The five or, perhaps, even six sj)ecies, known to me personally in 
Queensland and New Sonth Wales are briefly distinguished as follows^ : — 
Phillipsia dnhia, 'Etheridge? — PL XXI, Pigs. 1-1. Glabella long, more 
or less ])yriform, impinging on the anterior border of the shield. 
Pygidinm generally triangular ; thoracic axis narrow and broad, 
18-20 segments. 'Neio South JVales and Queensland. 
Phillipsia Woodwardi, Eth. fit. — Glabella broad and round, separated 
from the anterior border by a deep cbannel, (?) surface pustulose. 
Pygidium unknown definitely. Queensland. 
Phillipsia grandis, Eth. fit. — PI. XXI, Pig. 5, and Photo-lith No. 5 p. 5 
Glabella unknown. Pygidium very large, semicircular, and 
generally and gently convex ; axis broad, about fourteen segments. 
New South Wales and Queensland. 
Phillipsia, sp. ind. (a). — PL XXI, Pigs. 6-8. Glabella unknown. 
Pygidium more or less oval with the general characters of P. 
grandis, but much smaller, and Avith a larger number of segments 
in the axis. New South Wales, and possibly Queensland. 
Phillipsia, sp. ind. [b). — PL XXII, Pig. 14. Glabella unknown. Pygi- 
dium Avith the general characters of the last, and P. grandis, but 
the segments ornamented with toaa^s of very minute pustules. New 
South Wales. 
Griffithides Sweeti, Eth. fit. — Glabella rounded and pustulose, the basal 
lobes A^ery prominent, and supplementary ones at the distal ends of 
the neck segment. Axis of pygidium Avith from 12-14 segments. 
Queensland. 
I am not aware that any Carboniferous Trilobite has been described 
from West Australia, but our collection has been enriched by the impression of 
a pygidium, apparently a Phillipsia, presented by Mr. Connelly, purporting to 
come from twenty-five miles w^est of CoerdaAvandy and the Yaltra Mountains, 
Gascoigne Piver, but the matrix does not correspond with that of other 
fossils from the same locality. On the contrary, it is highly ferruginous and 
^ The Queensland Trilobites will be found described in a work, now passing through the press, by Mr. R. 
L. Jack and the AVriter, “ The Geology a»d Pah-eontology of Queensland and New Guinea ” (Government Printer, 
Brisbane). See also the additional Griffithides, p. 130.
