crossed with longitudinal laminately scabrous strie ; 
aperture circular, lip broadly imbricately frilled.

Choanopoma fimbriatulum, Pfeiffer. 
Annularia finbriata, Schumacher. 
Hab. Jamaica. 
Remarkable for its extremely delicate fluted sculpture, 
densely scabrous throughout with overcrossing strie.

Cyctostoma Buanptanum. Cyel. testd angusté wmbili- 
catd, oblongo-turbinatd, subpellucido-alba, rufo-fusco 
subremote interrupte fasciatd, anfractibus rotundatis, 
lineis elevatis spiralibus, striis scabrosis densé decus- 
satis easculptis ; aperturaé parviusculd, labro late fim- 
briato, fimbrid subimbricata. 
Buianp’s Cyctostoma. Shell narrowly wmbilicated, ob- 
long-turbinated, subpellucid-white, rather distantly 
interruptedly banded with red-brown, whorls rounded, 
sculptured with spiral raised lines densely crossed by 
scabrous strie; aperture rather small, lip broadly 
frilled, frill slightly imbricated. 
Apams, Contr. to Conch. No. 1. p. 3. 
Choanopoma lima, vax., Pfeiffer. 
Hab. Jamaica. 
This appears to me to be distinct from C. lima. It is 
a more delicate shell, neatly encircled with rather distant 
interrupted linear red bands, and the frill is hghtly puck- 
ered. 
Species 135. (Mus. Cuming.) 
CycLostoMa LINcCINA. Cycl. tesld angusté umbilicata, 
subabbreviato-turbinatd, violaced vel carneo-alba, an- 
Jractibus rotundatis, lineis spiralibus elevatis, striis 
spinoso-scabrosis densé decussatis exsculptis ; apertura 
circulari, parva, late plano-fimbriato, fimbrid ad mar- 
ginem spinosa. 
Tue corpED CycLostoma. Shell narrowly umbilicated, 
rather shortly turbinated, violaceous or flesh-white, 
whorls rounded, sculptured with spiral raised lines, 
densely crossed by spinously scabrous striz; aper- 
ture circular, small, broadly flatly frilled, frill spmous 
the edge. 
Turbo lincina, Linneus, Syst. Nat. 10th edit. p. 765. 
Nerita lincina, Miiller. 
Cyclostoma lincina, Deshayes. 
Choanopoma lincina, Pfeiffer. 
Hab. Jamaica. 
The scabrous strize of this species are rather spinous at 
the point of crossing. 
Species 136. (Mus. Cuming.) 
CycLosToMA SCABRICULUM. Cycl. testd subcompressé 
umbilicatd, abbreviato-turbinata, fulvido-albda, anfrac- 
tibus rotundatis, lineis spiralibus elevatis, striis sca- 
brosis dense decussatis easculptis, ultimo dilatato-pro- 
ducto; apertura circulari, pared, labro late imbricato- 
Jimbriato. 
Tue scaBrous CycLostoma. Shell rather compressly 
unbilicated, shortly turbinated, fulvous-white, whorls 
rounded, sculptured with spiral raised lines, densely 
crossed by scabrous striz, last whorl dilately pro- 
duced; aperture circular, small, lip broadly imbri- 
cately frilled. 
Sowersy, Thes. Conch. p. 133. pl. 28. f. 147. 
Cyclostoma amabile, Adams. 
Choanopoma scabriculum, Pfeiffer. 
Hab. Jamaica. 
There is scarcely any variation between the sculpture of 
this and the preceding species, but the form is different, 
the last whorl being dilately produced.
