new Species of Pleurotomide. 305 
_ Pleurotoma (Glyphostoma ?) exquisita. 
Pleurotoma vittata, Reeve (non Hinds), Conch. Icon. sp. 53, pl. vii. fig. 53. 
Hab. Island of Luzon, Philippine Islands. 
Pleurotoma (Glyphostoma ?) rubrocincta. 
Testa breviter fusiformis, turrita, rubescenti-alba, ad suturas rubro 
tincta et circa medium anfract. ultimi zona angusta rubra cincta ; 
anfract. 7, primus levis, secundus tenuiter crebre costatus, ceeteri 
superne decliviter tabulati, deinde angulati, infra angulum plani, 
ad suturam constricti, costis subconfertis (in anfr. ultimo 12-13 
fere ad basim continuis) instructi, liris spiralibus ad 6 supra cos- 
tas leviter incrassatis (in anfr. ultimo circiter 18, quarum due 
supra angulum ceteris minores sunt) cancellati; apertura an- 
gusta, longit. totius 4 paulo superans; columella obsolete den- 
tata; labrum extra incrassatum, intus ad 8-dentatum; sinus vix 
apparens; canalis perangustus, brevis. 
Long. 62 mill., diam. 24. 
Hab. Ovalau, Fiji Islands, 12 fms. 
The nearest ally to this species is P. fasciata, Gray. 
Pleurotoma (Glyphostoma ?) bathyraphe. 
Testa ovato-fusiformis, roseo-alba; anfract. 7, primus levis, secun- 
dus tenuiter arcuate costatus, ceteri leviter convexi, costis longi- 
tudinalibus 14 (in anfr. ultimo basi continuis) et liris validis 3 
(in anfr. ultimo 15) supra costas nodosis cancellati, sutura pro- 
funda canaliculata sejuncti; apertura angusta, longit. totius 4 
paulo superans; labrum extra incrassatum, intus dentibus 7 
(superioribus maximis) munitum, superne vix sinuatum; colu- 
tmella callosa, liris transversis circiter 6 ornata; canalis angustus, 
brevis. 
Long. 6 mill., diam. 24. 
a San Nicolas, Zebu, Philippines, 10 fathoms (Cu- 
ming). 
The cancellation of this species is very pretty, since the 
spiral lirations are thickened on crossing the ribs, and thus 
form transversely elongated tubercles. The suture is well 
marked and deep. 
Pleurotoma ( ?) sexcostata. 
Testa angusta, fusiformis, fusca ; anfractus 9, primi duo leeves, con- 
vexi, sequens 1-14 crebre tenuiter costatus, ceteri fere plani, 
costis 6 leviter obliquis, prominentibus (supra spiram continuis, 
et in anfr. ultimo vix ad basim continuis) instructi, liris spirali- 
bus 3 supra costas valde prominentibus, in interstitiis fere obso- 
letis, cincti; anfr. ultimus liris 13 ornatus, quarum tres infra
