I ’age ijo 
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. imbncata. 
Vermetus tn'litieatus 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 5'oung 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 Royanus in my list of Matura fossils publi.shed 
in 1864. It has not a deep suture as that species has. 
Trifoiis guttata n. S]i. 
Reversed, cylindrical ; whorls about 8, zoned with three 
spiral lines of small obtuse points which are connected spi- 
rall}' and longitudinall3' by threads ; suture impressed ; 
ba.se 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 
w’hich name it is given in my list of Matura fossils, 1864. 
Solatium semidecussatutu n. sp. 
Small, orbicular depressed, stronglj' decu.ssate on the upper 
surface, nearly smooth on the low'er surface ; umbilicus 
deep, its margins crenate and spirallj' striate. 
Pliocene, Matura. It is with .some doubt that I refer 
this species to the genus Solarium.
