266 A. J. Juke8-Broume — 



most of the so-called Warminster fossils have come, and the list 

 which follows is believed to be a complete catalogue of the fauna of 

 this Eye Hill Sand. 



From it have been excluded all phosphatized fossils and all 

 specimens which could be recognized by the matrix as having come 

 from the chert beds below, or from the still lower beds of green 

 sand, yellow sand, and buff micaceous sandstone which occur near 

 Warminster, Westbury, and Devizes. There are, however, still 

 some specimens about the exact gisement of which I feel doubtful, 

 and it is possible that a few species have been admitted into this 

 list which have not really come from the particular bed of Green- 

 sand in question. If, therefore, it is not a perfectly accurate list, it 

 will err rather in comprehending too many than too few. 



I have done all in my power, however, to make it as accurate as 

 possible, and have to thank many friends and correspondents for 

 assisting me in the matter. Messrs. G. Sharman and E. T. Newton 

 have kindly looked at all the fossils labelled " Warminster Green- 

 sand " in the cases of the Museum in Jermyn Street, with the result 

 that many were found to be phosphatic casts, and have consequently 

 been excluded from the present list. 



For the list of species entered under the second column (British 

 Museum) I am indebted to Dr. W. F. Hume, F.GS., who made 

 a careful examination of the specimens in order to distinguish the 

 true Warminster fossils from such as seemed to have come from 

 other horizons. 



The fossils in the Devizes Museum were examined and named by 

 myself in 1888, to the best of my ability at that time. The list 

 of those in the Woodwardian Museum, Cambridge, was made by 

 Mr. H. Woods, F.G.S., but some specimens about which doubt existed 

 were, with the permission of Prof. Hughes, sent to me for examina- 

 tion. In the same way I have to thank the Eev. H. H. Winwood 

 for allowing me to see most of those in the collection at Bath. 



The list of Polyzoais taken from the " Catalogue of the Cretaceous 

 Fossils in the Museum of Practical Geology" (1878) ; there is also 

 a collection of them in the British Museum, but they are being 

 revised by Dr. J. W. Gregory, who informs me that the nomencla- 

 ture of the Polyzoa (both genera and species) is in a very unsettled 

 state. 



The nomenclature of the Lamellibranchiate Mollusca is also 

 greatly in need of revision. The species of Pecten and Lima men- 

 tioned in the following list are especially open to correction : thus, 

 the names elongatus (Lam.), and Raulinianus (D'Orb.), are attached 

 to certain Pectens in most of the museums, but I doubt if they are 

 correctly so named. Again, the Pecten I have called P. GaUiennei 

 (D'Orb.), has usually been named P. interstriatus (Leym.), although 

 D'Orbigny pointed out in his Prodrome that Leymerie's name was 

 given to another Pecten by Munster in 1841. Moreover, the species 

 occurring at Warminster agrees more closely with that named 

 GaUiennei by D'Orbigny, than with the Aptian form which he 

 renamed Aptiensis.
