Dr. Wheelton Hind — British Carboniferous Goniatites. 435 



Tip to the Middle Coal -measures. This I showed to he the case in 

 my Presidential address to the Yorkshire Naturalists' "Union, and 

 published in the JVaturalisi, April to July, 1909, and elsewhere. 

 Many details have, however, been added since then, and an elahorated 

 and emended table will be published in a forthcoming paper by 

 myself and Dr. Wilmore, F.G.S., on the Carboniferous succession of 

 some Midland areas. 



The zones published in the Yorkshire Naturalist, op. supra cit., 

 p. 154, were as follows : — 



Millstone Geits . . Gastrioceras Ksteri. 

 Pendleside Seeies . . Glyphioceras bilingue. 



Q. spirale. 



G. reticiilatum. 



Posidonomya becheri. 



Cyathaxonia. 

 Caebonifeeous Limestone. Upper Dibunophyllum. 



It may be briefly stated that the Goniatites mentioned above 

 occur with the utmost regularity wherever these horizons are 

 exposed. Of the zones in the above list the G. reticulatum zone is 

 the least satisfactory, on account of the persistence of the species from 

 Pendleside to Middle Coal-measure times. Several other Goniatite 

 zones will be indicated in the forthcoming paper, with greater detail 

 as to their extent. Many of the localities given in the Museum 

 Catalogue (op. supra cit.) are unsatisfactory, parti}' because, at the 

 time when it was published, the zones of the Cai'bouiferous rocks 

 had not been made out, and partly because the real history of many 

 of the specimens in the Natural History Museum was not known. 

 Collections were largely referred to the town where the collectors 

 lived, e.g. Halifax, Todmorden. Halifax is given as a locality for 

 a large number of species which could not have come from the 

 Lower Coal-measures. I suspect that many of these, if not all, 

 came from the collection of the late J. W. Davis, of Halifax. I see 

 this fact was mentioned by Mr. Crick, Q.J.G.S., vol. Ixvii, pp. 400-4. 

 Long lists of fossils are given by J. W. Davis in his portion of the 

 volume, West Yorkshire, part i, Geology, 1878 (Davis and Lees), 

 but none are referred to Halifax as a locality. The " Hardbed Coal " 

 occurs there with tlie marine fossils of the Mountain Mine or 

 Bullion Coal, and the locality is correct for Gastrioceras Usteri, 

 G. carbonaritan, Bimorphocerasgilhertsoni, D. looneyi, andZ*. discrepans. 

 Tlie locality Halifax must therefore be called in question for all 

 Goniatites other than the above. Todmorden is also unsatisfactory, 

 for, though the Goniatite beds occur at that town, the majority of 

 the collections havebeen made from Horsebridge Clough, Crimsworth 

 Dean, and High Green Wood, north of Hebden Eridge, from the 

 valley of Hebden Water and its tributary. The two former localities 

 are in the same little valley. 



The Natural History Museum is fortunate in possessing nearly all 

 the types of Phillips's Goniatites, but the localities given bj' him are 

 practically valueless. Bolland is a large district, partly in Lanca- 

 shire, partly in Yorkshire, and practically the whole of the Lower 

 Carboniferous rocks occur therein. Black Hall, near Chipping, and
