segment in the former is much more produced and curved 
than in the latter. Bate and Westwood’s figure differs 
from both as figured by Hansen in the shape of the telson; 
also in the second uropods, which they figure as spinous, 
but describe as ‘‘simple.” In my young specimen these 
have a single spine about one-third of the length of the 
ramus from the peduncle, and a similar spine on the 
inner (?) ramus of the third uropods about the middle. 
*Orchomene goésw, Boeck. 
I.d. A single specimen. New to the British lists. 
Distinguishable by the short and wide hand and wrist of 
the first gnathopod, and by the very broad peduncle and 
short rami of the third uropods. yy 
*Tryphosa horingi, Boeck. 
I.a. Three specimens. New to British lists. 
Tryphosa ciliata, Sars. 
I.a. One specimen. I question whether this is distinct 
from 7’. nana, Kr. 
*Huonyx chelutus, Norman. 
Euonyx chelatus, Norman, ‘‘ Brit. Assoc. Rep.,” 1866. 
Opis leptochela, Bate and Westwood, ‘‘ Brit. Sess. Crust.,” vol. ii., p. 501. 
One specimen off the Lighthouse. I. Norman, in his 
report on the Shetland dredging, /.c., describes this species. 
As the first gnathopods have the hand long and slender 
instead of very large, according to the character of Opis, 
as defined by Kroyer, it should not in any case have been 
referred to that genus. Norman says it is parasitic on 
Echinus esculentus. In my specimen the second gnathopod 
is not so hairy as shown in Bate and Westwood’s.figure, 
and the tooth or hump on the dorsal surface of the fourth 
pleon segment is much more marked. 
Bathyporeia pilosa, Lindstrom. 
II., E.L. In immense numbers, of both sexes.
