Eee Records of the Indian Museum. [Vou. VII, 1912.| 
The chelipedes are unequal in the adult male, but not 
markedly so; in the female the disparity is but slight. The 
merus and carpus, particularly the former, are squamulose on the 
upper surface, while the hand is practically smooth ; the spine at 
the inner angle of the carpus is well developed. The fingers in 
adult males are shorter than the palm, and somewhat unevenly 
toothed ; they gape slightly when closed, while their tips are 
horny and somewhat blunt. 
The legs are a little longer than the smaller cheliped, and their 
joints, particularly the three terminal ones, are beset with rows 
and tufts of setose hairs. The dactyli are armed, above and 
below, with yellow setose spines, a few of which are also seen on 
the propodi. 
The colour of recent spirit specimens is bronze green above, 
with the undersurface and chelipedes yellowish. The distai 
halves of the fingers are pale brown. 
Dimensions of the carapace in a male :—length 13 mm. ; 
breadth 17 mm. ; depth 6 mm. ; width of front 6°55 mm. Dimen- 
sions of carapace in a female (the largest specimen taken) :— 
length 16 mm. ; breadth 21 mm. ; depth 9 mm.; width of front 
8 mm. 
This species can be readily distinguished from the other 
species which Alcock (Catalogue of the Indian“ Decapod Crustacea 
in the collection of the Indian Museum, part I, fasciculus II, 
p. 109, 1910) assigns to his subgenus Liotelphusa. In L. levis 
(Wood-Mason) from Assam, the carapace is more convex, the 
post-orbital crest is fainter, and the post-frontal groove shal- 
lower; the ischium of the external maxillipeds is longitudinally 
grooved, and the length of the sixth segment of the male abdomen 
just equals its distal breadth. From L. austrina, Alcock, the only 
species hitherto known to occur in Southern India, with which it 
agrees as regards the long sixth abdominal segment in the male, 
it can readily be differentiated. In L. austrina, the front is dis- 
tinctly bilobed, and the post-orbital crest is very faint, while the 
ischium of the external maxillipeds is longitudinally grooved. In 
Phricotelphusa campestris, Alcock, from Bengal, there is a similar 
arrangement of the epigastric crests, but in this species the exopod 
of the external maxilliped has no flagellum. 
Locality.—I obtained nine males and eleven females, one of 
the latter with young in the abdominal pouch, from a stream near 
Kavalai, in the Cochin State Forests, last October. The locality 
is situated at an elevation of about 1,000 feet above sea level. 
They were living under stones at the side of the stream, in com- 
paratively dry places, and few were actually observed in the water. 
Paratelphusa (Barytelphusa) jacquemonti, (Rathbun) was com- 
mon in the same stream, but this crab was only seen in the 
water. 
The type (Crustacea Reg. No. 4“) is preserved in the Indian 
Museum.
