(5 6) Fauna of the Posidonomya-Beds IS'orth of Lough- 

 shinny Harbour (L16 to L30). 



(i) Corals: 



Zaphrcniis aff. Enniskilleni, Ed. & H. 



Amplexi-Zcq)h7'entis. 



Fseudamplexus. 



Cyathaxonia rushiana, Vaughan. 



Lonsdaloid Carcinophylhom. 



Cladochonus. 



Michelinia tenuisepta, var. favositoidcs 



nov. 

 Zaphrentis Omaliusi, var. ambigua, 



Carruthers. 

 Zaphrentid which occurs in the Mill- 

 stone Grit of Scotland {fide E. G. 



Carruthers) (cf. Z. Omaliusi, var. 



densa, Carr., and of. Densiphylloid 



Zaphrentis, sp. nov., of the JJibuno- 



phyllum-Lime&tone). ' 



(ii) Brachiopods : 



Froductus aniiquatus. Sow. ! Schizophoria resupinata (Mart.) 



Members of the series Froductus I (spinous var.). 



concinno-longispimcs (including Fr. \ Spirifer his^ilcatus, Sow. (variety ex-

(L 17 c) Komisrnoceras rotiforme (Phill.). 



(v) Plants: 



Lepidodendron Bhodeanum, Sternberg, and longitudinally-striate plant- 

 stems. 



Fosidonomya is not uncommon, and links the beds with P ; the 

 Michelinoid Favosites and Lonsdaloid Carcinovliyllum suggest a 

 low level in that zone, as does Nomismoceras rotiforme. The per- 

 sistence of Cyathaxonia rushiana into P is clearly demonstrated ; 

 the form is, however, distinct. 



(5 c) Repetition of the Fosidonomya-'^ediS, at Lough- 

 shinny Harbour (LIO to L13).
