W'estindian Miocene, O. haitensh and O. virginicc^ do not appear 

 in this collection. 



Cardium compressum Dale. 

 Flor. Foss. Pt. v, P. 1109, PI. xlviii, F. 21. 



A rca consobrina — Sower by. 

 Journ Geol. Soc. 1850, PI. x, F. 12.

Dall prefers the name of halido7iata (Flor. Foss. Part iii, 

 Page 646) and he rejects Gabb's identification with A floridana. 

 Like most arks the shell is variable but I am satisfied that our i 

 shell is the one intended by Sowerby in his Figure. Dali's figure 

 in my opinion does not represent Sowerby's co?isobrina^ which is 

 more like his actinophora in shape, though the proportions are 

 not exactly the same. 



Ranina cuspidata. — Guppv. 



This crustacean from the Tamana beds was described and 

 figured by me in the Bulletin cf the Agricultural Department, 

 1909. 



Balanns porcatus. — Darwin. 



Barnacles probably of this species are not uncommon in the 

 miocene deposits and there is a bed composed chiefly of them at 

 the Government Farm in Tobago. A few specimens are in the 

 collection from Springvale. 



Jh isus cxiguus. — Cotteau. 



Ecbinides leiliaires de S. Parts &c», p. 35, PI. vi , F. 16-18. 



The examples are large, but are only casts. The species 

 was recorded by me in 1866 fron Anguilla under the name cf 

 Jj. dimidiates from which it differs slightly.
