1893, p. 44. 



Original description : " Testa mediocriter umbilicata, sub- 

 turbinata, depressa, fulvo-cornea, tenuis, oblique striata; spira 

 conoidea, apice obtusa, sutura valde impressa. Anfr. 4 rotundati, 

 sensim accrescentes, ultimus vix descendens, subteres. Apertura 

 obliqua, rotundato lunaris ; peristuma simplex, rectum, marginibus 

 distantibus, sinistro baud reflexo. Umbilicum perspectivum. 



"Diam. maj. 2, min. 1|, alt. 1 mm." (Blanford.) 



Hob. India : near Pykara, Nilgiri Hills (Blanford}. 



" This shell in its form somewhat resembles a minute H. tapeina, 

 Bens., with more rounded whorls, deeper sutures, and a non- 

 expanded lip." (Blanford.} 



The species \vas not figured by Blanford, as he states that 

 unfortunately the specimen, forwarded to him by his brother for 

 that purpose, was crushed before it reached him. Hanley and 

 Theobald, however, give a representation of the shell, the specimen 

 figured probably originating from the same source.
