side of the line. The cheeks are as much arched as 

 the glabella, and they appear from impressions left by 

 casts to be deeply striated. On the anterior portion of 

 the cheeks, at their greatest convexity, the elevated pe- 

 dunculated eyes are located; they are small, and club 

 shaped. 



The cervical and occipital furrows are deep and wide. 

 The occipital ring is marked by four tubercles.

The general form of the cephalic shield is semilunar, 

 its width is twice its length ; the marginal border (lim- 

 bus) is wide and thick, the posterior angles being short 

 and obtuse. The moderately convex glabella is marked 

 with three furrows, which do not extend across it ; from 

 the base of the glabella to the first furrow its form ia 

 nearly cylindrical, and from this furrow towards the 

 front it is clavate. The prominently arched cheeks are 

 separated from the glabella by deep and wide dorsal 

 furrows ; the eyes are small and pedunculated, inclin- 

 ing to the front. The surface of the head is covered 

 with large tubercles. 



The facial sutures commence on the outer margin, 

 some little distance above the posterior angles, and run 

 obliquely to the eyes ; they then converge towards the 

 front of the glabella, and afterwards to the outer mar- 

 gin. The occipital ring is greatly convex. 



The thorax consists of 12 segments, and has marked
