The buckler of this species is irregularly hemis- 
pherieal; the front pyriform and without pustula- 
tions. The cheeks are almost entirely occupied by 
the eyes, which are placed very near each other on 
the upper part of the forehead; are very large and 
trilobate, the side lobes being elongated and at- 
tenuated in front. The articulations of the back are 
twenty in number, those of the abdomen not being 
distinguishable from those of the tail. The costal 
arches of the side lobes are round near their extremi- 
ties, and are intersected with two or three raised 
lines. Length nearly four inches. Breadth about 
two inches. |
