vi PREFACE. 
foreign localities, assigned to the species of Yorkshire Fossils in the 
Synoptic Table, are wholly gathered from these examinations, except 
a few instances quoted from the satisfactory authority of Brongniart, 
Goldfuss, and Voltz. — One of the most useful results of my inter- 
course with the latter of these eminent men, was the conviction that 
in respect of the species belonging to one important genus of Cepha- 
lopoda, (Belemnites) almost nothing was known in England, the re- 
searches of the late Mr. Miller being the only proof that any attention 
had been paid to the examination and classification of these curious 
fossils. I have lately examined with great care the whole series of 
belemnites in the Yorkshire Museum, in my own and some other 
cabinets, and the result as far as relates to the Yorkshire fossils is 
given in the Synoptic Table, and in the other Lists. 
A similar examination of a large series of specimens in the cabi- 
nets of Mr. Bean and Mr. Williamson, has made me acquainted with 
several new and curious Crustacea, which with other novelties in Fossil 
Botany and Zoology brought to light by the indefatigable collectors 
abovenamed and those who are zealously treading in their steps, will 
be figured in a Supplement, suited to both editions.
