Dromia cranioides, de Man. Plate II., fig. 5. 



Dromidia cranioides, de Man, Journ. Linn. Soc, Zool., XXII., 1887-88, p. 208, pi. xiv., figs. 6-8 : Alcock, 

 .T. A. S. B., LXVIII., pt. 2, 1899, p. 138. 



This species may perhaps prove to be identical with the Dromia incUca 

 briefly characterized by Gray (Zool. Miscell., p. 40). 



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, 

 sub-dentiform. A tooth, Inxt not a strongly pronounced one, at the outer angle 

 of the buccal cavern. 



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 1st. 



Postero-lateral borders slightly convergent, Avith one tooth placed im- 

 mediately 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 a claw-like dactylus which meets, in a cheU- 

 form manner, a spine at the end of the corresponding propodite. The last pair 

 are much longer than the last pair but one, being, in fact, very little shorter 

 than either of the first two pair. 



Abdomen as in D. Enmi^lm. 



The sternal grooves of the female approach one another closely, but do not 

 actually meet, on the segment of the sternum corresponding with the 1st pair of 

 ambulatory (monodactylous) legs, near the anterior end of which segment they 

 terminate, without tubercles. 



The chelipeds carry an epipodite. 



The length of the carapace of the largest specimen is 28 millim., its greatest 

 breadth is 26 milUm.
