P. stanveUensis is so different from all foreign and other Aus- 

 tralian species that it is not necessary to detail its relationships 

 with them. 



The outstanding features of the species are. 1. The dunce's 

 hat-shaped, prominent, smooth and anteriorly drooping, and 

 narrow glabella. 2. The slightly elevated glabellar basal lobes. 



3. The moderate size, and fine but distinct faceting of the eyes. 



4. The very prominent axis. 5. The shallowness of the medial 

 furrows, and slenderness of the ridges of the pleural segments. 

 6. 'J'he bifurcation of the pleural segments of the pygidium. 7. 

 Twelve and eight divisions in the axis and pleural segments, 

 respectively, of the pygidium. 8. The equality of the lengths of 

 head and pygidium.

Sp. Chars. — What appears to be a portion of a cephalon of 

 this species is preserved on a rock-fragment from near Mt. 

 Morgan, Queensland, associated with a very nearly perfect 

 pygidium, free cheeks, a small portion of the anterior of the 

 glabella, and the greater part of the hypostome (m situ), but so 

 little of the glabella remains that none of its features can be 

 recognised; except that it was sparsely granulated, sloped gradu- 

 ally anteriorly, and was of unusual size. The hypostome was 

 large, striated, and apparently granulated; free cheeks very large, 

 strongly granulated, the granules in many instances joining and 

 producing rugosity; posterior furrows very wide and shallow; 

 lateral border very wide; and the undersurface bearing six or 

 seven concentric stride, posterior border narrow; the genal angles
