114 MR. F. E. BEDDARD ON ISOPODA COLLECTED __[ Feb. 2, 
from that family on account of the branchiate uropoda; but Anuropus 
should at least be regarded as the type of a special subfamily 
equivalent to any of the other four, viz. Cymothoadiens errants, 
C. raviseurs, C. branchiferes, and C. parasites, into which MM. H. 
and A. Milne-Edwards have divided the family. Anuropus has a 
further ‘‘abyssal character” in the absence of eyes, and it is 
also remarkable for the abortive antennules, which are only repre- 
sented by two joints—a stout basal joint, and a longer stout curved 
distal joint, which is possibly the equivalent of a metamorphosed 
flagellum. The single species I may term 
1, ANUROPUS BRANCHIATUS, 0. sp. 
The extreme length of the specimen, which is a female, is 70 millim. 
The head is small, and entirely without eyes; the body is extremely 
convex ; the thoracic segments are subequal, the six posterior are 
furnished with distinct epimera; the abdominal segments are all 
smaller than the thoracic segments and subequal ; the fifth segment is 
fused with the telson and forms a caudal shield, which is rounded and 
flattened in shape. ‘There is no trace of eyes; the antennules are 
short and thick, consisting of a thick basal joint and a longer, some- 
what curved distal joint. The antenne are longer and more slender, 
and quite normal in structure; the mandibles have a three-jointed 
palp. The abdominal appendages are all similar to each other, 
consisting of a short, stout, basal joint, and two equal rami flattened 
and rounded in form.

Fam. SPH ZROMIDS. 
Genus Cymopocea, Leach. 
1, CYMODOCEA ABYSSORUM, 0. sp. 
This species is the only representative of the family at present 
known from deep water ; it is represented by two individuals, one a 
male, the other a female. The body in both is flattened, and is 
evidently incapable of being rolled into a ball. The eyes are small 
and whitish from the absence of pigment ; the first thoracic segment is 
broader than the head, the following segments are subequal, and with 
well-acveloped sickle-shaped epimera, absent in the last of the seg- 
ments. Abdominal shield with two bluat conical spines on the dorsal 
surface, one behind theother ; posterior extremity obtuse and rounded. 
Uropoda with the rami subequal in the female, the outer being 
slightly the longer; in the male the outer ramus is very much longer 
than the inner and curved inwards.

Fam. APSEUDID2&. 
Genus ApseupEs, Leach. 
1. APSEUDES ANTARCTICA, 0. sp. 
The largest specimen of this small species measures 4 millim. in 
length. The cephalothorax is nearly as long as the first four segments
