2193 ft. 5in. below Ordnance datum) as a base-line, the lowest 
marine band, 8ft. 7in. thick, occurred 340ft. lin. above the 
Barnsley Coal, the section being 1 ft. 11in. of bastard cannel overlain 
by 6ft. 8in. of blackish bind with balls of pyrites, and contained the 
following fossils, mostly preserved in pyrites: Zingula miytiloides, 
? Posidoniella, Pterinopecten carbonarius, P. papyraceus, Scaldia 
carbonaria, Euphemus wurei, Macrocheilina sp., Glyphioceras sp., 
Celacanthus, ? Cheirodus, Megalichthys, Rhadinichthys  monensis, 
Fhizodopsis sauroides. Among these aecrochetlina was fairly 
abundant. 
The next bed occurred 564ft. lin. above the Barnsley Coal. 
The material was dark-blue bind with ironstone and small cank-balls, 
and the following forms were present : Lingula mytiloides, Orbiculotdea 
nitida, Myalina compressa, Straparollus sp., Huphemus urei, Naticopsis 
sp., Pleuronautilus costatus, Solenocheilus cyclostoma, Acanthodes, 
Cladodus, Cclacanthus, Megalichthys, Platysomus, Elonichthys or 
Acrolepis, Rhizodopsis. Among these Straparollus is new to the 
Middle Coal-measures. 
The next marine band, 20 ft. 0} in. thick, lies 708 ft. 102 in. above 
the Barnsley Coal, the section being 19 ft. 03 in. of dark greyish-blue 
shale with hard cank-balls, resting on 12 inches of argillaceous 
limestone. It contains an abundant fauna, including twenty-six 
genera and thirty-five species of invertebrates, all marine forms.

Pseudamusium anisotum has not hitherto been found above the 
Carboniferous Limestone. Among the fish-remains Listracanthus 
should be noted. 
The highest bed occurs 1000 feet below the summit of the Middle 
Coal-measures and 1244+ feet above the Barnsley Coal. It is 
10 ft. 11 in. thick, consisting of grey bind with ironstone bands, of 
greasy appearance. The fauna is poor, but Goniatites are not 
uncommon. Lingula mytiloides, Orbiculoidea nitida, Myalina com- 
pressa, Nuculana acuta, ? Bellerophon sp., Glyphioceras phillipsi, G. sp.,

Among the fish-remains Listracanthus is to be recorded. 
The writer is indebted to Dr. Wheelton Hind, F.G.S., and 
Dr. A. Smith Woodward, F.R.S., for examining and naming the 
fossils.
