216 Revietus — Mesozoic Flora of Graliam Land. 



Measures below and the Halesowen Sandstone group above. The 

 locality from which Mr. Kay obtained the specimens, which he lias 

 kindly placed in mv hands for description, is the Granville Clav 

 Pit, at Old Hill. 



In the present note I propose to indicate briefly some of the 

 species represented, which I hope on a future occasion to describe 

 more fully. They are very well preserved, as a rule. 



The Equisetalean remains are not very numerous, and of these the 

 specimens of the external surface of Calamites ramosus, Art., are the 

 inost interesting. Annular ia sphenuphylloides (Zenker) and Calamo- 

 cladus eqimetijormis (Schl.) also occur. The Sphenophyllales are 

 represented by SphenophjUiim cuneifolium var. saxifragmfolium 

 (Sternb.). The fern-like plants include a Renaultia, probably 

 It. Footneri (Marrat), Neuropteris Jlexuosa, Brongn., and iV. tenuifolia 

 (Schl.). The Pecopterid types are varied, good specimens of 

 Pecopteris oreopteridia (Schl.), as well as P. Miltoni (Art.) and 

 P. {Dactylotheca) plumosa (Art.), occurring. A Khabdocarpua, which 

 may be compared with R. nulcatus (Presl), is also present. 



The Lycopods are represented by Sigillaria principis, Weiss, 

 Lepidophloios acerosus (L. & H.), and Lepidostrohus variabilis, L. & H. 

 The most interesting fossil, however, is what I take to be a small 

 specimen of tlie cone of Sigillariostrohus nobilis, Zeiller, which is the 

 lirst record of this interesting species from Britain. I have also, 

 curiously enough, obtained several undoubted examples of the same 

 ])lant from the Wyre Forest Coal-field recently, and these I hope to 

 describe before very long. 



The known flora of the Old Hill Marls is too small at present to 

 indicate the horizon of these beds beyond doubt. While many of the 

 above species are most abundant in the Middle Coal-measures, the 

 presence of Pecopteris oreopteridia (Schl.) and Neuropteris Jlexuosa, 

 Brongn., species which have not been recorded below the Transition 

 Series, indicate that the later is the probable horizon. The Old Hill 

 ' Marls probably occupy a low position in the Transition Coal-measures. 

 The known flora of this horizon in South' Staffordshire at present 

 consists of eight species, recorded by Dr. Kidston ' from the 

 Hamstead boring between 1,236 and 1,320 feet, and of these 

 only the composite Lepidostrohus variabilis, L. & H., is also found 

 in the Old Hill Marls.

 ri^HE evidence that the existence of genial climates at the Poles 

 X has been the rule rather than the exception in the past is one 

 of the most fascinating and noteworthy results of the study of fossil 

 plants. The present memoir, none the less welcome because it 

 appears in excellent English, is the most important contribution
