138 Curcinological Fauna of India. 
wrist and also along the upper border of the hand: all these dentations 
tend to disappear with age, but two tubercles at the distal end of the 
outer surface of the wrist are persistent. 
The last two pair of legs are about equal in length, being hardly 
half as long as either of the first two pair: their propodites are much 
shortened and their dactyli are claw-like, forming chele with the 
opposing spines at the end of the propodites. 
Abdomen of male with a broad convex ridge down the middle 
line. 
Sternal tubercles of female very prominent. 
Iu the Indian Museum are specimens from the Persian Gulf, 
Malabar coast (28 to 49 fms.), Ceylon, Coromandel coast, Orissa coast 
(25 fms.) and Gulf of Martaban (67 fms.)—also 2 from Mauritius. 
The largest specimen, from Mauritius, is 5$ inches across the 
carapace. 
Distribution : Indo-Pacific Seas from the Red Sea, Mozambique, and 
Mauritius, to Japan. 
5. Dromia cranioides, de Man. 
Dromidia cranioides, de Man, Journ. Linn. Soc. Zool., XXII., 1887-88, p. 208, 
pl. xiv. figs. 6-8. 
Carapace etc. tomentose. Carapace globose, a little longer than 
broad, perfectly smooth except for the “cervical” groove and for two 
small faint elevations side by side just behind the front. 
Front cut into 3 teeth, the middle one of which is so small and on 
a plane so much lower than the others that it is hardly seen in a dorsal 
view. 
A strongly marked acuminate tooth near the middle of the upper 
border of the orbit is equivalent to the inner supra-orbital angle of 
higher Brachyura. Sub-orbital lobe dentiform, very prominent. Outer 
orbital angle well defined, dentiform. 
True antero-lateral borders of the carapace cut into 3 or 4 teeth ; 
when 4, it is by intercalation of a little tooth close to the base of the Ist. 
A tooth, but not a strongly pronounced one, at the outer angle of the 
buceal cavern. : 
Postero-lateral borders slightly convergent, with one tooth placed 
immediately behind the branchial or “ cervical ” groove. 
Borders of arm granular. or obtusely denticulate, as also are the 
upper border of the wrist and of the hand: two tubercles at the distal 
end of the outer surface of the wrist. 
The last two pair of legs have aclaw-like dactylus which meets, in 
a cheliform manner, a spine at the end of the corresponding propodite.
