New South Wales.

In order to test the existence of a ■wide-spread Devonian 
series in New South Wales, I requested (as stated elsewhere) 
my friend Professor De Koninek to undertake the examination 
of a collection of 1,000 Pakeozoic fossils, comprising the Upper, 
Middle, and Lower Pahcozic formations as they exist here, and 
in his account of the Devonian, received since the last edition of 
this memoir, he remarks in his “ Resume Gtologique ” (op. cit. 
p. 133), after giving the fullest assurance of all possible accuracy: 
“ Des quatrevingt-unc especes observes en y comprenant 
“ un spongiaire nouveau, mais non decrit a cause de V impos- 
“ sibilite cPen detincr le genre, ainsi qu’une tige de Rhodocrinvs ,

The author goes on to sav, that the first of this group of four 
appears in Australia to occupy the place which in certain beds 
in Europe, and very particularly in Belgium, is held by Reccp- 
tacnlitcs Ncptuni Defranee, which as the other belongs to the 
order of sponges. 
As the collections under review were made in part before 
1850, having been packed some years before they were sent for 
examination to my highly honored friend, much correspondence 
has taken place between us and as I have, since the specimens were 
received by him, made numerous explorations, and during these
