Choanopoma decussutuin, Pfeiffer. 
Hal. Porto Rico. 
There is no spiral sculpture in this species. The term 
“decussated ” appears to have been applied by Lamarck 
to express the dense crossing of the whorls by Icngitudinal 
ridges.

CYCLOSTOMA DECOLORATUM. Cycl. testd subampliter um- 
bilicatd, conico-turbinatda, solidd, albd, anfractibus ro-

THE DIscoLouRED CycLostoma. Shell rather largely 
umbilicated, conically turbinated, solid, white, whorls 
rounded, spirally linearly grooved, intermediate ridges 
densely scabrous, last whorl rather loose ; aperture 
circular, lip frilled, frill thickened, imbricated. 
GunpLacu, MS. in Mus. Cuming.

Of unusually solid growth, with the frill encircling the 
aperture quite thickened.

Cycl. tesld compresse umbili- 
tibus conveuis, longitudinaliter tenuissime filoso-striatis, 
suturis conspicue opaco-crenatis, anfractu ultimo laxe 
producto ; apertura pyriformi-ovatd, parva, labro ex- 
mie fimbriato-reflexo. 
Daupinot’s CycLostoma. Shell compressly umbili- 
cated, cylindrically acuminated, livid fulvous, whorls 
convex, longitudinally very finely thread-striated, su- 
tures conspicuously opakely crenated, last whorl 
loosely produced ; aperture pyriformly ovate, small, 
hip delicately fimbriately reflected.

Hab. Cuba. 
The sutural crenations of this species are opake and 
large compared with the livid semitransparency and fine 
longitudinal sculpture of the rest of the shell.

THE SCARLET-TINGED CycLos’oMa. Shell compressly 
umbilicated, cylindrically oblong, scarlet-tinged ful- 
vous, sparingly dotted with red-brown, whorls con- 
vex, spirally ridged, ridges linear, close-set, interstices 
very finely latticed, sutures spinosely crenulated ; 
aperture circular, lip broadly imbricately frilled, frill 
a little dilated on each side.

This and the two preceding species, collected in the is- 
land of Cuba by M. Gundlach, are three well-defined and 
interesting additions to the genus.
