APPENDIX 
Notes on the foregoing Table, with Descriptioyis of the 
New species. 
It is highl}' 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. 
Cylichna ovuvi-lacerti^ n. sp. 
Shell small, C3flindrical-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. 
Scalaria Leroy i,'^ n. sp. 
Shell turreted, cylindric, many-whorled, longitudinal ribs 
few, indistinct, base spirally striate, aperture oval. 
The example figured is a small one, but like nearlj' 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 m3' friend Mr. Louis Alex- 
an 4 er Le R03', to whom I am under great obligations for 
his kindne.ss in procuring me specimens of the Savanetta 
fossils, and without whose assistance my knowledge of the

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