Glyphioceras (Goniatites) sp. near truncaium. 



An undescribed species, supposed to be closely allied to 

 G. truncatus, is recorded by Salter from Roebuck Low, 1 J 

 miles JN'.E. of Oldham, from over the Gannister Mine. 

 (Salter, Geol. Surv. Mem., Geology of the Country around 

 Oldham, p. 62.) 



Glyphiocerm (Goniatites) reticulatum. 



Recorded by Hull as Goniatites Gibsoni, from above Lower 

 Lomax, Bury, opposite Broad Oak Mill, from above the 

 Gannister coal. (Hull, Geol. Surv. Mem., Geology of the 

 Country around Bolton-le-Moors, p. 35.) 



Glyphioceeas (Goniatites) diadema. 

 This species is recorded hy Messrs. Crick and Foord from 

 the Coal Measures of Rochdale. From the description of 

 the specimens (C5908, Brit. Mus.) there is little doubt that 

 the horizon is that of the Bullion or Upper Foot Seam. 



Glyphioceras {?) (Goniatites) paucilohum. 



This species is only recorded by Messrs. Crick and Foord 

 from the Carboniferous Limestone of Yorkshire. 



It is mentioned by Salter as also occurring at Sholver, two 

 miles north-east of Oldham, over the Bullion coal. (Salter. 

 Geol. Surv. Mem., Geology of the Country around Oldham, 

 p. 62.) 



Dimorphoceras {Goniatites) Gilhertsoni. 



This species is generally known to collectors as "Goniatites 

 atratus,'^ and occasionally is found by hundreds in a single 

 "bawm-pot." It can be found in all sizes from a pin's head 

 up to others having a diameter of 15m.m. Larger specimens 

 are rare. It occurs abundantly in the "bawm-pots*' over 

 the Mountain Four Feet seam in the Burnley district, and 

 less frequently over the Bullion coal.
