Goree Island, Senegambia. 271 
pubescence, which is absent (perhaps from abrasion) on the 
median and most elevated portion of the body. The antero- 
lateral margins are entire and apparently somewhat flattened 
on the hepatic regions. The front is triangulate and deflexed, 
with a small tuberculiform tooth above the inner orbital 
hiatus. Hpistome triangulate. The buccal cavity has appa- 
rently no longitudinal palatal ridges, and has three fissures in 
its anterior margin. The male postabdomen is narrow- 
triangulate, with all the joints apparently distinct, and is 
covered, as is all the inferior surface of the body, with a 
dense fulvous hairy coat. Hyes well nigh concealed in the 
deep orbital cavities, which are very incomplete below. Basal 
joint of the antennules much enlarged. Basal antennal joint 
occupying the large hiatus beneath the ocular peduncles. 
Outer maxillipedes with the merus joint as long as the 
ischium, and truncated at its distal end, articulated at its 
antero-internal angle with the next jot; exognath narrow. 
Anterior legs or chelipedes of moderate length, densely hairy, 
but apparently without spines or tubercles; fingers naked, 
excavated, and strongly dentated at their apices. Ambulatory 
legs of the first two pairs somewhat flattened above, clothed 
with longish fulvous hairs; terminal joints slender. In the 
fourth and fifth pairs of legs the spiniform terminal joint is 
reflexible against a spiniform process of the penultimate joint. 
Colour of the single specimen (a male in spirit) light yellowish 
or fulvous brown; tips of fingers white. Length nearly 
4 lines (8 millim.), breadth 5 lines (nearly 11 millim.). The 
specimen has been somewhat crushed and its natural outline 
thereby altered. 
Dromia spinirostris, sp.n. (Pl. XVI. fig. 2.) 
In this species the carapace is rather convex, a little broader 
than long, and clothed with a short close pubescence, which 
is absent in certain places; the surface is rather uneven, 
there being an obscure rounded prominence on each branchial 
region near the branchio-cardiacal suture, which, however, is 
very faintly defined; nor are the other sutures of the carapace 
indicated. The rostrum is composed of two rather prominent 
conical and slightly divergent spines ; there is a short spine 
at the inner angle of the orbit, and another on its lower 
margin ; four small dentiform spines on the lateral margins of 
the carapace, one on the subhepatic region, and one at the 
antero-lateral angles of the buccal cavity. The inferior sur- 
face of the body is clothed with a dense pubescence; the 
buceal cavity has no longitudinal ridges on the palate; the
