Oater surface of carpus and propoditc of first two pair of legH 

 uneven but not distinctly nodular. 



Last 2 pair of legs sliort, ending in claw-like dactyli, not chclifoim ; 

 the 3rd pair shorter than the 4th. 



A single small specimen from Mergui (Anderson collection). 



11. Dromia (Gryptodromia) Hilgendorfi, de Man. 



Cryptodromia Hilgendorfi, de Man, Archiv. £. Naturges. LITI. 1887, i. 404, 

 pi. xviii. fig. 3. 



Carapace etc. with a short velvet-like tomentum. 



Carapace longer than broad, convex, smooth, without distinction 

 of regions. " Cervical " groove broad and shallow. 



Front cut into 3 teeth, the lateral ones broad and triangular, the 

 middle one so small and deflexed as to be hardly visible in a dorsal 

 view. 



There is no distinct tooth in the upper border of the oi-bit, but 

 only an angular bulge, to mark the position of the inner supra-orbital 

 angle. Outer orbital angle and snb-orbital lobe not dentiform. 



The antero-lateral borders of the carapace are smooth and entire, 

 but as they bend sharply inwards towards the orbits their anterior 

 angle forms a forwardly-directed tooth, the space between which and 

 the outer-orbital angle is concave. 



A very small prominence on the postero-lateral border, just behind 

 the branchial or " cervical " groove. 



The chelipeds and legs have an uneven surface, but are not really 

 nodular, though both the inner and outer angles of the wrist are 

 strongly pronounced. 



The last 2 pair of legs are short and slender, the 4th (last) pair 

 being very little longer than the 3rd; both end in stout claw-like 

 dactyli but are not at all cheliform. 



The abdomen bends in very sharply from the 4th segment, making 

 the under surface of the body very flat. 



In the Indian Museum are a male and a female from the Persian 

 Gulf. 



The carapace of the larger of the two is 12 millim. long. 



Distribution : Indo-Malayan coasts. 



12. Dromia {Cryptodromia) ehalioides, n. sp. 



Carapace hardly at all tomentose : a few hairs on the borders of 

 some of the leg-joints. 



Carapace subcircular with projecting front, convex, its surface 

 closely and crisply granular : not only are all its regions very distinct
