front, on both sides of the front lobe of the glabella ; 

 the facial line, therefore, runs obliquely to the front, 

 from the posterior angles of the head ; this line 

 in C. Wcerthii terminates nearly parallel with the pos- 

 terior margin of tJie ce2:)halic shield ; the eye pedicles 

 on the high arched cheeks are placed alongside of the 

 middle furrow, and not, as is in C. bellatulus, on the side 

 of the large anterior front lobe of the glabella. 



The three glabella furrows are indistinctly marked. 

 Thorax has 12 segments. The sixth segment of the 

 thorax in O. bellatulus extends itself, as Angelin shows 

 it in his plate, and terminates in a very long sharp 

 point. This character is not noted in C. Wcerthii. 



The four segments of the pygidium are wider than 

 long. Length generally about one inch.

Cephalic shield semi-elliptical ; width more than twice 

 the length. Glabella clavate, moderately convex ; the 

 anterior dorsal furrows are irregularly rounded, with 

 a notch in the middle. Occipital margin half the 

 width of thelimbus; cervical furrow extending across. 

 The three glabella furrows on each side extend one- 

 third across; the lobes gradually diminishing in size 

 posteriorly. Fixed cheeks broad, gently convex. Eyes 

 distinct ; located about the width of the glabella from 

 the dorsal furrows, opposite the second lobe, and placed 

 about opposite the last glabella furrow. They appear 

 to be small, and are connected with the front furrow by 

 an ocular ridge. Movable cheeks unknown.
