Henderson, Trans. Linn. Soc. Zool. (2) V. 1893, p. 406. 
Carapace etc. with a short velvet-like tomentum. 
Carapace not quite as long as broad, only moderately convex, its 
surface smooth, its -regions very fairly indicated: the “ cervical” 
groove is distinct, the fronto-orbital region is marked off by a shallow 
transverse groove that runs from one antero-lateral angle of the 
carapace to the other, and the front itself is longitudinally grooved. 
Front cut into 3 broad triangular teeth of nearly equal size, the 
middle one nearly horizontal, but on a much lower plane than the 
others, which are somewhat upcurved. 
A tooth near the middle of the upper border of the orbit marks the 
position of the true inner supra-orbital angle. Outer orbital angle 
dentiform, Infra-orbital lobe dentiform and prominent. 
True antero-lateral borders with 2 teeth: in the concave space 
between the lst (large) tooth and the outer orbital angle a stout sub- 
hepatic tooth shows up: below this again is a tooth at the outer angle 
of the buccal cavern. 
On the postero-lateral border, immediately behind the branchial or 
“ cervical” groove, is a tooth. 
Outer surface of wrist nodular: a few nodules on upper border of 
palm : fingers short and stout. 
The carpus and propodite of the first 2 pair of legs are nodular. 
Last 2 pair of legs short and slender, not nodular, not much more 
than half the length of the first 2 pair: the 4th (last) pair very little 
longer than the 3rd. Both end in a strong claw-like dactylus, but are 
hardly cheliform, although there is a small spine at the end of the 
propodite of each. : 
Abdomen of male with a convex ridge down the middle line. 
In the Indian Museum are 2 males and a female, from the Anda- 
mans and the Persian Gulf. 
The carapace of the largest specimen is 14 millim. long. 
Distribution : Indo-Pacific Seas from the Red Sea and east coast of 
Africa to Japan. 
9. Dromia (Cryptodromia) bullifera, n. sp. 
Carapace etc. covered with a short tomentum. 
Carapace about as long as broad, convex, smooth, ‘cervical ” 
groove shallow but distinct. 
Front cut into 3 acute rather slender teeth, the middle one of 
which is on a lower plane and is slenderer than the others. 
An acute spine near the middle of the upper border of the orbit
