region is constricted. The rostrum is moderately prominent, the frontal 
lobes very small and subacute. On the cardiac region is a bilobated 
prominence, which is usually very much elevated; there is a small 
angulated prominence on the hepatic regions, and occasionally one or 
two granules on the branchial regions, which are not at all convex. 
Eye-peduncles with a blunt tubercle in the middle of their anterior 
margins. The merus-joints of the outer maxillipedes are narrowed and 
subacute at their distal ends, where they are articulated with the next 
joints. The chelipedes (in both sexes) are rather slender ; margins of 
the arm, wrist, and palm usually with a few granules or spinules ; 
merus somewhat trigonous ; fingers as long as the palm, and somewhat 
incurved, with their inner margins denticulated, and having between 
them when closed (in the males) a small hiatus at base. The ambu¬ 
latory legs are slender, filiform, and very much elongated, the second 
legs being, in an adult male, four times as long as the postfrontal por¬ 
tion of the carapace ; the dactyli of the two posterior pairs only are 
distinctly falciform; both chelipedes and ambulatory legs are scantily 
clothed with long hairs. Length of carapace (including rostrum) of an 
adult male about 5 lines (10 5 millim.), breadth about 3 lines (6 millim.); 
length of second leg about 1 inch 8 lines (42 millim.) ; an adult female 
has the carapace relatively somewhat broader, length nearly 5J lines 
(12 millim.), breadth 4 lines (8*5 millim.). 
The bilobated prominence on the cardiac region and tuberculated 
ej'e-peduncles serve to distinguish this species.” (Miers). 
This species is included in the Indian Fauna on the authority of 
Professor Henderson: there are no specimens in the Indian Museum 
collection.

I agree with Ortmann in placing this genus among the Achseus- 
like Maiidae : the position of the external genitalia of an ovigerous 
female in the Museum collection is conclusive. 
Carapace elongate-subpentagonal, not depressed. 
Eye-stalks long, slender, salient, non-retractile : no orbits or pre¬ 
ocular and post-ocular spines. Antennules longitudinally folded beneath 
the rostrum. 
Antennae long, exposed, dorsally, in the greater part of their extent: 
the basal joint slender, but so short as hardly to reach the front.
