Vol. XXviii.] PALAEONTOLOGY OF LANCASHIRE COAL MEASUKES. 589 



Tellinomya n. sp. 

 Three specimens of what I believe to be an undescribed 

 species from the Cannel Mine of Watergate Colliery are in 

 the Manchester Museum. (L. 3332, M.M.) 



Nucula Icevirostrum {Portlock). 

 From over the Great Mine at Ashton-under-Lyne. (Dr. 

 Hind, Pal. Soc, Monog. Carbon. Lamell., p. 184.) 



Schizodus sp. 

 From Worsley, no horizon stated. (Salter, Geol. Surv. 

 Mem., Geology of Country around Bolton-le-Moors, p. 41.) 



Carbonicola (olim Anthracosia). 

 Carhonicola robusta (Sow). 



An interesting suite of specimens of this species are in the 

 Wild Collection of the Manchester Museum, having been 

 obtained from about six inches over the Five and a half- 

 inch coal in the Diamond shaft, Bardsley. The coal occurs 

 at 636 yards from the surface. The interest of the specimens 

 lie in the fact that they show varietal development, which 

 would seem to indicate that they merge on the one hand into 

 Carbonicola acuta, and on the other into the more typical 

 C. robusta, such as is found at Burnley. 



Typical forms of C. robusta are found in the roof shales 

 of the Lower Yard Bed, Fulledge Colliery, Burnley. (W. 

 511 and W. 512, e. coll. Wild, M.M.) 



From the Bastard Cannel at 16 yards in the Fulledge 

 Colliery, Burnley. (W. 515, e. coll. Wild, M.M.) 



From the " Mussel-bed " of the Pendleton Colliery. 

 Examples in the Manchester Museum. 



From the Middle Coal Measures of Hulton, near Bolton, 

 (e. coll. Tonge, M.M.) 



From the Arley Mine at Gidlow Colliery, Standish. (L. 

 1053, M.M.) Collected by Mr. Higson.
