146 Mr. E. A. Smith on Land- Shells from the 



late lunata, concolor, in medio zonata efc supra lineata ; peristoma 

 tenue, margins columellari breviter expanso et refiexo. 

 Diam. maj, 28 millim., min. 24|, alt. 21. 



Hah. Bauluan Islet, Selayar group. 



Allied to X. nemorensis, but spire less elevated, lines of 

 growth finer, and colour different. The fine spiral brown 

 lineation is peculiar and the suture is bordered beneath with a 

 fine blackish line. The coloration is not unlike that of Xesta 

 Stua?'tice, but the form is more depressed and the sculpture 

 finer. 



Xesla halaoensis. (PI. X. fig. 4.) 



Testa perforata, depresse turbinata, mediocriter tenuis, cinereo- 

 fusca, punctis pellucidis irregulariter picta, inferne lineis con- 

 centricis albidis plus minus distinctis ornata, vix nitida ; anfractus 

 6, convexiuscuh, subleute accrescentes, lineis incrementi tenuibus 

 obliquis arcuatis sculpti, sutura simplice sejuncti, ultimus ad 

 peripheriam rotundatus, antice vix descendens ; apertura late et 

 oblique lunata, intus concolor albo lineata ; peristoma tenue, 

 margine columellari ad insertiouem breviter dilatato et refiexo. 



Diam. maj. 33 millim., min. 28|, alt. 22^. 



Hah. Kalao Island. 



Allied to X. inquinata from Java in colour and general 

 appearance, but quite distinct. The wliorls are more convex, 

 the last not subcarinate, and the surface is not spirally 

 sculptured. 



Trochomorpha jampeana. (PL X. figs. 5-5 b.) 



Testa orbicularis, carinata, late umbilicata, fusca, baud nitida, lineis 

 incrementi tenuibus sculpta ; spira depresse conoidalis, ad apicem 

 obtusa ; anfract. 6, lente accrescentes, leviter convexiuscuh, supra 

 suturam anguste castaneo carino-marginati, ultimas cseteris minus 

 convexus, acute compresse carinatus, baud descendens ; apertura 

 securiformis ; peristoma tenue, margine inferiore levissime in- 

 crassato. 



Diam. maj. 15 millim., min. 14, alt. 5. 



Hab. Janipea Island. 



Rather like T. Lamontt, Brazier, from New Guinea, but 

 less acutely keeled, more narrowly margined at the suture, 

 browner, more opaque, and with slightly more convex whorls. 

 The umbilicus also is deeper and less open. T. gorontalensis, 

 Martens, has the periomphalium more angulated and a whorl 

 less in shells of the same size ; it is also smoother and rather 

 glossy.
