A. Alcock — Carcinological Fauna of India. 
[No. 2, 
anterior border cut into four or five teeth, of which the first, or external 
orbital angle, is small and pointed, the second larger et a extremite 
mousse , and the others successively smaller. The rostrum consists of 
two short stout spines, and the supra-ocular border forms a spine. 
Chelipeds short: fingers evenly toothed. Ambulatory legs ending in a 
recurved claw. The abdomen of the male consists of 5 segments, the 
2nd, 3rd and 4th being fused together. 
There are no specimens of this species in the Museum Collection, 
which is included in this Fauna on the authority of Dr. Heller who 
mentions it in the ‘ Novara ’ Collection, from Madras. 
The genus or sub-genus Soyramathia has, I think, very close affinities 
with the genus Pugettia , and is certainly, I think, a close link between 
this sub-family and the following. 
Sub-family iii. PISINHQ. 
Eyes with commencing orbits, of which one of the most character¬ 
istic parts is a large, blunt, usually isolated and cupped post-ocular 
tooth or lobe, into which the eye is retractile, but never to such an 
extent as to completely conceal the cornea from dorsal view: there is 
also almost always a prominent supra-ocular eave, the anterior angle 
of which is sometimes produced forwards as a spine. Eye-stalks short. 
Basal antennal joint broad, at any rate at the base; its anterior angle 
generally produced to form a tooth or spine. Merus of the external 
maxillipeds, owing to the expansion of its antero-external angle, broader 
than the ischium, and carrying the palp at its antero-internal angle, 
Rostrum two-spined (in Doclea obscurely so). Legs often very long. 
Fey to the Indian Genera. 
Alliance 1. Pisoida. Supra-ocular eave not in close contact with the post¬ 
ocular spine or process, and generally produced, but not very conspicuously, at the 
antero-external angle in the plane of the rostrum. 
'"1. Post-ocular tooth either not cupped, or 
if cupped then the carapace is armed 
with long acute spines of uniformly 
large size and regular arrangement. Scyramathia. 
I. 
Spines of the ros¬ 
trum separate 
from the base, 
usually long and 
divergent. 
2. Post-ocular tooth 
deeply cupped; 
spines of the ca¬ 
rapace, if present, * 
never of uniform 
size and arrange¬ 
ment. 
i. Spines of the ros¬ 
trum bearing a 
secondary spinule, 
either at tip or 
somewhere in their 
distal half . 
ii. Spines of the ros¬ 
trum without a 
^ secondary spinule 
Naxia. 
Hyastenus.
