REPORT OF COMMISSIONER OF FISH AND FISHERIES. [168] 
ered with small, conical, scattered, whitish papilla, 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 (Pl. 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 (9), 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 (Pl. XX XVI, 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™™; of body, 25; of head, 15; breadth of 
body, 17; of head, 17; length of fins, 15; of insertion, 11; breadth of
