8p. Char. — Cephalic shield and thorax unknown. Pygidium very 
large, one inch three-eighths broad, and one inch one-eighth long, semi-circu- 
lar, gently convex ; axis broad, tapering rapidly, segments about fourteen ; 
pleura3 very gently convex, along the anterior edge as wide as the axis, the 
ridges of the coalesced segments reaching the margin of a narrow, steep limb. 
Test apparently uuornamented. 
Ohs. — Judging from the relative proportions of thorax, pygidium, and 
cephalic shield in PhilUpsia duhia, the present pygidium must represent a 
Trilohite nearly three inches in length, an exceedingly large size for a Car- 
boniferous form ; unfortunately, the pygidium is the only part known, and 
in consequence the generic identity must for the present remain in doubt. 
Ill all probability the nearest species to this in size is PhilUpsia major , ' 
Slmmard, of which Vogdes^ gives the following ineasurements : — “ M'idth of 
pygidium, inch ; length, lro%-” 
Fig. S. 
The late Mr. C. S. Wilkinson collected a fragmentary pygidium (PI. 
XXI, Pig. 5) near Mount Morgan, one inch in length, as preserved, which 
probably indicates the presence of this species in Queensland.
