The contour of the buckler in this species, cannot 
be satisfactorily determined from our present speci- 
men; the anterior and posterior parts of it are well 
ted or obscured. ‘The front is very much elevated 
above the surface of the cheeks. It rises a little be- 
fore the anterior edge of the buckler ; is rounded in 
front, and gradually tapers towards the middie lobe of 
the abilomen, with which it forms a regular continua- 
tion. On its posterior surface there are three transverse 
furrows ; the upper one crosses it a little obliquely, 
and there is on each side above, a considerable 
protuberance. The cheeks were’ no doubt in, the: 
form of spherical triangles, but whether the outer. an- 
gles terminated in acute prolong ations, cannot from 
our specimen be determined. The organs of vision 
appear to be entirely wanting. There are two shal- 
low depressions on each side of the cheeks, commen- 
cing near the protuberances on the front, and — uae 
ning towards the lateral edges of the buckler.. ‘The 
posterior border of the buckler where it joins the lobes 
of the abdomen, is marked by a transverse groove, 
nearly er with the lower transverse furrow 
, 
on the front; this groove at its commencement ap-
