 distinct ; pale golden colour. 



Reeve, Pro. Zool. Soc, 1845. 



Hub. Island of Luzon, Philippines ; Cuming. 



A delicate shell of so bright a hyaline texture that the 

 pillar of the shell may be seen throughout. 



Species 213. (Mus. Cuming.) 



Pleueotoma saturata. Pleur. testa pyramida li-acumi- 

 natd, inferne subcontractd, anfractibus striis transversis 

 et longitudinalibus creberrime granoso-reticulatis ; ca- 

 nali breviuscido ; labro subtiliter crenulato, sinu dis- 

 tincto; intus extusque fused, fasciis albis longitudina- 

 Ubus subdistautibus, facia unicd transversa in anfractu 

 ultimo, oruatd. 



The deep-coloueed Pleurotoma. Shell pyramidally 

 acuminated, somewhat contracted at the lower part, 

 whorls closely granosely reticulated with raised striae ; 



canal rather short ; lip finely crenulated, sinus distinc 

 deep bright brown within and without, ornamenti 

 with rather distant longitudinal white bands, with 

 single transverse band on the last whorl. 



Reeve, Pro. Zool. Soc, 1845. 



Hab. Island of Corrigidor, Philippines (found among coar 

 sand at the depth of seven fathoms); Cuming. 



This interesting and very characteristic species is of 

 bright deep brown colour marked out into large irregul 

 scraares by whitish bands. 



Species 214. (Mus. Cuming.) 



Pleueotoma igniflua. Pleur. testa ovato-oblongd, tran 

 versitn creberrime elevato-striatd, longitudinaliter ec 

 tis latiusculis approximatis, apicem versus couspicu; 

 basin versus obsoletis ; canali brevi ; labro intus cren. 

 lato, sinu superficiario ; albidd, Jlammis fulvo-auranti 

 undato-jiuentibus omatd. 



The fiee-flowing Pleueotoma. Shell ovately oblon 

 transversely very closely elevately striated, longitud 

 nally ribbed, ribs rather broad, approximated, co: 

 spicuous towards the apex, obsolete towards the basi 

 canal short, crenulated within, sinus superficia 

 whitish, ornamented with waved-flowing fulvoi 

 orange flames. 



Reeve, Pro. Zool. Soc, 1845. 



Hab. ? 



A strongly marked species partaking almost as much 

 the characters of Triton as of Pleurotoma. 



Species 215. (Mus. Cuming.) 



Pleurotoma patula. Pleur. testa ovato-oblongd, infen 

 ventricosd, subobliqud, anfractibus teuuibus, transversi 

 subtilissime et creberrime striatis ; canali brecissim 

 truncato ; labro simplici, sinu profunda, aperturd an 

 pld ; albidd, Jlammis fulvo-aurantiis, undatis, longiti 

 dinaliter Jluentibus omatd. 



The open-mouth Pleueotoma. Shell ovately oblon] 

 ventricose towards the lower part, rather obliqu 

 whorls thin, transversely very finely and closely str 

 ated ; canal veiy short, truncated ; lip simple, sirfl 

 deep, aperture large ; whitish, ornamented with loi 

 gitudinally flowing waved fulvous orange flames. 



Reeve, Pro. Zool. Soc, 1845. 



Hab. Bolinao, Island of Luzon, Philippines (found und< 

 stones at low water) ; Cuming. 



The species in this plate all present very distinct an 

 characteristic variations of form and sculpture.
