Hind: Life Zones in British Carboniferous Rocks. gI 
G. listeri in the lower portion of the Coal Measures, does not 
seem to come in till late on in Millstone Grit times. 
Some years ago a collection was made from the Shales of 
Eccup, presumably underlying the 3rd Grit, on behalf of the 
Carboniferous Zone Committee of the British Association, before 
I became Secretary to the Committee. I, however, worked over 
a good deal of the material, and the list fairly represents the 
fauna :— 
Lamellibranchiata. | Cephalopoda. 
Aviculopecten gentilis. Celonautilus subsulcatus. 
Pterinopecten papyraceus. Glyphioceras reticulatun.. 
Postdoniella levis. Orthoceras morristanum. 
FA kirkmant. 
Nucula equalis. Brachiopoda. 
Nuculana stilla. 
Ctenodonta levtrostris. 
Schizodus antiquus. 
A large sulcate Kdmondia. 
Myalina peralata. 
Productus, a scabriculate form. 
Lingula mytiloides. 
Orbiculotdea nitida. 
The late James Spencer, of Halifax, watched the excavations 
and shafts sunk for the Halifax waterworks under Wadsworth 
Moor. 
He describes (Trans. Manchester Geol. Soc., Vol. XIII., 
pp. 209-212) the sections, and I make out the following species 
in his collection from that horizon, which he determines as the 
shales between the 3rd and Kinderscout Grits. 
Glyphioceras reticulatuim. Celonautilus quadratus. 
He phillipsit. Orthoceras aciculare. 
, bilingue. Posidoniella levis. 
Dimorphoceras gilbertsoni. 9 minor. 
a loonyi. | Pterinopecten papyraceus. 
Temnocheilus sp. Ptychomphalus ip. 
Solenochetlus cyclostomus. Productus sp. 
_ Spencer states that Gastrioceras listert and Nomismoceras 
sptrorbis occur here, but I cannot find specimens in his collection. 
Barnes and Holroyd have described a fossiliferous grit on the 
flanks of Pule Hill, near Marsden, which occurs in Netherley 
Quarry on Pule side. I visited the quarry on one occasion with 
them. They consider the bed to be either high up in the 
Kinderscout Grit or low down in the 3rd grit. The list of fossils 
contains no species typical of the horzion. Cephalopoda and 
Brachiopoda are conspicuously absent. Gasteropoda in the form 
of casts are referred by them to eleven species, of which the 
1907 March 1.
