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



Helicostyla (Corasia) subtenuis. (PI. X. fig. 8.) 



Testa depressa, orbicularis, carinata, anguste umbilicata, alba, infra 

 zonis paucis subpellucidis indistinctis ornata, lineis incrementi 

 Bculpta, supra paulo malleata ; spira subplana ; anfractus 4|, vix 

 convexiusculi, penult, punctatus, ult. ad peripheriam acute 

 carinatus, supra et infra carinam impressus, infra convexus, 

 antice ad labrum vix descendens ; apertura securiformis, alba, ad 

 carinam linea opaca alba ornata ; peristoma tenue, marginibus 

 distantibus, superiore anguste expanse, inferiore latius reflexo, 

 ad insertionem dilatato, umbilicum semiobtegente. 



Diam. maj. 15 millim., min. 20, alt. 12. 



Hah. Selayar Island. 



A flattened depressed form like C. regince &c., and peculiar 

 on account of a slight umbilicus. 



Hypselostoma Everetti. (PI. X. figs. 9-9 b.) 



Testa minuta, aperte perspective umbilicata, fusca, striis incrementi 

 et spiralibus minute decussata ; spira parva, elata ; anfractus 4, 

 convexi, sutura profunda discreti, apicales magni, ultimus circa 

 medium concavus, supra et circa umbilicum obtuse angulatus, 

 antice solutus ascendens, aperturam versus scrobiculatus ; aper- 

 tura tuboeformis, dentibus pluribus intus armata ; peristoma 

 dilute rufescens, tenue, expansum, triangulari-rotundatum. 



Diam. maj. 3 millim., min. 2, alt. Ig ; apertura 1 lata. 



Hah. Kalao Island. 



In a natural condition all the shells are covered more or 

 less with agglutinated earth, which produces a rough irregular 

 appearance. There are five principal converging teeth within 

 the aperture, and a few smaller intermediate ones, none 

 reaching to the edge of the labrum. 



A species from Java in the British Museum, labelled 

 "ZT. Fruhstorferiy Bttgr.," somewhat resembles the present 

 form ; it is, however, larger, has the last whorl less freely 

 produced, is keeled at the middle, and the spire is more 

 elevated.

The type described by Mr. Fulton is here figured and is in 

 the National Collection.
