*Triteta gibbosa, Bate. 
Atylus gibbosus, Bate and Westwood. 
Not uncommon on Sponges, Ascidians, &c. I., II., III. 
Most easily obtained by placing freshly gathered pieces of 
Halichondria panicea in sea water, when it emerges from 
them. 
Halirages bispinosus, Bate. 
ae LV. 
Calliopius leviusculus, Sp. Bate. 
Very abundant. I.d. All the specimens taken were 
freckled with red. This species varies in colour remarkably 
in different localities. At Colwyn Bay it is generally 
ereenish white, while those I have seen from Penmaen- 
mawr were olive coloured. 
*Calliopius norvegicus, Rathke (?). 
Llandudno. I.0., I[I., IV. Itis remarkable that this 
species, which has not been previously recorded as British, 
should this year have been taken at all the above localities, 
at Bull Bay ([V.) abundantly. Mr. Stebbing informs 
me, however, that it 1s not uncommon at Ilfracombe. 
Meinertt and Zaddacht do not consider it distinct from 
the preceding. I am surprised at this statement, for the 
longer and more slender antennex, the teeth on the under 
side of the last joints of the peduncle of the upper antenns 
in the male (in place of the strong tooth at the distal 
extremity of the last joint in C. leviusculus), the smaller 
and weaker gnathopods with the wrist not produced into a 
spur, and lastly the angulated hind margin of the third 
pleon segment above the lower angle, make the distinction 
unmistakeable. At the same time, I doubt whether
