 The curled Eostellaria. Shell fusifonn, rather thick, 

 spire sharp, whorls rouniled, two-varicose, longitudi- 

 nally closely ribbed, interstices neatly cancellated 

 with nmnerous small ridges, columella straight, cal- 

 lous, lip very much thickened, cancellated, elegantly 

 curled at the upper part, apertm'e small ; glaucous 

 gi'cy, interior of the aperture chestnut, lip and cohi- 

 meUa whitish.

 f. 62, 63. 



Rostellaria crispata, Kiencr. 

 Hab. Philippine Islands ; Cuming, Belcher. 



This interesting little species, vei-y closely allied to 

 7^ cancUata in form and sculpture, is remarkably distin- 

 guished by the peculiar manner in which the sinuous pro- 

 duction of the lip is suddenly curled backwards. 



Species 9. (Mus. Cuming.) 



Rostellaria curta. Rod. testa fusiformi-turrUd, spird 

 valde acuminatd, canalt recto, anfractibus subplanatis, 

 paiich primis longitiidbiaUter costatis, cateris lavibus, 

 columelld callosd, labro qiiadri- vel qinnqiie-dentato, 

 mperm canalicidato-productu, cauali breviusculo, sub- 

 recurvo ; f/dvo-fuscescenfe, fascid latiiisctdd pallide 

 castaned infra suturas, columelld et apertura fance albis. 



The short Rostellaria. Shell fusiformly turreted, 

 spire very much acuminated, canal straight, whorls 

 rather flattened, the first few whorls longitudinally 

 ribbed, the rest smooth, columella callous, lip four- 

 to five-dentate, canaliculately produced at the upper 

 part, the canal being rather short and curved back- 

 wards ; light fulvous-brown, with a rather broad pale 



chestnut band beueatli the sutures, columella and 



interior of I lie aperture white.

Hab. ? 



The form of this shell is certainly distinct from any 

 variety that I remember to have seen of R. curvirostris, 

 from wliich it differs principally in the canal being straight. 

 It is impossible to characterize the length of the canal, as 

 it appears to have been filed at the extremity. The species 

 has not been coufinned by the discovery of a second spe- 

 cimen. 



Species 10. (Mus. Cuming.) 



Rostellaria cancellata. Eost. testa fusi/ormi, cras- 

 siuscidd, spird acidd, anfractibus subrotmidatis, bivari- 

 cosis, longiludiMaliter crebricostatis, interstitils Uris 

 parvis numerosis nitide cancellatis, columelld callosd, 

 leviter recund, labro incrassato, superne apicem versus 

 gracile canaliculato-producto ; glaucescente-fuscd, ma- 

 cutis parvis rubid'is fasciaiim tinctd, columeUd labroqne 

 albis, apertura fauce pallide castaned. 



TiiE cancellated Rostellaria. Shell fusiform, rather 

 thick, spu-e sharp, whorls somewhat rounded, bivari- 

 cose, longitudinally closely ribbed, interstices neatly 

 cancellated with numerous small ridges, columella 

 callous, slightly recurved, lip thickened, slenderly 

 canaliculately produced at the upper part towards 

 the apex ; light glaucous-brown, stained with bands 

 of smaU red spots, lip and columella white, interior 

 of the aperture light chestnut.

 edit.) vol. ix. p. 710. 

 Rostellaria cancellata, Kicner. 

 Strombus fissurella, Sowerby. 



Hab. Philippine Islands ; Cuming, Belcher. 



This species is more attenuated and compressed than 

 S. crispatus, and the channelled production of the Up, in- 

 stead of being suddenly cm-led backwards on the penulti- 

 mate whorl, is continued towards the apex over three or 

 four whorls.
