86 CONTRIBUTION TO THE PALEONTOLOGY OF TRINIDAD. 



Cassis togatus var. soldadensis new variety. Plate XII, Figure 7. 



Remarks. — Two shells were collected by Mr. Veatch from Bed No, 2, Sol- 

 dado Rock, which are very clpsely related to Cassis togatus White from the 

 Maria Farinha beds, Brazil. 



Dr. White's description and his figure 13 tally so well in the main with the 

 Soldado shell that the differences between these forms seem varietal only. 



Description. — The Soldado shells can be distinguished from those of Maria 

 Farinha by their sharper varices; also in well preserved specimens, by the 

 fine and beautiful cancellation of the entire surface of the body whorl due to 

 the intersection of close, sharp transverse striae with more delicate lines of growth. 



This cancellation is slightly indicated in White's figure 15, but it is much 

 sharper and more regular on the Soldado shell. 



When complete the shells from Soldado would not have measured more than 

 23 or 24 mm. in length, while those from Brazil reached nearly 30 mm. 



In general the Soldado variety was a somewhat smaller and more elegantly 

 formed and sculptured shell than the Brazilian type. This species has not been 

 found in the Eocene of our Southern States. 



Locality.— Bed No. 2, Soldado Rock, Gulf of Paria. 



Geological horizon. — Midway Eocene. Equivalent to the Midway of Alabama 

 and of the Rio Maria Farinha beds, State of Pernambuco, Brazil. 



Genus CYPILflSA Linnaeus, 1758. 

 Cypraea bartlettiana new species. Plate XI, Figures 11, 12, 13. 



Description.— Shell small, solid, broadly pyriform, very globose; surface un- 

 sculptured, wholly smooth except for fine, transverse lines of growth; spire en- 

 tirely enrolled and concealed, very slightly sunken; aperture rather narrow, 

 widening towards the base; inner lip with about twelve fine plications decreasing 

 in size from the base upwards, plications on the outer lip concealed by the indurated 

 matrix; columella pinched at the base into a very sharp ridge. 



Height 18, width 14, thickness 11 mm. 



Remarks.— This and the succeeding species are the only Cyprseas that have 

 ever been described 66 from the Midway Eocene. A single species C. smithii has 

 been described by Mr. Aldrich from the Lignitic of Alabama. 67 The latter shell 

 is of somewhat the same general type as C. bartlettiana, and has the same sharp 

 columellar ridge, but the form of the shell is flattened instead of globular. 



In 1887 Dr. White described a peculiar Cyprsea-like fossil from Rio Piabas, 

 State of Para, Brazil, as Cyprceactceon pennce, new genus and species. 68 This has 

 a very deeply sunken spire, and bears no resemblance to the Soldado shell 



Locality.— Bed No. 2, Soldado Rock, near the Serpent's Mouth, Gulf of Paria. 



66 Professor Harris (Bull. Am. Pal., vol. I, p. 217, 1896) mentions finding two Cypraas in the 

 Midway of the Gulf States, one smooth, the other reticulated, but neither was sufficiently well pre- 

 served to describe or figure.
