Plate XLIII, figures 1, 2, female. Plate XLIV, figure 2, male. 



Female (type-specimen): body broad, stout, depressed, slightly emar- 

 ginate at the posterior end, rather soft to the touch, and in some speci- 

 mens gelatinous in appearance ; a thin, soft, free, marginal membrane 

 runs along the sides and around the posterior end of the body, becom- 

 ing widest (about 12 mm ) posteriorly ; in some of the more strongly con- 

 tracted specimens this membrane is but little apparent. Head huge, 

 broad, depressed, with the eyes large and far apart; above each eye 

 there is a small, simple, conical, acute, contractile cirrus. A well de- 

 veloped, thin Aveb connects the arms, considerably above their bases, 

 and then runs up to the tips as a broad margin to each arm. 



The arms are rather large, stout at base, with a broad inner face, and 

 taper gradually to very slender tips; the first and third pairs are nearly 

 equal in length : those of the second are also about equal in length to 

 the fourth pair, but are somewhat shorter than the first and third. The 

 arms on the right side are all somewhat longer than the corresponding- 

 ones on the left. The arms, measuring from the beak, are more than 

 twice as long as the body. The suckers are arranged in two distinct 

 rows, to the base. 



Color of head and body, above, and of body, beneath, deep reddish- 

 brown, closely specked with darker brown, and with many small round- 

 ish spots of whitish on the body and arms. 



Length of the type- specimen (female) from the beak to end of body, 



not including marginal web, 00 u,m ; breadth of web, 22 ; total length, 104 ; 



breadth of body, 40; breadth of head across eyes, 32; of eye-openings, 



10; of eye-balls, 17; length of mantle, beneath, 38; length of first pair
