Vol. 67.] FROM THE NEIGHBOURHOOD OF UXEIER. 413 



These are underlain by the Prolecanites-comprtssus Beds of the 

 Cyaihaecoma Zone, with which Dr. Hind correlates the Codden -Hill 

 cherts. The report goes on to say : — 



'These beds [Codden-IIill cherts] are succeeded by black shale= and lime- 

 stones with Tosidononiya becheri and some compressed goniatites. (ilijphioceras 

 reticulotum has been obtained by Mr. Inkermann Rogers, and Mr. Hamling 

 notes the presence of (il. spirals at Filleigh. The latter species is very plenti- 

 ful in South Devon, at Waddon Barton. Most of the other fossils have been 

 found in the south part of the Culm area. 



'At Instow occur beds characterized by Gaxfrioccra* listeri, which are 

 succeeded by a series containing typical Coal-Measure plants and Carbonicola 

 acuta? 



It concludes with the statement : — 



' So in the difficult, much-disturbed county of Devon, all the life-zones of 

 the Pendleside Series known in the Midlands, with the exception of Glypkio- 

 ceras bUingue, have been found.' 



The last sentence is not quite clear, because, according to 

 Dr. Hind & Mr. Howe, the ' Pendleside Series ' occurs between the 

 Carboniferous Limestone Series and the Millstone Grit, and in 

 the list of zones above cited the ' zone of Gh/jp7iioceras biHns/ue' is 

 referred to the Millstone Grit. 



Again, in the second paragraph above quoted, after referring to 

 the plentiful occurrence of Gl. spirale at Waddon Barton in South 

 Devon, the report states : ' Most of the other fossils have been 

 found in the south part of the Culm area.' It is not clear to 

 which fossils allusion is here made, and reference to the literature 

 containing such records is not given. 



The fossils, however, described in the present note, support for 

 South Devon what Dr. Hind has stated to be the case in North 

 Devon, namely, that the Lower Culm-Measures are the homotaxial 

 equivalents of the ' Pendleside Series ' of the Midlands. 1

Discussion. 



Dr. T. F. Sjbly noticed that while the plant-remains collected 

 in this area were referred by Mr. Newell Arber to the Upper 

 Carboniferous, the molluscan fauna definitely indicated, on the 

 other hand, a Lower Carboniferous horizon, namely, the Pendleside 

 Series, underlying the level of the ' plant-break ' in the Midland 

 succession. He asked the Author whether the mollusca and the 

 plants had been found in different localities. 



Mr. Dewey remarked that, at Codden Hill and elsewhere in North 

 Devon, Prolecanites compressus occurred in beds of radiolarian chert, 

 which were overlain at Venn and Swimbridge by shales and lime- 



1 It may be mentioned that quite recently the ' Pendleside Series ' has been 

 discussed by Dr. Balduin Nebe in his work on the Culm fauna of Hagen in 

 Westphalia (Neues Jahrb. Beilage-Bd. xxxi, pt. 2, 1911. pp. 487 et seqq.).
