FAUNA OF THE CLIFFWOOD CLAYS 331 



PELECYPODA 



1. Ostrea sp. undet. A small undetermined species. 



2. Amusium sp. undet. This is the same species noted in the fauna 

 of the crustacean nodules from the beach at Cliff wood. 



3. Breviarca sp. undet. This is the same species as that occurring 

 in the crustacean nodules at Cliffwood Point. 



4. Nuculana protexta (Gabb) ? 



5. Yoldia cf. evansi M. & H. 



6. Cardium sp. undet. This is the same species noted from the 

 sandstone slab collected at Cliffwood. 



7. Cymella bella Con. This species is represented by several 

 specimens. Elsewhere it occurs rarely in the Merchantville, 

 more commonly in the Woodbury, and most abundantly in the 

 Wenonah formation. 



8. Isocardia cliffwoodensis n. sp. 



9. Cyprimeria sp. undet. This is a small species which cannot be 

 identified with other New Jersey forms, but it is most like a 

 species in the Woodbury clay, where he genus occurs most 

 abundantly. A form apparently identical with this Cliffwood 

 shell occurs rarely in the Wenonah fauna. 



10. Tellina sp. undet. Several specimens of a shell apparently 

 referable to this genus are present in the fauna. They seem to 

 belong to an undescribed species. 



11. Linearia metastriata Con. This species rarely occurs in the 

 Merchantville clay, it is abundant in the Woodbury clay near 

 Haddonfie-d, and is one of the most abundant species of the 

 Wenonah sand. 



12. Veleda lintea (Con.). This is the most abundant species in the 

 fauna. 



13. Pholadomya occidentalis Mort. Several fragments which seem 

 to represent this species have been observed. 



14. Corbula sp. undet. A species of this genus, apparently unde- 

 scribed, is represented by several specimens. 



15. Leptosolen biplicata Con. This species has been recognized 

 elsewhere in the Merchantville clay, the Woodbury clay, and 

 the Wenonah sand, it being most common in the last of these 

 formations.
