28 Records of the Indian Museum. [Von. XI, 
crimson lines on the second and third legs, eyestalks and cheli- 
peds. In C. longitarsis, a pale blue band bordered above and 
below by red brown occurs on the joints of the second and third 
legs, being best marked on the propodi, and there are no colour 
lines on the eyestalks or chelipeds These distinctive marks are 
present at all stages of growth, and I am of opinion that colour 
is a fairly reliable character in separating the species of Clibana- 
viUs. 
In addition to the colour differences, the hand of C. olivaceus 
is much smoother and less hirsute on the upper surface, while the 
inner margin is devoid of the spinules which occur in the two 
other species. 
Clibanarius sp. 
Station 82, 8709/10. Five very small individuals which are 
too young to identify satisfactorily. They perhaps belong to the 
last species. 
Diogenes miles (Herbst). 
Alcock, p. 67, pl. vi, fig. 5. 
Ganjam Coast outside the southern part of the Chilka Lake, 
in a Voluta shell, 8706/10. A female with ova in which the 
carapace measures I5 mm. in length. 
This species, which is common on the east coast of India, 
but so far as I know does not affect brackish water, has a charac- 
teristically flattened carapace, and the hand of the left or larger 
cheliped can be bent almost at right angles to the wrist, the result 
of living in shells with a long narrow aperture. 
Diogenes avarus, Heller. 
Alcock, p. 68, pl. vi, fig. 6. 
Station 71, 8703/10. Three small specimens. 
Station 91, 8764/10. Eleven small specimens, including 
several females with ova in which the carapace measures less 
than 5 mm. in length Also 8707/10; two small specimens. 
Station 93, 8701/10. Seven small specimens, one of which, 
a female with ova, has the carapace 5 mm. long. 
Station 94, 8702/10. ‘Two minute specimens. 
This small species is common in the South Indian back- 
waters, but also occurs in the sea, both between tidemarks in 
places such as the shores of the Gulf of Manar where the surf is 
not excessive, and in shallow water. As was first pointed out by 
de Man the lengthening of the carpus and band of the larger 
cheliped, which is so characteristic a feature of adult males, is 
much less marked in females and young males. Some individuals 
appear to attain maturity while of small size; in the present 
collection there are several females with ova in which the cara- 
pace measures 5 mm. in length or even less, while individuals 
from other localities are found at least double this size.
