Testa perforata, conica, saturate oUvaceo-fusca, nite^is ; spira elata, 

 convene conoidea, ad apicem pallidior, obtusa ; anfractus 6, cou- 

 ve.vi, lente accrescentes, striis minutis piaucis spiralibus hie illic 

 sculpti, ultimus ad peripheriam rotundatus, infra medium 

 concentrice tenuissime striatus ; apertura parva, Imiata ; perist. 

 tenue, margine columellari leviter incrassato, pallida, rejiexo ;

 obtusa ; anfractus 6, convexi, lente accrescentes, sutura profunda 

 sejuncti, liris tenuissimis spiralibus 4-5 et lineis incrementi 

 obliquis arcuatis elevatis caiicellati, ultimus liris spiralihis sex 

 (injima ad peripheriam sita) cinctus, infra medium concentrice 

 tenuissiine striatus, lineis incrementi levibus sculptus ; apertura 

 parva, sublunata ; peristoma tenue, margine columellari paulum

Hab. Mount "Eabong, West Sarawak. 



The upper surface being cancellated and the lower smooth and 

 glossy, this species is readily distinguishable from the other 

 Bornean species of the genus Sitala. 



The oblique curved lines of growth are elevated, but closer 

 together than the spiral threads. 



38. Sitala ineantilis. (Plate III. fig. 15.) 



Testa minuta, conico-subglobosa, angustissime perforata, cornea, 

 pellucida, polita ; spira conoidea, ad apicem obtusa ; anfractus 

 5, convexiusculi, lente accrescentes, infra suturam anguste mar- 

 ginati, laves, ultimus depresse globosus ; apertura oblique lunata ;
