probably prevail. Specimens from any one of these localities 
appear to exhibit a much smaller range of variation than the 
species as a whole, their extremes scarcely, indeed, overlapping. 
The fact that this much variation does, however, occur, and 
that specimens from other localities in the same neighbourhood 
may ultimately be proved to show similar ranges of variation 
which overlap extensively, seems to render it improbable that the 
Trichur form ought to be recognized as a definite race worthy of 
a subspecific name. 
Phrynichosarax javensis, n. sp. 
(Plate xxxi, fig. 3.) 
Only one specimen is known to me. It is from Buitenzorg. 
It differs from P. cochinensis only in the minuteness of the spine on 
the finger (see pl. xxxi, fig. 3) and in the 4-jointed hind tibiae. 
The 4-jointed tarsi suggest that a larger series would be not un- 
likely to show that the hind tibiae were normally 3-jointed as in 
other members of the genus. 
The carapace is 3°2 mm. broad by 2'2 mm. long in the middle 
line. The femora of the antenniform legs are 4°8 mm. long, 
those of the first walking legs 2°99 mm. 
Phrynichosarax buxtoni, n. sp. 
(Plate xxxi, fig. 4.) 
Two specimens (one immature) were collected by Mr. B. H. 
Buxton in Kubang Tiga cave, Perlis, Malay Peninsula. 
The carapace is heart-shaped. In the mature specimen ( @ ) it is 
4°I mm. broad by 3°3 mm. long in the middle line. Behind the lateral 
eyes it is bordered by a broad horizontal ledge. The fovea is 
deeply impressed, continuous with a pair of large lateral grooves 
directed slightly backwards, and with a short median groove behind 
it. In an anterior median groove, about two-thirds of the way from 
the fovea to the eye, is a hollow somewhat smaller than the fovea, 
with which, and with two pairs of lateral depressions together en- 
closing a rectangle, it forms an almost regular hexagon. The 
anterior sides of this hexagon are, however, a little longer than 
the posterior, and these than the lateral. A radial groove extends 
outwards and a little forwards from each member of the two pairs of 
lateral depressions, and between the posterior of these grooves and 
the lateral grooves connected with the fovea is a pair of short grooves 
extending from the margin about half way to the fovea. A single 
line of tubercles runs from the fovea outwards and backwards to- 
wards the margin between the last-mentioned grooves and those 
immediately behind them. ‘The rest of the surface is ornamented 
with less definite bands and patches of tubercles. 
The arms are short and stout. The proximal dorsal spine of 
the hand is little more than half as long as the distal; there is a 
somewhat shorter spine on the ventral margin. Even the ventral 
of the spines of the hand is, however, longer than either of the two
