progressively increase in length, the former having a sinuous posterior border and 
rounded lateral margins, setose as the more anterior ones, the latter is curved slightly 
backwards, the lateral margins curved and setose. and the posterior sinuous. 
Intervals of varying width exist between the segments. 
The metasome consists of a single plate, the urosome, which is attached by about 
one-third of its width; it enlarges rapidly to its full width very little less than 
that of the preceding segment; it is broadly cordate in shape; the antero-lateral 
margins bear small sete, and are in part very finely and sparsely serrate. 
Three small teeth occur in front of the uropoda, which are of moderate size, 
ventral in origin, and preterminal in position, They comprise a single-jointed 
protopodite with a small single-jointed exopodite and endopodite. The former is 
about two-thirds the length of the latter and much more slender; each bears a tuft 
of long setee and a few along both margins. 
The first antenna consists of a peduncle of two joints, the first of which is stout, 
the second longer and more slender; the flagellum is small, little longer than the 
second joint of the peduncle. 
The second antenne are destroyed in the specimen figured, four joints of the 
peduncle remain; all are short, and the third of them carries externally a spinous 
appendage. In another smaller example the second antenna is complete and shows two 
more joints, long and stout, the distal one longer than the proximal and a little more 
slender; both are covered, but not thickly, with fine sete. The multi-articulate 
flagellum is about as long as the terminal joint of the peduncle; it is well provided 
on the inner side with specialised setae in small groups. 
The mouth parts are quite normal as figured on Plate VIII. 
Of the pereiopoda the first is the shortest and a little the stoutest, the remainder 
are approximately subequal. They do not present any special features save that the 
terminal claw is well developed and accompanied by an accessory which is very nearly 
as large. 
The pleopoda. The first pair are opercular. 
Four specimens were obtained from the dredge material during February, 1902, 
taken inside the 20-fathom line. The largest is 3 mm. long. 
COULMANNIA. 
Cephalosome narrower than any segment of the mesosome except the last; the 
eyes are small and borne on elongated lateral peduncles. 
» Second antenna with a six-jointed peduncle, no accessory appendage on the third 
joint. 
Mesosome without any conspicuous division between anterior and posterior portions. 
Epimera not distinct from mesosome, prolonged and deeply cleft. Segments 
spinose in mid-dorsal line.
