70 ME. THOMAS SCOTT ON THE 



contained in the Bruce collection ; most of tke specimens 

 were collected in the neighbourhood of Cape Flora, especially 

 about two- thirds of a mile south-west of Elmwood. Some were 

 collected in January 1897, and others during April, May, June, 

 and July. Several of the specimens were of large size : Prof. 

 Sars states that 40 millim. is about the maximum length of Arctic 

 specimens ; one or two of the largest in the Bruce collection 

 measured from 40 to 42-5 millim. 



Anonyx nugax seems to be one of the more commonly distri- 

 buted species in the Arctic seas. Prof. Sars {loc. cit.) gives 

 Pranz-Josef Land among the places mentioned in his note on the 

 distribution of the species. I have obtained on two separate 

 occasions in the Pirth of Porth what is certainly the same 

 species. 



Genus Hoplontx, G. 0. Sars, 1890. 



HoPLONTx siMiLis, G. 0. Sars. (PI. 9. figs. 11-13.) 

 1890. Hoplomjx similis, G. O. Sars (75), p. 93, pl. 33. fig. 1. 

 A single adult female specimen (with ova) of an Amphipod 

 which 1 ascribe to this species was taken about two-thirds of a 

 mile south-west of Elmwood, in 18 fathoms water, on May 22nd, 

 1897. At first I thought it might be a specimen of Hoflonyoc 

 cicada (Fabricius), as that is said to be a widely distributed 

 species in the Arctic Seas, but a more careful examination showed 

 that the form of the fourth coxal plates (fig. 11) and of the last 

 cpimeral plates (fig. 12) difi"ered from those of that species, while 

 they agreed very closely with those of S. similis, Gr. 0. Sars. 

 In this specimen the integument is ornamented with numerous 

 circular dejjressions as exhibited by the figures. 



Grenus Pseudalibrotus, Delia Valle. 



* Pseud ALiBEOTUS littoralis {Kroyer). 



1845. Anonyx littomlis, Kroyer (46), 2 R. 1 B. p. 621. 



This species was obtained by Mr. Bruce on several occasions, 



* Prof. Sars, in ' Crustacea of Norway,' vol. i. p. 102, expresses some doubt 

 as to whether M. -Edwards's generic name Alibrotus is correctly applied to this 

 northern form, but he does not propose any substitute for it. More recently, 

 however, Delia Valle instituted a new genus, Pseudalibrotus, for Kroyer's species, 

 .and I have adopted this name here.
