524 Records of the Indian Museum. [VoL. XI, 
far as I know its habits are much the same as those of the Ceylon 
species. 
Schizomus crassicaudatus was only found under bricks, etc., on 
or close to open ground (usually grassy lawns) more or less shaded 
by trees, while the other two Ceylonese species named were found 
only among dead leaves, especially where these formed a layer of 
considerable depth and were matted together by fungal hyphae, in 
the midst of the shrubberies in the Peradeniya Botanical Gardens. 
Schizomus crassicaudatus was never found in company with the 
other two. 
The ground was more or less moist, especially in the shrub- 
beries, during almost the whole time I was at Peradeniya; but 
shortly before the break of the rains I found specimens (probably 
Schizomus crassicaudatus) on a very dry slope afew yards away 
from a little stream. A specimen of S. pervadeniyensis subse- 
quently lived in a corked tube in Calcutta without food or water 
for about three months. When a drop of water was placed near it 
by means of a fine pipette the soil was so dry that it was some 
time before the water began to be absorbed, but the Schizomus, 
after examining it carefully with the mobile tips of its antenni- 
form legs, took no further notice, and made no attempt to 
drink. 
I have only once seen a Tartarid take food. On this occasion 
a minute white centipede (Scutigerella) was seized by the second 
pair of appendages in much the same way as a fly is seized by the 
chelicerae of a spider. When secured it was carried off into a 
burrow to be eaten. 
On one occasion I put two specimens (both female) of S. 
peradentyensis in a tube partly filled with soil, and two of S. 
vittatus in another. Before very long the individuals of both pairs 
were found to be facing each other, their antenniform legs 
extended obliquely forwards, those of the one crossing those of the 
other. This futile hostility continued for several hours, after 
which the specimens were separated. Apparently neither dared 
either to attack the other from in front, or to leave her rear 
unguarded for a moment. When, however, a larger number of 
specimens are similarly confined, but on the slippery glass bottom 
of a tube without any soil, they frequently become panic-stricken 
and then attack each other in the same way as they attack their 
natural prey. But even a large number of specimens may safely 
be collected together in a tube when loose soil is provided for them 
to run about on. 
When touched from in front Schizomus usually tries to escape 
by giving a sudden jump backwards. The stink-glands are no 
doubt used for defence; and when a number of specimens are . 
caught and put together in a tube they may be observed to emit 
a distinct odour of acetic acid. 
The chelicerae and second pair of appendages, besides being 
used for offensive and defensive purposes, are used for cleaning 
the feet; and the form of the second appendages allows them to
