The following is the original description of this species : 



"Testa ovato-trigona, crassiuscula, anfractibus senis, longitudinaliter 

 sulcatis, ultimo seriebus duabus ad tribus tuberculorum ornato, serie postica 

 eminentiore; apertura lata; margine interne labii externi dentato, dentibus 

 paucis distantibus; labio interno transverse costellifero; costellis anticis 

 prominentioribus. ' ' 



The Cuban specimens, which are doubtfully referred to this Domini- 

 can species, are preserved as casts only. They attained a size con- 

 siderably larger than was customary for C. sulcifera, but resemble it 

 in shape and general appearance, and are unlike any other described 

 species from this region with which I am acquainted. The largest 

 specimen at hand measures 9 cm. in length and 7.5 cm. in maximum 

 width. 



Locality. Calabazar, Province of Habana, Cuba, station 4291, 

 Wren. Sowerby's type was collected by Heneken in Santo Domingo 

 and the species has recently been obtained by Vaughan, Mansfield, and 

 Cooke from the base of the Chattahoochee formation at Red Bluff, 

 near Bainbridge, Georgia. 



Geologic horizon. Oligocene. 



Type. British Museum. 



Cassidea? species. 



Indeterminable casts of a medium-sized species with a high spire 

 were found at Crocus Bay, Anguilla. They attained an altitude of 

 about 5 cm. 



Locality. Crocus Bay, Anguilla, station 6966, Vaughan. 



Geologic horizon. Oligocene. 



Dolium species. 



An internal cast which resembles Malea camura, but appears to be a 

 little more cylindrical than that species. The impression of the inner 

 lip is obliterated, so that the specific characteristics can not be made 

 out. 



Alt., 36 mm.; diam., 26 mm. 



Locality. Crocus Bay, Anguilla, station 6894, Vaughan. 



Geologic horizon. Oligocene.
