enumerates seventeen Indian species, to which he supplies 
a valuable key or synoptic table. As not uncommonly happens 
when the species of a genus are numerous, the definition 
varies somewhat with the date, and is so to speak encrusted 
with alternative characters. Miers in 1876 spoke of the 
front as ‘“‘not produced beyond the level of the orbits,’ but 
this is unsuitable to the type-species. In 1886 he says, ‘‘ The 
post-abdomen in the male is five to seven-jointed.” But 
for this should probably be read, “in the male five, in the 
female seven-jointed,” in accordance with his own earlier 
statement, and with that of Paulson and Haswell. Alcock 
more explicitly writes, “Abdomen of the male five-jointed, 
somites 3, 4. 5 fused.” He adds that the species are ‘‘ small 
crabs, distinguished by the elaborate lobulation of the carapace, 
and by the form of the front, which is usually deep-cleft in 
the middle line to form two prominent round-pointed lobes. 
In the type species the lobes of the front are irregularly rounded 
but scarcely seem to be in any sense pointed. The lobulation 
of the carapace is a more striking than distinctive feature, 
since unfortunately it is shared by other genera such as Daira. 
The latter genus, however, is well marked by the peculiar 
notch in the front margin of the third maxilliped’s fourth 
joint.
