Nucula tenuistrata. Obliquely oval, finely striated concentrically 5 

 beaks close to the anterior extremity. Length 4 lines, width 5 lines. 

 Specimens very imperfect, along with Cucullaia virgata 

 Loc. Between Huhbye and Joorun. 



Nucula ? cuneiformis. Transversely elongate-elliptical, gibbose, 

 smooth; beaks close to the anterior extremity, small, incurved. Length 

 6 lines, width 10 lines. 



Loc. near Charee. 



Pecten partitm. Broad, short-elliptical, depressed, marked with two 

 concave radii, which divide the surface into three parts, both externally 

 and internally, the lateral parts being flattened ; concentrically and 

 minutely waved, waves alternately larger and smaller ; ears small, near- 

 ly equal. Length 6 lines, width 5 lines. 



Loc. Hubbye Hills. 



Plicatulapectinoides^ {M. C t. 409.). If this differ at all from the 

 British species, it is in having rather more the habit of an Ostrea, which 

 is apparent in the e^jpansion of the edge. 



Loc. near Charee. 



Exogyra cornea, (M. C. t. 26 and 605.). The few specimens most de- 

 tached from the matrix appear not to be quite so deep as those figured 

 in the Mineral Conchology. 



Loc. Katrore Hills. 



Ostrm carinata (Lam. Hist. Nat. VL 216. M. C. 365=) ? The speci- 

 mens being generally much concealed in the stone or broken, the de- 

 termination of the species is not possible ; the most perfect individuals 

 resemble the young state of O. carinata, but that species is so near in 

 some slates to O. gregaria, (M. C. t. 111.) and O. solitaria ( M. C. t. 

 468 ), that fragments cannot be distinguished. 



Loc. near Charee. 



Ostrea Marshiz, (M. C. t. 48 ). The 0. Marshii varies so much in 

 different localities, that we find no difficulty in referring this shell to that 

 species, although the plaits are more numerous than usual. 



This specimen is accompanied with an imperfect Plicatula. 



Loc. Katrore Hill. 



Terehratula intermedia, (M. C. t. 15. f. 8.) var. A small specimen, and 

 rather more deeply plaited than most of the European varieties of the 

 species. 



Loc. near Charee, 



Terehratula hiplicata, (M. C. t. 90 and 437, f 2, 3.) var. A variety of this 

 variable species found in the red chalk at Hunstanton, is precisely simi«
