The whole dorsal surface of the animal is smooth and polished. The carapace is 
strongly convex from side to side and is almost as broad anteriorly as posteriorly. 
There are no carinae on the carapace. The gastric grooves are sharp and distinct, 
but the cervical groove is obsolete and is represented merely by a short and shallow 
depression on the outer side of the gastric. The lateral margins are convex, the antero- 
and postero-lateral angles are rounded and the posterior margin is deeply concave. 
The rostrum (fig. 86) is broader than long, cordiform and widest at a point sonte- 
what in advance of its proximal end. ‘The lateral margins are not upturned and con- 
verge rapidly to an acute, but rounded, apex behind which they are often slightly con- 
cave. The dorsal surface is smooth except for a blunt longitudinal carina in the 
anterior third. 
The eyes are large. The breadth of the cornea is about equal to the greatest length 
of the cornea and stalk combined, and the corneal and peduncular axes are very oblique. 
On its outer margin the eyestalk bears a small but not inconspicuous tubercle. The 
anterior margin of the ophthalmic somite is sharply pointed, and its dorsal processes 
consist of a pair of upstanding lobes which terminate subacutcly on either side of the 
rostral apex.
