Sars). The metasorae, which is undivided, is somewhat 

 triangular in form and rather narrower than the segment of 

 tlie niesosome to which it is articulated. The sides of the 

 nietasome converge gradually and equally to the blunt-pointed 

 apex, as shown in the drawing, and its length is equal to 

 about one fifth of that of the entire animal. 



Pleurocrypta cluthce appears to some extent to combine the 

 characters of P. llendersoni and P. Patiencei, the female 

 being not unlike the female of the latter species, while, on 

 the other hand, the male is very nearly similar to the male 

 of the former. 



All the three species I have recorded appeared to be fully 

 mature.

 Tryphana JlJalmu, Boeck. 



A single specimen of this somewhat rare Amphipod was 

 obtained in the deep water about 9 or 10 miles off Aberdeen. 

 Prof. G. O. Sars states that Boeck obtained his specimens at 

 a considerable depth in the outer part of the Ilardangerfjord 

 in Norway, and that it has been taken by himself at three 

 other localities*. Bovallius records its occurrence off the 

 Fseroe Islands, and the Rev. T. li. 1?. Stebbing in the North 

 Atlantic, lat. 18° 8' N., long. 30° 5' W. ; but apparently the 

 only British record other than tlie present is that of the 

 Rev. A. M. Norman, who, on behalf of the late T. Edward, 

 records it from Banff f. 



It is customary by some learned authors to modify "jTrj/- 

 pJianOf^^ the nasie adopted by Boeck, and use ^^Trf/p/uena^' 

 instead ; but the Rev. T. R. R. Stebbing does not apj)rove 

 of the change, and considers that the name as used by Boeck 

 ought to be retained.
