Prom Western Australia, on the other hand, Dr. G. J. llinde lias 
recorded^ a Spirorhis from the rocks of the Gascoyne Diver, helieving it to l)e 
referable to the Devonian S. omphalodes, Goldf. It does not appear to me, 
liowever, that the Devonian age of these rocks is yet snlTiciently v ell proven. 
Amongst the later collections made hy Mr. Cullen were a number of 
Encrinite stems from near Mount Vincent, on which a few microzoa were seen 
adhering. Amongst them was a small loosely coiled Serpula, hereinafter 
described as S. testatrix. 
A few Carboniferous fossils have lately been presented to the Mining 
and Geological Museum l)y Mr. Connelly from twenty-five miles west of 
Coerdawandy, Yaltra Mountains, Gascoigne Diver District, Western Australia^ 
and amongst them, reposing on a small Crinoid stem, is a pretty little 
Spirorhis, after the type of S. ambiguus, Pleming,^ from which I am unable 
to distinguish it. 
It has always been a matter of surprise to me considering the great 
thickness of brackish or fresh-ivatcr strata connected with our Palaeozoic 
Coal Measures, that examples of a Spirorhis, representing the adlierent 
S. carhonariiis, Murchison, of tlie European beds of more or less similar age 
have never been discovered.
