but they are also areolated, the individual areole being convex, subcir- 
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 two 
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- 
mera, 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: afew 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 areola 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
