 pis. xli., xlii. 



A specimen, li inch in length, and two of smaller size, 

 were obtained at 70° 51' N., 53° E., in about 20 fathoms 

 depth, comparatively shallow water for this apparently rare 

 species. 



CUMACEA. 



In this group the only captures observed were Leucon 

 jyallidus, Sars, from a depth of 60 fathoms, and some small 

 specimens taken with the tow-net, probably belonging to 

 Lan\props fuscata, Sars; but the lateral margin of the cara- 

 pace is furnished with five or six denticles, the first joint of 

 the inner branch of the uropods has only six spines, and the 

 apex of the telson scarcely looked as if it could have been 

 furnished with more than three spines, the full number in 

 L.fvscata being five.

This minute species, less than -^ inch long, diflFei-s from 

 the Cryptocope Voringii and Cryptocope abhreviata in liavlng 

 seta3 on the pleopods, of which the other two species are 

 devoid. The setee are apical in the specimen I have examined. 

 It has the antennai agreeing with those figured by Hansen in 

 pi. vii. fig. 1 h for the female. Also apparently the outer 

 branch of the uropod is two-jointed, in agreement with 

 Hansen's figure of that microscopic appendage in the ovigerous 

 female. According to Sars the outer branch is one-jointed in 

 the female both of C. abhreviata and of the larger C. Voringii^ 

 although in 1876, when describing the latter as Tanais 

 Vbringiiy he had stated that both branches of the uropods 

 were two-jointed in the female. 



Mr. Bruce's specimens came from a depth of 100 fathoms.
