I.—Dersorietion oF A New GENUS oF TrInoBitEs, Ovrcoprar 
LIvERSIDGEL, FROM THE SILURIAN OF New Sourn Watzs. 
By Hxnry Woopwarp, LL.D., F.R.S., F.G.S., 
of the British Museum. 
NEW and interesting species of Trilobite having lately been 
obtained by Professor A. Liversidge, F.C.S., F.G.S., of the 
University of Sydney, in the Silurian rocks of Bombala, New South 
Wales, and forwarded to my colleague, Mr. R. Etheridge, jun., F.G.S., 
with a series of other Paleozoic fossils, from Australia, it has been 
obligingly placed in my hands for description. 
I was at first doubtful whether to treat this fossil as a new species 
of Deiphon or as a distinct genus, near to Deiphon and Staurocephalus ; 
but on a further comparison of these forms with Professor Liver- 
sidge’s specimen however, there appear to be such important points 
of difference in the body-segments and pygidium as to entitle it to be 
Onycopyge Liversidgei, H. Woodw.’(restored)! nat. size. Silurian, Bombala, New 
South Wales. 
1 The original specimen is preserved in a black and hard splintery limestone, and 
has been much broken, a part being seen in intaglio and a part in relievo. The 
position occupied by the hypostome in the fossil at the back of the glabella is 
indicated in the woodcut.
