 APPENDIX 



Notes on the foregoing Table, with Descriptions of the 

 New species. 



It is highl3 r probable that some of the names given in 

 the above list will prove, upon a close examination of the 

 fossils, to be synonyms — and doubtless others will be found 

 to be still existing, such as Cardium haitense of Sowerby, 

 which I dredged up in the Gulf of Paria. But there are 

 still a great number of undescribed and extinct species, 

 chiefly in the collection of the Geological Society, and many 

 othe.s will yet be discovered. 



Shell small, cylindrical-subovate, minutely striate trans- 

 versely ; spire small, sunken ; aperture as long as the shell, 

 dilated anteriorly ; outer lip straight, blunt ; columella callus 

 with a strong tortuous fold. 



Lower Miocene, Manzanilla. 



Shell turreted, cylindric, many-whorled, longitudinal ribs 

 few, indistinct, base spirally striate, aperture oval. 



The example figured is a small one, but like nearly all 

 the molluska of the Caroni series in Trinidad, the shell 

 appears to have grown to a very large size, for another 

 specimen in my cabinet is upwards of six inches long. I 

 have dedicated this species to my friend Mr. Louis Alex- 

 ander Le R03 7 , to whom I am under great obligations for 

 his kindness in procuring me specimens of the Savanetta 

 fossils, and without whose assistance my knowledge of the

 1874, pi. XVIII. G. D. H.]
