170 PROCEEDINGS OE THE SCIEOTIFIC ASSOCIATION. 
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. Le Boy, which is more like 
T. imbricata. 
Vej metus irilineaius 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 Yermetiform character. This shell was given 
as Vermetus Royanus in my list of Matura fossils published 
in 1864. It has not a deep suture as that species has. 
Triforis guttata n. sp. 
Beversed, cylindrical; whorls about 8, zoned with three 
Bpiral lines of small obtuse points which are connected spi- 
rally and longitudinally 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. Qentricosus 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.
