jargonelle, and I regret that I have not made notes of the scents 
of the various species. 
Mr. H. N. Ridley has sent me several specimens of Thelypho- 
nus linganus. He compares their defensive odour to that of 
chlorine gas, and says he knows of no other animal able to emit so 
widely diffused and powerful an odour for its size. This species eats 
crickets, woodlice, etc., and Mr. Ridley once found a specimen eating 
a cricket in the day-time, though usually the species is nocturnal. 
The modification of one or more of the sixth to eighth tarsal joints 
of the antenniform legs of the female of this and allied species of 
Thelyphonus is perhaps due to the development of special organs 
for use during courtship; for it is at about this point that these 
appendages are held in the chelicerae of the male during that 
process in the only species of Thelypionus in which it has been 
described. 
The odour emitted by Uroproctus assamensis resembles essence 
of jargonelle. This species lives in a damp region, and does not 
seem able to withstand drought in the way that Thelyphonus 
sepiaris can. 
Mr. G. Mackrell tells me that Hypoctonus oatest exudes a fluid 
smelling like acetic or formic acid, though perhaps a little more 
pungent. It inhabits country where stones are not to be found, 
living in the banks of roads and cuttings and in the vacated burrows 
of ants. In June specimens usually have to be dug out from a 
depth of about 18 inches, but in August they are often found at 
the entrance of their holes. On one occasion two females were 
found in a nest swarming with ants. Both had young clinging to 
their abdomens. 
I have found several species of Hypfoctonus under stones in 
Burma. I have not been able to study their habits in captivity, 
but there seems every reason to believe that they are very like 
those of Labochirus proboscideus and Thelyphonus seprarts. 
I do not think any of the Thelyphonids I have studied can 
be luminous as suggested by Sorensen (Ent. Med. 1894, pp. 175- 
177); and I can hardly believe that the sting described by Flower 
(Journ. Straits R. Asiatic Soc., July 1907, pp. 38-39) was really 
due to the Thelyphonus schimkewitchi that he was handling when 
he received it. I have handled other species frequently without 
receiving any harm. 
Schizomidae (Tartarides). 
The only species which I have myself found in any abundance 
are Schizomus (s. str.) crassicaudatus, S. (Trithyreus) peradeniyensis, 
and S. (T.) vittatus, all from Ceylon, and it is only to these that 
- the following account refers.! The Calcutta form—S. (7.) lunatus 
—I have found under bricks on somewhat moist stiff clay; and so 
| A preliminary note on the habits of these species appeared in Spolia Zeyla- 
nica, VII, p. 46, fig. C. Nothing else beyond a brief note on a species from 
caves near Moulmein (¥.A.S.B. [ns.], IX, p. 417) appears to have been written 
about the habits of Indian species.
