154 DEVONIAN FAUNA. 



0. striatulum, 0. tubicinella, Goniatites carbonarius, G. vinctus, and two Clymenide; 

 of these, two were from the Culm, three from the Clymenia-beds, and two from 

 the Limestones. 



Of the forty-three species given in Phillips's ' Palgeozoic Fossils,' we have seen 

 that twenty-two (counting synonyms) are to be included in our present list. 

 Seventeen species come from South Petherwyn, viz. seven Clymenige, Goniatites 

 bifer, Phill,, G. linearis, Miinst., G. insignis, Phill., Nautilus megalosipho, Phill., 

 Gyrtoceras ? rusticum, Phill., 0. cinctum, Sow., Orthoceras laterale, Phill., 0. ibex, 

 Sow.,^ and 0. ludense. Sow. ; and of these only four occur at Lummaton or Wol- 

 borough. He also gives four from the Upper Devonian of North Devon, viz. 

 0. ? tentaculare, Phill., 0. lineolatum, Phill., 0. ludense. Sow., and 0. imbricatum, 

 Wahl., of which the last two are common to the Wolborough beds. Another 

 species, Cyrtoceras bdellalites, Phill., is from Mudstone Bay; and five more, Ortho- 

 ceras cylindraceum, Sow., Goniatites spiralis, Phillips, G. crenistria, Phill., G. 

 mixilobus, Phil]., and G. spirorbis, Phill., belong to the Culm. 



M'Coy, in the ' British Palaeozoic Fossils,' describes Aganides vinctus. Sow., 

 sp. {=z Goniatites insignis, Phill.), Cyrtoceras bdellalites, Phill., G. reticulatum, Phill., 

 C. subomatum, M'Coy, 0. striatum, Sow., Gycloceras striatulum, Sow., sp., C. 

 tubicinella, Sow., sp., and six Clymenige, of which two are new species. 



In 1877 Mr. Lee drew attention to the occurrence at Saltern Cove, near 

 Paignton, of the following Cephalopods belonging to the Upper Devonian Fauna of 

 Biidesheim : Goniatites auris, Quenst., G. retrorsus, Quenst., G. Ausavensis, Stein., 

 G. Gerolsteinus, Stein., G. primordiaUs, Quenst., G. Prumiensis, Stein., and Ortho- 

 ceras {=Bactrites) Schlotheimi, Quenst. This locality is of great interest, for, 

 while it distinctly contains an Upper Devonian Fauna, it is most difficult to 

 separate it stratigraphically from adjacent beds containing Pleurodictyum problem- 

 aticum and other Lower Devonian types. Most likely Barrande would have 

 regarded it as a " colony ;" but, in view of the extraordinary local variability in 

 thickness of the Middle Devonian Limestones, it seems possible to recognise in this 

 spot a point of rest during Middle Devonian times, where, consequently, the 

 Intumescens-stage was immediately superjacent on and undistinguishable from the 

 Lower Series. 



Another interesting locality, brought into prominent notice by Mr. Lee, is 



probably belongs to the species described above as O. Rohertsii, under the beading of which it should 

 be added as a synonym. 



^ It appears that D'Orbigny in his ' Prodrome,' p. 54, has separated the Orthoceras ibex of 

 Phillips from that of Sowerby without assigning a reason for doing so. Both names, O. ibex, Phill., 

 and 0. JPhillipsii, D'Orb., have been kept side by side in Etheridge's Catalogue ; but this is evidently 

 an oversight. It would seem, therefore, that D'Orbigny's name must supersede the name O. oryx 

 which I have proposed in the text, unless my specimen should prove different from Phillips'.-^, which 

 I do not at all expect will be the case.
