232 Mr, A. O. Walker on the Isopoda and Amphipoda 
Lanceola sp. 
Two specimens too young for identification, viz. :—Net 5 e, 
1070 fath., 6 millim.; net 6g, 560 fath., 4 millim. 
Most of the species of this genus are very large; those 
described by Bovallius range from 10-13 millim. (L. felina) 
to 42 millim. (L. Sayana). A species figured in the ‘ Chal- 
lenger’ Report from a drawing by Willemoes-Suhm is 
supposed to have been 70 millim. in length. 
Vibilia armata, Bovallius. 
Net 46, 790 fath. 1 specimen, 9 millim.

be identified. 
V. erratica, Chevreux, from the Mediterranean, is very 
near to this species, but has the last two segments of the 
urosome distinct, while in V. armata they are coalesced. 
Tribe GAMMARIDEA., 
Cyphocaris anonyx, Boeck. (Pl. XVIII. fig. 14.) 
(=C. micronyx, Stebbing.) 
Four specimens, of which one from 1300 fath. appears to 
be-an adult male. 
4k, 1670 fath. J young. 
5g, 1800 fath. 1 adult male, 1] millim. 
6f, 510 fath. 2 young, 24 and 3 millim. 
There can, I think, be no doubt that Boeck overlooked 
the very small dactylos of the second gnathopods, the appa- 
rent absence of which gave rise to its specific name. ‘The 
principal apparent difference between this species and 
C. micronyz is that the distal extremities of the first and 
second perzeopods are somewhat more dilated in the latter. 
Orchomenopsis abyssorum (Stebbing). 
Three specimens, all females. 
47, 1570 fath. 1. 
5h, 1410 fath. 1. 
5k, 1610 fath. 1. 
I have to thank Mr. Stebbing for verifying this species 
and Scina Rattrayi.
