1915.] F.H. Gravety: Indian Mygalomorph Spiders. 279 
Mr. P. B. Kay enabled me to find without delay the most promis- 
ing collecting grounds of the neighbourhood. Only one specimen 
of the present species was obtained. 
@. Unknown. 
9. Dimensions.—-Catrapace 13:0 X 98 mm. Sternum 
61 X 555mm. First legs fully as long as fourth which are slen- 
derer than any of the others; second shorter than first and fourth, 
longer than third. Carapace not quite as long as patella and tibia 
of first legs, much longer than femur and than tarsus and meta- 
tarsus of same, and than femur or patella and tibia or tarsus and 
metatarsus of second legs; fully as long as femur and patella of 
third legs, scarcely as long as tibia metatarsus and tarsus of same; 
about equal to femur and haif patella, to patella and tibia, and 
to tarsus and metatarsus of fourth legs. 
Colour.—Reddish brown, except the upper sides of the patella 
and tibia of the second legs which are paler, almost golden; and 
of the patella, tibia, and base of metatarsus of the first legs which 
are paler still and greyish. 
Structure.—The shape of the carapace resembles that of the 
preceding species. The anterior median eyes are larger than the 
anterior laterals, the diameter of the former being about equal to 
the long diameter of the latter. ‘The fovea is lightly procurved 
and very deeply inipressed. The /abium is normal, the sternum 
is very hairy, with large sigilla which are rounded in front and 
pointed behind. ‘The chelicerae resemble those of Plesiophrictus 
apart from the presence of stridulatory spines upon them. There 
is the usual mid-apical spine on the metatarsi of the first pair of/egs, 
but it is much hidden by the dense scopula. I have not been able 
to detect any spine on the second metatarsus, but here too the 
scopula is very dense. The metatarsi of the two hind legs each 
have three apical spines. ‘The tibiae of the palps and of all the legs 
are unarmed. ‘The tarsal and metatarsal scopulae are divided in 
the fourth leg only. The metatarsal scopulae of the first two legs 
ate very dense, and extend to the base of the segment. Those of 
the third legs, though dense, only cover the distal half of the 
segment. ‘Those of the fourth legs are weaker and apical. 
This species differs from H. nilgivinus in that the fourth leg 
is longer than the second, and from H. cervinus in that the 
patella and tibia of the first are together longer than those of the 
fourth. From both it appears to differ in colour, but this differ- 
ence may be less real than it seems as its most striking feature— 
the light grey of the upper surface of the patellae and tibiae of 
the anterior legs—is not apparent as long as the specimen remains 
superficially wet. 
Genus Thrigmopoeus, Pocock. 
A single immature specimen from South Arcot is the only 
representative of this genus which we possess. Its stridulating 
organ differs from that of Haploclastus kayi in the more definite 
arrangement and slightly greater size of the spines on the palps,
