which border is serrulate not entire; in having small spines opposed 
to the dactyli—at the end of the propodites of the last two pair of 
legs; and in being more granular.

Differs from Dromza in the following particulars :— 
The carapace is more elongate: the efferent branchial channels 
are defined by ridges. 
The fourth (last) pair of legs are as long as, or even longer than, 
the first two pair. 
The sternal grooves of the female end in two tubercles placed close 
together near the bases of the chelipeds. 
The front is variable: it may be cut into 3 teeth as in most species 
of Dromia, or may be bilobed, or may consist of a single triangular 
tooth. 
Distribution: Cape of Good Hope, Seychelles, Indian Seas. 
N. B.—In Dromia cranioides, Dromia unidentata and Cryptodromia tuberculata 
the last pair of legs are very little shorter than either of the first two pair. . 
Key to the Indian species of Pseudodromia. 
I. Front cut into 2 teeth, each of which isfused at base with 
the tooth of the prominent supra-orbital margin; so that 
the front appears to be formed of two divergent lobes each 
of which has both its angles acutely produced ... P. quadricornis, 
II, Front in the form of a single triangular tooth ... .. PP. integrifrons. 
15. Pseudodromia quadricornis, n. sp. ? 
Perhaps identical with “‘ Homalodromia” Coppinger, Miers, loc. cit. pl. L. fig. B. 
Carapace etc. tomentose: a line of peculiarly long silky hairs forms 
a fringe or false anterior border to the carapace, behind the deflexed 
front. 
Front deflexed, dorsally grooved in the middle line, cut into two 
broad teeth, each of which is fused at base with a broad supra-orbital 
tooth ; so that the front appears to consist of two large lobes, each of 
which has its anterior edge concave and its antero-lateral angles acutely 
produced. 
Carapace in the adult longer than broad, slightly convex from side
