nearly as deep as the segments to which they are attached. 
Gnathopoda having the propoda pear-shaped, with the palm 
oblique, and as long as the superior margin, which is nearly 
straight; inferior margin convex and posteriorly produced ; 
palm defined by one or two movable spines. Anterior segments 
of the tail with the posterior angles pointed. Length 3 inch.” 
I have not yet been able to examine a specimen of this species, 
though Bate and Westwood record it from Ringwood in Hants, 
Corsham in Wiltshire, and High Elms in Kent. It appears to be 
readily distinguished from the other British species by the pear- 
shaped propoda of the gnathopods and by the oblique palm. It 
is given by Wrzesniowski as a good species. 
Specimens identified by Messrs. Hornell and Sinel as WV. fon- 
tanus have been found in two wells on the outskirts of St. Helier, 
Jersey, and are mentioned by Messrs. Walker and Hornell in 
their report on the Schizopoda &c. of the Channel Islands. 
T have endeavoured to trace these specimens or to obtain others 
from the same locality, but without success, although Mr. Hornell 
used his best efforts on my behalf.

I have given above only the most important references bearing 
on this genus; a full historical account of it will be found in the 
one last given. Vejdovsky, however, has not given an amended 
diagnosis of the genus, and in order to avoid confusion, I shall 
not attempt to do so either, as that will, I presume, be done by 
Mr. Stebbing in his forthcoming account of the Amphipoda for 
“ Das Tierreich.’ 
It is closely allied to the genera Paracrangonyx and Eucrangonyx 
recently established by Mr. Stebbing. Boruta, Wrzesniowski, 
is also very nearly allied to Crangonyzx, and is indeed considered 
by Vejdovsky to be identical with it; while Goplana, Wrzes- 
niowski, is considered by him as merely asubgenus of Crangonyz, 
and the species Goplana polonica as a surface-species repre-
