carapace, though here the grooves between the areole are shallower than in 
the anterior part; (>) by the longitudinal division of areole 2M; (c) by the 
less spiniform character of the armature on the antero-lateral regions of the 
carapace and the frontal margin ; (d) the tubercles of the chelipeds are not 
spiniform as in C. sprnipes, but are much as in Alcock’s figure (Alcock, 1899 
(3), PI. 37. fig. 7) of C. wood-masoni, though less numerous on the larger hand; 
(e) the hands of the are subequal in C. arabica and the tubercles of their 
outer surfaces arranged in more definitely separated straight lines (see figs.) ; 
(7) the armature of the dorsal margin of the carpopodite and propodite of 
the walking-legs is less spiniform than in C. spinipes (PI. 48. figs. 3 a-3 d), 
more as in Alcock’s figure of C. wood-masoni. It will be noted that in (d) 
and (f) C. wood-masoni differs from C. spinipes in the direction of the new 
species. Characters in which the new species approaches C. spinipes and 
C. wood-masoni include the type of granulation of the anterior portion of the 
carapace, the arrangement of the sete of the walking-legs, and the almost 
naked character of the carapace. 
An interesting character in all species of Chlorodopsis is the form and 
relation of the basal antennal joint. In this, which has been described above, 
the new species differs a good deal from both C. areolata and C. spinipes 
(A. Milne-Edwards, 1873 (1), pl. 8. figs. 8 & 6a), and has much the same 
appearance as in three specimens of C. pilumnoides from Ceylon which I have 
before me (recorded by Laurie, 1906, p. 406). 
The new species fal!s under section I. of Alcock’s key to the Indian species 
of Chlorodopsis (Alcock, 1898, p. 165), becoming thus associated with 
C. areolata, from which it is distinguished as above. 
Type specimens are in the British Museum.

Remarks. Except as regards the denticulation of the frontal margin, all the 
specimens fall fairly well under Alcock’s description of C. spinipes. 
One may note in particular :— 
(a) In all cases the first tooth of the antero-lateral border of the carapace 
is much reduced as compared with those following it. This is the case in 
C. spinipes. 
(b) In one example, specimen 226, there is a minute spinule about half- 
way along the posterior border of the second antero-lateral spine of each side; 
this is absent in the other examples, where the condition is as in C. spinipes.
