Museum, and

Naturalist, Marine Survey of India.

During the season 1910-11 it was unfortunately only possible 
to make four hauls of the trawl in deep water; but at one of the 
stations a large number of interesting Decapod Crustacea were 
obtained and, inasmuch as many of these species appear to be 
rare, we have thought it as well to draw up a few notes on the 
collection. 
The only species hitherto undescribed is a Macruran of the 
genus Merlipfolyte, the first representative of the family Hippoly- 
tidae which has yet been found in deep water off the coasts of 
India. A small crab, allied to the genus Carcinoplax, also seems 
to belong to a species as yet unknown; this specimen is being 
referred to Col. Alcock and is not included in the present account. 
Of the others in the collection perhaps the most interesting is 
the male of Avisteomorpha rostridentata (Bate), a species previously 
known from females only. Pentacheles hextit of Alcock is identified 
with the Atlantic and Mediterranean Polycheles typhlops and our 
knowledge of the distribution of several other scarce forms has 
been considerably extended. 
The stations at which the collection was made are all situated 
off the S.W. coast of India ; they are— 
St. 388. 26-iv-11. 7° 44’ 107_N, BVA 35 45” E. 670 fathoms. 
St(380. (27-1v-15)) "QP OF 50INS 75°-55° 50. Be Or 
A considerable number of corals (Caryophyllinae) were 
obtained at this station. 
St. 390. 27-iv-II. 9° 09’ N., 75° 46’ E. 260 fathoms. 
On this occasion the net caught on a rock and was badly torn. 
No Decapoda were taken. 
St. 3901. 27-iv-II. 9° 14’ 10” N., 75° 45’ EK. 237 fathoms. 
This haul was remarkable for the large number of the Gas- 
tropod, Xenophora pallidula, which were obtained. The 
majority of the Decapoda which form the subject of the 
present paper were found at this station.
