Cyathophyllum Murchisoui, E. & H. 



JHlmnophyllum d-y\i, Vaughan. 



At the smaller quarry at Hendre we collected from the limestone, 

 corresponding to No. 1 of the preceding section : 



Lithostrotion basaltiforme (Phill.). 

 Froductus Cora, D'Orb. 



And from the overlying limestone and shale — 



THhimophyUum sp. P. ptinctatus (Mart.). 



Lithostrotion irregttlare (Phill.). P. semiriticula/us (Mart.). 



Crinoids. Rhipidvmella Afichelini (ij'Eveille). 



Athyris plaiiosulcata, Phill. Schizophoria resupinata (Mart.). (Common.) 



Camarotwchia pleurodon (Phill.). Seminnla ambigna (Sow.). 



Chonetes Lagutssiana, De Kon. Spirifer triiingnlaris (Mart.). 



Productus latissinius, J. Sow. Spiriferina crtsfata, Schloth. 



P. longispinus, Sow. (Common.) Al/orisnia-Yike shell. 



(xxii) The exposure at Gwernymyndd is an important one, and 

 although it differs somewhat in its lithological character from those 

 seen elsewhere, its paljeontological features can easily be identified 

 with those of other localities. 



The following is the sequence of the upper strata at this place:- 



6. Grit and sandstone. 



5. Eucrinital and arenaceous limestone. 



4. Shale, 



3. Chert band. 



2. Quartz-grit and sandstone. 



1. Eucrinital limestone. 



In the grit and sandstone at the top of the section, which was 

 largely disintegrated, we found many fossils — the number of fish- 

 teeth being extraordinary. The list ()i)tained was — 



Lithostrotion irregnlare (Phill.). Spirifcr sp. 



Lonsdaleia rugosa, M'Coy. Ctenoptychius lobatus (R. Eth., juu.). 



Crinoids. Cochliodont tooth. 



Orthotetcs crcnistria (Phill.). Potcilodus sp. 



Productus longispinus, Sow. 



The upper portion of the limestone (No. 5) below the grit was 

 * rubbly ' in character, and contained Productus gigantens in fair 

 abundance; in the lower portion we collected — 



Amplexi-zaphrentis, Vaughan MS. Chonetes Laguessiana, De Kon. 



I)tbiinopItylli(m sp. Martinia glabra (Mart.). 



Fistalipora all', incrustans, N. & T. Productus panctatus (Mart.). 



(Vaughan). P. pustulosus, Phill. 



Crinoids. SpiriJ'er bisulcatus, Sow. (Common.) 



Athyris planosulcata, Phill.
