At an early date the larger collections made by the Ecv. AV. lb Clarke, M.A., 
P.E.S., commenced to he drawn upon, and in 184.7 we find McCoy^ describing 
from the Permo-Carboniferous of Harper’s Hill — Fecten suhquinqudineatus, 
and two Carboniferous forms Fecten ptycJiotis, McCoy, and Avicnla tesselatus, 
Pbill. 
In 1872, the late Mr. Robert Etheridge described' the large scries of 
fossils from Queensland brought together by iVlr. Richard Haintrce, and 
recorded the following Pectinidse : — 
Aviciilopccten (?) liimeformis, 3Iorris. 
,, imhricatus, Etheridge. 
,, multiradiatus, ,, 
In 1877, Prof. E. G. dc Koninck published the second part of bis 
classical work “ Recbercbcs sur Ics Eossils palcozoiques de la Nouvelle Galles 
du Sud”^ dealing with the large collections of Carboniferous and Permo- 
Carboniferous invertebrata collected by the Rev. W. B. Clarke. The 
following forms from the Permo-Carboniferous are dealt with : — 
Aviculopecten leniusculus, Eana. 
,, subquiuquelineata, McCoy. 
,, liimeformis, Morris. 
,, elongatiis, McCoy. 
,, profundus, Ee Ko)iinck. 
,, Eittoni, Moi-ris. 
,, illawarensis, Morris. 
In the same work lie referred a number of Carboniferous forms to European 
species : — 
Aviculopecten consiniilis, McCoy. 
,, depilis, McCoy. 
,, ptyebotis, McCoy. 
,, Knockonnieiisis, McCoy. 
,, cingendus, McCoy. 
,, grancsiis, Soicerhy. 
,, Eorbesi, McCoy. 
,, tesselatiis, Fhillips. 
As will be seen later on, we have been able to recognise only two of these forms.
