Description.— Dorsal surface smooth and more or less 
polished between the carine. Breadth of carapace behind 
antero-lateral teeth about one-half of its length. Anterior 
margin on either side of rostral plate concave and slightly 
oblique, tips of strong antero-lateral teeth not nearly reaching 
level of frontal edge. 
All carinze of carapace well marked. Median carina 
forked in front and behind; in full-grown specimens it is 
always interrupted just where it divides anteriorly, and in 
some specimens the limbs of the fork are almost obliterated. 
Dorsal pit a little nearer to the frontal margin than to the 
cervical groove ; anterior fork of median carina extending 
not more than two-thirds of the distance from frontal margin 
to dorsal pit. Lateral margin of carapace distinctly angled 
posteriorly,
