326 REPORT OF COMMISSIONER OF FISH AND "FISHERIES. [116] 



to have been wider, with the edges infolded, so as to form a sort of fur- 

 row on the outer side, but the supers are mostly gone, and it is too 

 much injured to be accurately described. Tentacular arms long, more 

 than twice the combined length of the head and body, slender, round, 

 gradually tapering to the tip, like a whip-lash, the distal half of their 

 length covered with very numerous, crowded, minute, pediceled suckers 

 (fig. 2 b). which cover nearly the entire surface along the terminal por- 

 tion, leaving only a narrow naked line along the back, but farther from 

 the tip this naked space becomes gradually wider and the band of suck- 

 ers narrower, and after these crowded bands of suckers cease, scattered 

 suckers, placed mostly two by two, extend for some distance along the 

 proximal part of the arms. The suckers of the tentacular arms are so 

 small that their form cannot be seen with the naked eye ; they are deep, 

 cup-shaped, with a small circular aperture, supported by a horny rim, 

 which is often armed with two or three sharp teeth on one side (fig. 2 c). 



Color of body and arms, so far as preserved in alcohol, deep brownish 

 orange ; on the upper side of the back and caudal fin the color is better 

 preserved, and shows small, occellated, circular spots of orange-brown, 

 with an inner circle of whitish and a central spot of purplish brown. 

 Similar spots also exist on the head and arms, and also on the lower side 

 of the body, where the color is best preserved. 



A considerable amount of a bright orange oily fluid, insoluble in alco- 

 hol, exuded from the viscera.. Examined by means of the spectroscope 

 this fluid absorbed part of the green, all of the blue, and most of the 

 violet rays. The stomach contained fragments of small Crustacea. The 

 pen is pale yellow, thin, and slender anteriorly, with two sublateral 

 costse, and narrow delicate margins outside the costae ; in the middle it 

 becomes still thinner and narrower, with the margin inrolled ; farther 

 back the margins become much wider and then unite together ventrally, 

 forming a long, hollow, conical portion, extending to the acute posterior 

 tip ; this portion is not so broad as deep, and has a slight dorsal keel 

 and a ventral groove.
