534 Records of the Indian Museum. [VoL. XI, 
came out during the night and made fresh ones, in the centres 
of which they remained so long as they were not disturbed. 
Uloborid webs were several times seen grouped round the web 
of Psechrus alticeps in Cochin. One species seems to be definitely 
associated with Cyrtophora ciccatrosa in the Indian Museum com- 
pound, though I never saw it here till towards the end of last 
year. A somewhat larger species lives in groups of orb-webs in 
the Museum compound, but does not appear to be specially asso- 
ciated with any other spider. This species, and perhaps one other 
of similar habits, occurs also at Pusa, where Uloborids are found in 
association with Nzlus sp., Gasteracantha brevispina, and Cyrtophora 
ciccatrosa. Another species found at Pusa spins solitary orb-webs 
over slight depressions on the sunny side of the trunks of smooth- 
barked trees. 
One Uloborid found singly in Cochin spins two horizontal 
orb-webs, one above the other. The upper web is flat and finely 
spun, with a meshed hub on the under side of which the spider 
rests. The lower web is funnel-shaped with open hub, and is of 
coarser build. 
Psechridae. 
Psechrus ? singaporensis has been found in the Batu Caves, 
Selangor, out of reach of daylight (Flower, J. Straits R. Asiatic 
Soc. No. 36, July, rgo1, p. 45). 
Psechrus alticeps spins a large irregular web not unlike that 
of a Theridiid. One end of this web is always in contact with a 
tree-trunk, stone or bank of earth, to which the spider escapes 
with extraordinary rapidity when disturbed. ‘The species is very 
common in the Cochin timber forests, but very difficult to catch. 
A species of Psechrus, common at Pashok and Kalimpong in 
the Darjeeling District (ca. 4000 ft.), constructs a large and 
coarsely spun tunnel, the upper part of which spreads out to form 
a somewhat extensive roof-like snare—something like a Pardosa 
web (see below) inverted, but coarser in every way. ‘The structure 
of the snare resembles that of the snare of Stegodyphus described 
below. Ihave not been able to examine a fresh snare in detail, but 
a microscopic examination of an old one showed that the silk was 
also very like that of Stegodyphus both in structure and in variety. 
Eresidae. 
The genus Stegodyphus is represented in India by several 
species ; but only one, S. sarasinorum, seems to be abundant. The 
abundant and widely distributed form whose habits are described by 
Jambunathan (Smithsonian Misc. Coll. XL,VII, pp. 365-372, pl. L.') 
must presumably therefore have belonged to this species, on the 
habits of which Fischer has since contributed a few notes 
(J.B.N.H.S. XVIII, pp. 206-7).
