The carapax is not suddenly narrowed at the bases of the antenne, 
where the breadth is equal to the length in front of the cervical suture, 
and not rostrated, the median lobe of the front being broadly rounded 
and not projecting as far forward as the external angles of the orbital 
sinuses, which are acute and each usually armed with a short spine. 
The eyestalks, including the eyes, are nearly four-tifths as long as 
the breadth of the carapax in front, stout, and expanded at the very 
large black eyes, which are terminal, not oblique, compressed vertically, 
and broader than half the length of the stalks. The ophthalmic scales 
are small, narrow, and spiniform at the tips. 
The peduncle of the antennula is about as long as the breadth of the 
carapax in front, and the ultimate segment about a third longer than 
the penultimate. The upper flagellum is much longer than the ultimate 
segment of the peduncle, while the lower is only about half as long as
