Caroni Series, Savanetta. A very distinct species, re- 

 markable for its almost entire want of ornamentation, and 

 the flatness of its whorls. I have lately received another 

 species of Turritella from Mr. LeRoy, which is more like 

 T. imbricata. 



Vermetus trilineatus n. sp. 



Conic-cylindric, turreted, spire pointed, whorls flat, bear- 

 ing three narrow spiral keels ; lower whorls irregular : 

 suture distinct, linear shallow. 



Pliocene, Matura. The young shell is not to be distin- 

 guished from a small Turritella, but the subsequent growth 

 supplies the Vermetiform character. This shell was given 

 as Vermetus Roya?ias in my list of Matura fossils published 

 in 1864. It has not a deep suture as that species has. 



Tr if oris guttata n. sp. 



Reversed, cylindrical ; whorls about 8, zoned with three 

 spiral lines of small obtuse points which are connected spi- 

 rally and longitudinal^ by threads ; suture impressed ; 

 base with three or four strong striations ; aperture pro- 

 duced into a canal ; peristome produced, inner margin with 

 a narrow defined callus. 



Pliocene, Matura. Allied to T. ventricosus Gmel., under 

 which name it is given in my list of Matura fossils, 1864. 



Solarium semidecussatum n. sp. 



Small, orbicular depressed, strongly decussate on the upper 

 surface, nearly smooth on the lower surface ; umbilicus 

 deep, its margins crenate and spirally striate. 



Pliocene, Matura. It is with some doubt that I refer 

 this species to the genus Solarium.
