Phrynichosarax cochinensis, n. sp. 
(Plate xxxi, fig. 2.) 
This species is common under stones in the evergreen jungles 
of the lower slopes of the Western Ghats in Cochin, and it is on 
account of the large number of specimens available for study 
that I have selected it as the type of the genus. The specimens 
were found near Kavalai, on the Cochin State Forest Tramway, 
at altitudes up to about 2500 ft. above sea level; at about 
0-300 ft. above sea-level near the same tramway between miles 
to and 14; and at the base of the hills near Trichur. Specimens 
from the last-named locality differ from the others in that the 
legs (both kinds) tend to be much longer and slenderer, while 
the separation of the first and second joints of the hind tibiae is 
usually obscure or absent. In one specimen, indeed, the right 
hind tibia is entire. 
As type of the species I have selected a female with young 
still adhering to her back in the preserved state. This specimen 
is from jungle beside the lower part of the State Forest Tram- 
way. 
The cavapace is 14 times as wide as it is long in the middle 
line, or may be a little wider; its maximum width is slightly 
over 4mm. It resembles that of P. buxtoni (below, p. 439) in gene- 
ral structure, but is finely and evenly granular throughout, and 
usually looks much broader in proportion to its length. The 
depression in the median groove behind the eyes is less defined, 
although the groove is well developed. The second radial grooves 
of the two sides are united across the middle-line, together forming 
an almost straight line in contact with the anterior part of the 
fovea. 
The arms are always short and stout. The proximal dorsal 
spine on the hand is scarcely as long in proportion to the distal 
as in P. buxtont. There is only one spine onthe finger (see pl. 
xxxi, fig 2) ; it is situated close to the base of the dorsal margin, and 
is about as long as the ventral spine of the hand, which latter spine 
is situated close to the lower distal angle. 
The Jegs are variable in length. ‘The femora of the antenni- 
form legs may be from scarcely 14 to fully 24 times as long as the 
carapace is wide. The femora of the first pair of walking legs 
may be from a little less than, to nearly 14 times as long as the 
carapace is wide. The metatarsi are longer than the tarsi, and 
the first tarsal joint of each leg is longer than are the rest together 
—very slightly so in short-legged specimens and much more so in 
long-legged. The hind tibiae may be more or less distinctly 2- or 3- 
jointed. In one specimen that of the right side is entire, that 
of the left side being 2-jointed. The extent of the jointing of the 
hind tibiae and the slenderness of the legs appears to be corre- 
lated with locality as noted above. All the localities from which 
the species is yet known are situated in one comparatively small 
area, over the whole of which comparatively uniform conditions
