﻿Vol. 6 1.] OF THE MARINE BANDS IN THE COAL-MEASURES. 537 



Ctenodonta hndtdlata (Phill.). (PI. XXXV, figs. 22 & 22 a.) 



In my monograph on the British Carboniferous Lamellibranchs 

 I have figured the cast of a shell from the roof of the Gin Mine, 

 Longton, as Nucula undulata. The genus should be more correctly 

 Ctenodonta, and it would have been more correct to have given the 

 horizon as below the Gin Mine. 



This species is much more tumid and cylindrical than Ctenodonta 

 losvirostris. Several other examples occurred in the Nettlebank 

 marine band, below the Gin Mine, on the same horizon as that in 

 which the shell was first found at Longton. 



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

 Coal. 



Solenomfa primj5va, Phillips. (PI. XXXV, fig. 24.) 



A single specimen was obtained by Mr. John Ward, many years 

 ago, from below the Gin-Mine Coal at Longton ; and I possess a 

 specimen from the Pennystone Ironstone of Coalbrookdale. 



Sohizodus antiques, Hind. (PI. XXXV, fig. 25.) 



This specimen was also obtained by Mr. John Ward from below 

 the Gin-Mine Coal at Longton. 



The species ranges from the upper part of the Pendleside Series 

 to the Coal-Measures. It also occurs above the Four-Feet Coal, 

 Wetley Moor (North-Staffordshire Coalfield), and in the roof of the 

 Bullion Mine, Carre Heys, Colne (Lancashire). 



Leiopteria longirostris, Hind. (PI. XXXV, fig. 26.) 



A single specimen, with the valves somewhat slipped on each 

 other, has been found in a marine band with Pterinopecten papyra- 

 ceus and Pt. carbonarius, 71 feet below the Four-Feet Coal in the 

 Cheadle Coalfield. 



The type-specimens of this species were obtained from one of the 

 black limestones at the base of the Pendleside Series, Mam Tor, near 

 Castleton. It is also found at Pendle Hill, Flasby Fell, and Horse- 

 bridge Clough, in beds of the same age. 



Mtalina compressa, Hind. (PL XXXV, fig. 27.) 



This species has now been obtained at several localities in the 

 North-Staffordshire Coalfield, some few feet below the Moss Coal, 

 in the Weston-Sprink marine band, and above the Seven-Feet 

 Banbury. It also occurs 71 feet below the Four-Feet Coal of the 

 Cheadle Coalfield, and at some horizons in South Staffordshire ; 

 also 80 feet below the Furnace Coal near Pilsley, in the Nottingham- 

 shire Coalfield. 



Scaldia minuta, Hind. (PI. XXXV, fig. 28.) 



I described under this title l a little shell, which occurs in large 

 numbers with other marine fossils. 



Locality. — Marine band at Weston Sprink, near Longton 

 (North-Staffordshire Coalfield).
