_ Description of some New Species of Fossil Shells. 95 
4 FAMILY SCALARIANA. 
Genus Scatarta.—Lamarck. 
S. elegans. % 1, fig. 6. 
S. testa turrita, imperforata, tenui, politd; spira acuta; anfrac- 
tibus senis, convexis, sessilibus; costis longitudinalibus quinde- e 
cim; suturis profundis ; columella levi; apertura elliptica. 
Shell turrited, imperforate, thin, polished ; spire acute ; whorls 
six, convex, sessile; with fifteen longitudinal ribs; sutures deep; 
columella smooth ; mouth elliptical. 
Length ‘1. Breadth ,';th of an inch. 
Remarks.—This is cnn of the most minute, and atthe same* .. 
time most elegant of the Scalari@ which I have seen. The last ~ x 
whorl is ribbed only to the middle. It differs from S. planulata, ~~ 
Lea, in having fifteen instead of twelve ribs on each whorl, in 
the mouth being elliptical, its size, &c. 
: S. venusta. Pl. 1, fig. 7. 
S. testa subulata, imperforata, crass; anfractibus , sessili- 
bus, convexis, costis tredecim ; ultimo nitGwicies carinato, costato 
ad carinam ; suturis profundis ; aperignt sub-elliptica, parva. 
Shell subslate, imperforate, thic , Sessile, con- 
) vex, with thirteen ribs ; last whorl eltintte, ribbed to the carina; 
sutures deep ; mouth sub-elliptical, small. 
| Length Breadth -25 of an inch. 
: Remarks.—tIn this species the ribs are quite thick, and there is 
| a large varix on each whorl. In this character it resembles the 3 
8. quinquefasciata, Lea, but it differs from it in other respects. I 
have been able to obtain but two specimens of this shell, both of 
which have the spire very much fractured ; enough however re- 
mains to convince me of its differing from any species that I have 
seen. 
J 
FAMILY TURBINACEA. 
Genus Turso.—Linneus. 
T. parvus. Pl. 1, fig. 8. 
T. test conica, ventricosa, umbilicata, crassissima, levi, polité ; 
umbilico parvo ; anfractibus quaternis, planulatis ; suturis impres- 
Sis; aperturA rotunda.
