﻿538 DR. WHEELT0N HIND ON THE PALAEONTOLOGY [Aug. IQ05, 



Cephalopoda. 



In the determination of the cephalopoda I owe thanks for 

 assistance to Dr. F. L. Kitchin, F.G.S., and Mr. G. C. Crick, F.G.S. 



Euphemus cf. E. TJrei. (PI. XXXVI, figs. 9 & 9 a.) 



Several specimens which I refer to this species occur in the 

 marine band below the Gin-Mine Coal at Nettlebank and Longton. 



Glyphioceeas eeticulatum (Phillips). (PL XXXV, fig. 29.) 



This species occurs at certain horizons in the Pendleside Series, 

 in practically every locality in the Midlands where these beds occur. 

 It is a shell which differs very much in outward appearance with 

 regard to its age. Its aperture has a peculiar shape. The edge 

 of the periphery is concave, making an acute angle with the margin, 

 on either side ; then a narrow lobe projects forward, below which 

 the lateral margin is concave. In the young, the shell is strongly 

 and coarsely ribbed ; but in the adult, the ribs give place to fine 

 sinuous striae reticulated by fine spiral lines. Glyphioceras bilingue 

 has a very similarly-shaped aperture. 



Glyphioceras reticulatum occurs below the Gin-Mine Coal, Nettle- 

 bank (North Staffordshire). 



Glyphioceeas Phillipsi (?) Foord & Crick. 1 (PI. XXXV, fig. 30.) 



This is a species which occurs in the Pendleside Series of High- 

 Green Wood, Hebden Bridge, Coldcoates, and at Foynes Island 

 (Co. Limerick). It has never been found in the Carboniferous Lime- 

 stone Series. 



Locality. — North-Staffordshire Coalfield: below the Gin-Mine 

 Coal at Nettlebank. 



Glyphioceras micronottjm (Phillips). (PI. XXXV, fig. 31.) 



This species is known from the Pendleside Series near Todmorden, 

 and some of the British-Museum specimens are labelled 'Halifax'; but 

 the exact horizon is not stated. This species does not seem to have 

 so restricted a range as Gl. Phillipsi, for it is stated that specimens 

 have been obtained from the Carboniferous Limestone Series of 

 Wetton. Phillips quoted Bolland as the locality for his type. 

 Unfortunately Bolland is the name of an extensive district, in 

 which the Pendleside Series and the Carboniferous Limestone are 

 both well developed. It may be pointed out that Wetton is 

 situated on Carboniferous Limestone, of the white and grey 

 varieties, containing a Visean fauna ; but the village is not far 

 from the black limestones of the Pendleside Series. The matrix 

 of the specimen from Wetton, which is No. C. 4399 in the National 

 Collection at the British Museum (Natural History), will decide 

 whether the specimen is from the Pendleside Series or no.
