are comparatively long, subequal, and provided with scattered setse. The multi- 
articulate flagellum is scarcely as long as the peduncle. 
The maxilliped (fig. 2a) has a comparatively stout basal joint and a distal masticatory 
obe about three-quarters of its length. The entire inner margin is straight, and not far 
from the base of the masticatory lobe are two papilliform teeth separated by a distinct 
interval. The distal extremity of this lobe is straight and its outer margiu rounded. 
At the extremity and below the edge are three broad, denticulate spines. Three more, 
situated externally, are apparently simple ; but this is due to their being seen sideways. 
The palp is five-jointed. The first three progressively increase in breadth, the first 
being very short, and the next two subequal in length, both these are setose on their 
inner margins, and the larger ones on their distal external borders also. The two 
terminal joints are comparatively slender, subequal in length and setose distally. The 
epignath is large, conical. A small rounded base, bulging considerably to terminate 
as a cone, it reaches nearly to the end of the masticatory lobe. 
The pereiopods are not of any great length, and are very much alike throughout. 
The first pair only is modified to any extent. This is short, the basis is the longest 
joint. The ischium is about half the size. The merus is shorter still, but dorsally it 
is carried as a spine over the carpus for fully half its length, the carpus itself being 
rather swollen ventrally and proximally, having two or three stout spines about its 
centre. The propodus is stout and but little shorter, and also carries a few spines 
ventrally. The terminal claw is stout, the “ nail ” is distinct, and has a small 
accessory. The remaining pereiopoda are very much the same, only longer and much 
more slender. This involves an increase in the length of some of the joints, and the 
carpus and propodus are the most affected. In the two posterior pairs the merus forms 
a pronounced dorsal lobe over the base of the carpus. 
The first pair of pleopods forms a stout operculum over the remainder, and 
together form a rather narrow band, which widens out about two-thirds of its length, 
from thence it tapers to a blunt point; the margins are setose. 
As only a single individual of this species was taken, I have been unable to go 
into any very great detail. The maxilliped of one side has been removed for 
examination, but that is all.

CoULMANNIA FRIGIDA. 
Specific characters :— 
First segment of the mesosome with only one epimeral blade. 
Urosome prolonged as a distinct spine. 
During the progress of this Report an Isopod was sent me from the British 
Museum which had been found clinging to the body of Colossendeis frigida. This 
specimen I at first thought to be identical with the preceding, but a very brief 
examination shows that it is quite distinct.
