Indian Deep-sea Trawling. 525 
there are small spines on the distal ends of the second, third, 
and fourth joints of the antennary peduncle. 
The eyes are non-pigmented, non-facetted, and are ter- 
minal on the freely movable eye-stalks. 
External maxillipeds fairly stout, the inner edge of the 
ischium is entire, while the ventral border of the merus has 
two strong teeth. ‘The chelipeds are as long as the carapace 
minus the rostrum, and nearly twice as long as the second 
pair of legs. The eggs are small, orange-coloured, and fairly 
numerous: in the specimen under description there are 
twenty-five. 
A single specimen, an ovigerous female, dredged off the 
south coast of Ceylon, at Sta. 277, from 880 fath. 
It very closely resembles Elasmonotus cylindrophthalmus, 
but it has not got the characteristic eyes of the latter, and the 
external maxillipeds are different. 
Named after Lieut. C. I. Sinclair, Royal Indian Marine, 
who has been for many years on the R.I.M.S. ‘Investigator,’ 
and has shown a naturalist’s keenness in the dredging portion 
of the ship’s work. 
Family Galatheide. 
Urorrycuus, Henderson. 
Uroptychus nanophyes, sp. n. 
Carapace longer than broad, practically smooth, though 
with the lens minute spines can be made out on the dorsum, 
especially in the male. The lateral margins are armed with 
six large spines arranged regularly, three in front and three 
behind the cervical groove, the posterior three being the 
larger. 
Rostrum horizontal, acutely triangular, half as long as the 
carapace, and with three or four very small teeth on each 
side; it extends well beyond the antennulary peduncle. 
The eyes are well pigmented, terminal, hardly broader 
than their stalks, and extend about half the length of the 
rostrum. 
The acicle of the antennary peduncle is very long, extending 
almost as far as the tip of the rostrum in the female, and 
nearly as far as this in the male. The flagella of the 
antennules are very unequal, the outer being long and the 
inner very short. 
The chelipeds are very long and strong, twice as long as 
the body, and over twice as long as the other legs. The 
ischium has a large spine at its distal end, and two smaller
