in the Macleay Musenm, and described by myselfd Either, therefore, a mix- 
ing of fossils has taken place, or a similar glazed ironstone deposit occurs 
in the district collected from by Mr. Connelly. The pygidiiim in question is 
not distinctly preserved, but appears to possess seven or more axial segments. 
The interesting fact now stands revealed that we are unacquainted 
Avitli the occurrence of Trilobites in New South M^ales in any beds that can 
with certainty be referred to the Permo-Carboniferous. So far they are 
wholly Carboniferous.

Sj). Char . — Body elongately oval. Cephalic-shield more or less semi- 
circular ; anterior border flattened, broad, and generally well defined; glabella 
ob-pyriform, slightly convex, and gently attenuated forwards, extending to, 
but not overhanging, the anterior border ; glabella furrows, all three pairs 
visible (in casts), the two anterior pairs short and close together, oblique, the 
anterior pair shortest, and on a level with the anterior termination of the eye, 
the posterior pair almost circumscribing the basal lobes, which are ohlong ; 
palpebral lobes narrow ; neck lobe narrow, not greatly differentiated from the 
glabella, without a tubercle, or sujiplementary distal lobes. Eye large, 
markedly semilunar, and highly facetted. Eree cheeks small, with wide flat 
borders. Genal angles obtuse.' Thorax. — Axis narrow, very convexly 
arched ; angular in the middle line, distal or outer halves bent downwards. 
Pygidiiim large, subtriangular, but varying in degree, axis and pleurae similar 
in character to those of the thorax ; axis narrow, and rapidly attenuating to
