Sars established this species on a single immature female, s 1 , mm long, taken in a depth of only 

 30 35 fath. From a few stations I have several specimens, among them two females with marsupium, and 

 in some essential points they show so much similarity to Sars' representation of . hispida that they arc 

 referred to this species, though they differ in a few particulars of probably slight importance and excepting 

 one specimen have been taken in rather considerable depths. 



The carapace and all segments of the t>ody have a number of thin hairs, but not nearly as many as 

 drawn by Sars in his fig. 95. The anterior part of the lower margin of the carapace is nearly straight (tigs. 8 a 

 and 8 b). with small saw-teeth, but the angle between this line and the front margin is distinctly larger than 

 shown by Sars (his fig. 96). The antero-inferior tooth is straight, nearly horizontal, long or very long. The front 

 margin between this large tooth and the next tooth is rather long, scarcely or slightly concave and without 

 vestige of any tooth. The antennal notch is in females deeper and more triangular than figured by Sars, with 

 a small denticle on the lower and two denticles on the upper margin; in the immature male this notch is 

 scarcely developed, and the front margin between the upturned tooth at the upper end and the downwards 

 curved tooth farther below is feebly concave without serration. The abdomen is long and robust as figured 

 by Sars. 



The antennula- (fig. 8 a) are somewhat robust, with many seta;; terminal joint of the peduncle almost 

 as long as the outer flagellum. in which first joint is proportionately very long, more than three times as long 

 as the second. First pair of legs moderately slender ; propodus considerably longer than carpus and slightly 

 more than twice as long as the dactylus. Second pair of legs are robust ; carpus is very distinctly longer than 

 merus and about as long as the two distal joints combined. The uropods (fig.Sc) are robust and very char- 

 acteristic, agreeing with Sars' fig. 97; the peduncle is as long as the endopod, with a good number of spines 

 at the inner margin : first joint of the endopod is very long, in adult specimens t>etween five and six times 

 as long as second joint, and it has numerous, in the specimen drawn 15, spines along the inner margin ; second 

 joint has j small spines on the inner margin and terminates in a very robust spine slightly shorter than the 

 joint, and besides its end has a moderately long, thick seta; the exopod, which reaches slightly or somewhat 

 beyond the end of first joint of the endopod. has numerous strong seta; not only along the inner margin but 

 about five on the dorsal surface, and some shorter seta; on the outer margin. 



Length of the adult female 7.2 mm.
