CRUSTACEA OE FEANZ-JOSEF LAND. 75 



cusp instead of two. The species otherwise are closely related; 

 but as the difference referred to appears to be fairly constant, 

 and as there are one or two points in which a disagreement 

 between the two forms is observed, it is more satisfactory to 

 regard this as a distinct species than simply as a variety. More- 

 over, both forms have an extensive distribution. P. monocuspis 

 is represented in the collection of Franz-Josef Land Crustacea 

 by two specimens, one of which was obtained off Bear Berg, in 

 about 10 fathoms, on September 27th, 1896 ; and the other about 

 one mile off Flora Cottage, in 15 fathoms, on the 10th of the 

 same month. Prof. Sars records the species from Grreenland 

 and from Norway ; and it is also a member of the British fauna 



Grenus Pabapletjstes, Buchholz, 1874. 



Pabapleijstes glabee (Boeck). 



1860. Amphithopsis glaher, Boeck (4), p. 662. 



This species is represented by a single specimen captured off 

 Bear Berg, in 10 fathoms, on September 27th, 1896. It has 

 been recorded from various other Arctic localities, and south as- 

 far as Christiania Fjord and the Kattegat. 



Grenus Acanthonotosoma, BoecJc, 1876. 



ACANTHONOTOSOMA CEISTATITM (Owen), 



1835. Acanthonotus cristatus, Owen (61), p. 90, pi. B. figs. 8-12. 



This species is included in the collection of Crustacea from 

 Franz-Josef Land, but was dredged somewhat to the south of 

 that Archipelago in lat. 77° 53' N., long. 53° 20' B., at a depth 

 of 130 fathoms, on July 11th, 1897. Groes records this from 

 Spitzbergen, Hoek from Barents Sea, and Hansen from the Kara 

 Sea ; while Mr. Stebbing records the occurrence of a specimen 

 from lat. 75° 14' IST., long. 44° 26' E., from a depth of IBQ 

 fathoms. Goes's Spitzbergen Station [(Heenloopen Strat) is 

 somewhat farther north than that of Mr. Bruce.
