This species has been so well clescrihecl and illustrated hy both Eletcber 
and Salter that I feel I need not enter into a detailed descri|)tion of the 
distinguishing characters, the principal and most easily remembered of which 
is the longitudinal arrangement of five or six small tubercles which ornament 
the median region of the axis of the pygidium. The glabella is hut feebly 
inflated, thick and ornamented with tubercles, of which the anterior are a little 
larger than the others, and are arranged in an arc on the edge of the limb. 
The glabella-furrows are faintly marked, and from the arrangement of the 
tubercules it is hard to define their presence. The genal spines are pointed, 
but not very long. The eye is small and supported on a projecting tubercle, 
the sides of which bear several delicate radiating folds trending towards a 
similar number of small tubercles arranged around the base, while the inner 
portions situated above the facial suture are covered with large tubercles.
