Page 4 - ISOii), jin. 264-270, instance, that some are very imperfect, others are in the condition of more or less distorted casts and impressions, and in the great majority of cases only one valve is figured. It will be readily admitted that this condition is more than unsatisfactory and not conducive to accurate determination, and as a tentative solution we propose publishing a series of photographic reproductions of specimens illustrating our interpretation of the different species.
Page 3 - Collection, described by John Morris, is in the British Museum (Natural History) ; the first Clarke Collection, described by McCoy, is deposited in the Sedgwick Memorial Museum, Cambridge ; the Dana collection is in the United States National Museum, Washington ; and the even more important collections brought together by WB Clarke, and described by De Koninck, was totally destroyed by fire ; while the Daintree Collection of Queensland fossils is believed to be also lost.

Page 3 - Owing to this scries of calamities some points can never be definitely settled, and uncertainty of identity is augmented by the fact that many species were created on single, and others on imperfect, specimens — either fragmentary or in the form of casts. These disabilities are perhaps most marked in the case of the PermoCarboniferous Pelecypoda, and more especially in the case of the Aviculopectinidic.
Page 1 - Marine beds of New South Wales, and in fact of Eastern Australia, is the variety and large size of the Pectinoid shells, one very noticeable fact being the apparent isolation of types displayed by these genera.
Page 7 - I think, in the unfortunate circumstance of the absence of any definite indication, that it is a good and simple rule to regard the first described species as the type of the genus.
Page 8 - The original description is quite insufficient for the recognition of this species, and were it not for the figure, it would be necessary to relegate the name to the rejectamenta.
Page 7 - Pectinidai to the Pteriidce, and may possibly be distinct from them both, though it is evidently more closely allied to the former than the latter.
Page 7 - Aviculipecten, because they have a narrow linear hinge plate, and the posterior is not marked off from the rest of the valve, I have referred them to Pterinopectcn, Hall. Neither of these three species can in any way be regarded as the type of Aviculipfcten.
