Only a single specimen obtained. Beneath the peripheral 

 red line the colour for a short space is darker than the rest

 pale zone. The tine granular sculpture extends over the 

 entire surface, with the exception of a small space around 

 the umbilicus.

 press!, superiores tres spiraliter minute punctato-striati, striis

 quent es minus convexi, oblique striati, ultimus ad peripheriam 

 acute carinatus, haud descendens ; sutura carina marginata ; 

 apertura angulato-lunata : peristoma tenue, simplex, marginc

The generic position of this species is rather uncertain. 

 All the four specimens have a somewhat immature aspect. 



Chloritis (TricJwcJiloritis) conjecta. 



Testa depressa, suborbicularis, late umbilicata, cornea, subpellucida, 

 incrementi lineis tenuibits striata, undique conspicue punctata ;

 subprofuncla sejuncti, ultimus antice valde descendens, pone aper- 

 turam constrictus, circa umbilicum obtuse angulatus ; apertura 

 lunata, obliqua ; peristoma albidum, vel pallide rufescens, tenue,
