Vol. XXviii.] PALEONTOLOGY OF LANCASHIKE COAL MEASURES. 397 



Specimens from Carre Keys and Trawden, near Colne, 

 are in the Wild Collection of the Manchester Museum. 



Examples from the Lower Coal Measures of Water- 

 sheddings, near Oldham, are in the Geo. Scott collection of 

 the Museum of the Bacup Natural History Society. 



It is recorded from Halifax by Messrs. Crick and Foord 

 in association with D. discrepans and D. Looneyi. The 

 latter ought therefore to be looked for over the Mountain 

 Four Feet and Bullion seams in Lancashire localities. 



Gastrioceras (Goniatites) carbonariiim. 



This species has unfortunately been long confused with 

 the more familiar G. listeri, and often recorded as the latter. 

 They are often found in association over the Mountain Four 

 Feet and Bullion Seams, but G. carbonarium is the rarer of 

 the two, and appears to be restricted to the horizon men- 

 tioned, whilst G. listeri ranges downwards to the bottom of 

 the Coal Measures. 



The distribution is general throughout the Burnley, E,os- 

 sendale, and Oldham districts. A specimen from Burnley 

 Moor (C68082) is in the British Museum collections, as also 

 a second specimen (C2273) from Lancashire, with no locality. 



Gastrioceras (Goniatites) Listeri. 



We have already stated that this species occurs as a common 

 fossil over a wide area. Almost all collections of Lancashire 

 Coal Measure fossils contain several specimens of the species, 

 chiefly obtained from the horizon mentioned. 



It is recorded by Salter from the roof of the Gannister 

 Coal at — 



Shore Edge, four miles N. of Oldham. 

 Ogden Mill, five miles N. of Oldham. 

 Eoebuck Low, one and a half miles N.E. of Oldham.
