but they are also areolated, the individual areolas being convex^ suhcir- 

 cular, and particularly well defined. The true cervical groove is present, 

 as well as the branchial groove that generally goes by this name. 



Front longitudinally grooved, cut into 3 serrulated teeth of which 

 the lateral ones are broadly triangular, while the middle one is narrow 

 and is more prominent than the others. 



Upper border of the orbit very oblique, serrulate, devoid of any 

 tooth to mark the inner supra-orbital angle of the higher Brachyura. 

 Outer orbital angle and suborbital lobe not prominent. 



Lateral borders of carapace serrulate, not toothed, though there 

 may be a small granular bulge in front of, and another behind, the 

 branchial groove. 



Legs and chelipeds crisply granular, the chelipeds and first tw o 

 pair of legs being also nodular. 



Last 2 pair of legs very slender, hardly half the length of the first 

 2 pair, ending in hook-like dactyli, not cheliform. 



First four abdominal terga with some symmetrical granular sculp- 

 ture, the other three granular but not sculptured. 



Three specimens, a male and 2 females, from Karachi : the cara- 

 pace of the largest is 7 millim. long and 8 millim. broad. 



This species, and the one following, show the transition to Petalo- 

 meray having a granular carapace, on the dorsal surface of which the 

 true cervical groove is as plain as the branchial groove that is commonly 

 called " cervical." 



13. Dromia (Cryptodromia) Gilesii, n. sp. 



Closely related to D. sculpta, Haswell. 



Carapace etc. without tomentum : a few hairs on some of the leg- 

 joints. 



Carapace pentagonal, convex, its greatest length about equal to its 

 greatest breadth, the greater part of its surface covered with vesiculous 

 granules : not only are all the regions very distinct, but they are also 

 areolated — the areolas* however not being so individually convex as they 

 are in D. ebalioides. The true cervical groove is present as well as the 

 branchial groove. 



Front cut into 3 triangular teeth, of which the middle one is the 

 smallest and is on a lower plane and obliquely deflexed. 



Upper orbital border very oblique : a hardly noticeable angulation 

 — not a distinct tooth — marks the true inner supra-orbital angle. Outer 

 orbital angle not pronounced. Suborbital lobe dentiform but inconspi- 

 cuous. 



Antero-lateral borders of the carapace cut into 5 small granular
