I9g15.| J. R. HENDERSON: Hermit-Crabs from Chilka Lake. 27 
Eyestalks distinctly longer than the anterior border of the 
carapace and almost as long as the antennular peduncles; the 
eye occupies about one-tenth of the length of the stalk. Oph- 
thalmic scales with the outer edge setose and faintly spinose. 
Antennal acicle setose and slightly spinose, the proximal 
spinule being most prominent, scarcely reaching the terminal 
joint of the peduncle; flagellum about one and a half times as - 
long as the carapace. 
Chelipeds subequal and similar; merus with the upper 
margin obscurely serrulate and two spinules at the distal end of the 
outer lower margin; carpus with a distinct spinule at the distal 
end of the upper margin and two or three smaller spinules further 
back on the margin; hand only slightly roughened and compara- 
tively free of setae, with no spines anywhere on its palmar 
surface ; fingers rougher and more setose than the palm, the projec- 
tions almost becoming spinose towards the finger-tips, when closed 
exhibiting an intervening hiatus. The length of the hand, includ- 
ing the fingers, is about twice its breadth. 
The second and third legs exceed the chelipeds on both sides 
by the length of the dactyli and nearly half the propodi; a 
spinule is present at the lower distal end of the merus and 
another at the upper distal end of the carpus in both pairs of 
legs. The dactylus of the third leg is about one-fourth longer 
than the corresponding propodus; the dactylus of the second leg 
while shorter is still distinctly longer than its propodus. 
The colour of spirit specimens is yellowish, with the chelipeds 
and second and third pairs of legs olive green. The only distinct 
bands of colour are three pale red lines, on the inner upper and 
outer surfaces of the eyestalks, though in the specimen from sta- 
tion 142 the upper line is obsolescent. The meral and carpal joints 
of the second and third legs, particularly the former, show a faint 
bluish green colour near the upper posterior surface and a reddish 
brown tinge near the lower margin, but these colours are not 
sufficiently circumscribed to constitute bands. ‘The dactyli of the 
second and third legs are buff-coloured. 
Length of carapace (in a male) 12 mm., breadth of anterior 
border of the carapace 4mm., length of eyestalk 5°5 mm.,length of 
dactylus of second left leg 9°5 mm., length of propodus of second 
left leg 75 mm. The left eyestalk of the type specimen is shorter 
than the right and is evidently in process of regeneration. 
This species is closely related to C. padavensis, de Man, and 
C. longitarsis (de Haan), both of which commonly occur in brack- 
ish water inIndia. It agrees with them in the long dactyli of the 
second and third legs, and in the long eyestalks, which are longer 
than the anterior border of the carapace, but is readily distin- 
guished from both by its colouration. 
In C. padavensis', there are very distinct deep red or
