Hub. — Men}:?alum Is., north of Labuan. (Comm. H. Fulton.) 

 Eesembling in its general form J/, tuber culaia, IMiill., but may be 

 distinguished by its smooth and shiny epidermis and incised striae. 

 Its brilliant marking gives it a little the appearance of M. Uanleyi^ 

 Brot, or M. Dautzenbergi, Morlet. 



3. Melania. (Steiatella) exsebta, n.sp. Fig. 1. 



Testa subulato-turrita, solidula, Into atro obscurata ; spira Integra ; 

 anfr. circa 19 convexiusculi, sutura marginata divisi, longitudinaliter 

 erebre inciso-striati. Apertura ovata superne acuta ; margine dextro 

 simplici, baud sinuato ; columellari inerassato, parum arcuato, basali 

 vix etfuso, rotundato. Alt. 40, lat. 10 mm. ; apert. alt. 10, 

 lat. 6 mm. 



Hab. — Palawan. (Comm. H. Fulton.) 



It may be distinguished from all the other forms of the group 

 StriateUa by its extremely slender, concavo-subulate spire. The 

 young specimens show that under the black covering, the shell is 

 horn-coloured, marked with narrow brown flammules. 



4. Melania (Steiatella) pteamidella, n.sp. Fig. 2. 



Testa pyramidali-turrita, solidula, fnsco-cornea, punctis rubris infra 

 suturam et ad peripheriam notata. Spira Integra, anfr. 10, supremi 

 convexi, transverse costulati, sequentes convexiusculi, sub suturam 

 coarctati, longitudinaliter insequaliter inciso-striati, ultimus ad peri- 

 pheriam subangulatus. Apertura ovata, superue acuta, basi paulo 

 attenuata ; columella subrecte descendens ; margine dextro tenui, 

 acuto, vix sinuato. Operculum subspiratum, nucleo basali. Alt. 25, 

 lat. 9 mm. ; apert. alt. 9, lat. 5 mm. 



Hab. — Palawan. (Comm. H. Fulton.) 



Characterized by its pyramidal form and its last whorl being slightly 

 subangular but rounded at the periphery. A lighter zone runs below 

 the sutures. 



5. Melania (Steiatella) Palawanica, n.sp. Fig. 6. 



Testa tnrrita, solidula, cornea, sparsim rubro punctata. Spira 

 Integra; anfract. II vix convexiusculi, supremi nonnun(iuam infra 

 suturas plicati, omnes longitudinaliter inciso-striati, striis irregularibus 

 usque ad basin conspicuis. Sutura subnmrginata. Apertura ovato- 

 arcuata, superne acuta, basi paulo attenuata, anguste rotundata ; 

 columella parum arcuata ; margine dextro simplici acuto, baud 

 sinuato. Alt. 25, lat. 8 mm. ; apert. alt. 8, lat. 4 mm. 



Hab. — Palawan, Balabac. (Comm. H. Fulton.) 



This species has no shai-ply defined characters ; it resembles some 

 of the varieties of my M. Labuanensis that have flattened whorls. 

 I rather hesitate to describe it as new, but consider it is less injurious 

 to science to propose a needless species than to make a wrong identifi- 

 cation.
