on one of the second pair, fifty-five; of third 

 pair, fifty -three; of ventral, sixty-five. In this specimen ($), the third 

 arm of the right side and the ventral arm of the left side were abruptly 

 terminated (accidentally), while the others were tapered to acute points. 



The tentacular arms, in preserved specimens, will extend back to the 

 posterior end of the body; the naked portion is smooth, somewhat 

 triquetral, with the outer side convex and the angles rounded; terminal 

 portion widening, rather abruptly, long ovate-lanceolate, curved and 

 gradually tapered to the tip; the sucker- bearing portion is bordered by 

 a wide membrane on the upper, and a narrow one on the lower margin ; 

 the suckers (Plate XXXVI, fig. 5, b, c) are very small, sub-globular, 

 crowded in about eight to ten rows in the widest portion. 



The males (PI. XXXVI, fig. 6) differ from the females in the relatively 

 greater size of the suckers on the middle of the lateral and ventral arms, 

 those toward the tips becoming abruptly smaller, while in the female 

 they decrease more gradually. 



Color, pinkish, thickly spotted with purplish brown above, paler and 

 more sparsely spotted beneath and on the outside of the long arms; the 

 inner surfaces of the arms and front edge of the mantle are pale. 



Length, of a medium-sized specimen, from bases of the arms to the 

 posterior end of the body, 40 mm ; of body, 25; of head, 15; breadth of 

 body, 17; of head, 17; length of fins, 15; of insertion, 11; breadth of
