Sars). The metasome, which is undivided, is somewhat 
triangular in form and rather narrower than the segment of 
the mesosome to which it is articulated. The sides of the 
metasome 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 cluthe appears to some extent to combine the 
characters of P. Hendersoni and P. Patiencet, 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. 
(2) AMPHIPODA. 
Tryphana Malmii, 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 Hardangerfjord 
in Norway, and that it has been taken by himself at three 
other localities *. Bovallius records its occurrence off the 
Feroe Islands, and the Rev. T. R. R. Stebbing in the North 
Atlantic, lat. 18° 8’ N., long. 30° 5’ W.; but apparently the 
only British record other than the present is that of the 
Rev. A. M. Norman, who, on behalf of the late T. Edward, 
records it from Banff +. 
It is customary by some learned authors to modify “ Try- 
phana,” the name adopted by Boeck, and use “Tryphena” 
instead ; but the Rev. T. R. R. Stebbing does not approve 
of the change, and considers that the name as used by Boeck 
ought to be retained.
