Type, Clausilia pliilippiana, Pfeiffer. 



Range. Burma. 



" Shell with but few whorls, usually live or six, and of a 

 peculiar more or less oval form with a very blunt apex. Lunula 

 wanting, palatal plaits as in Phaedusa. 



" The known shells of this section are solid deeply coloured 

 Clausiliae, smooth or with very slight sculpture. So far as is 

 hitherto known, the type is peculiar to Martaban and Tenasserim."

Original description : — " C. testa sinistrorsa, vix rimata, oblongo- 

 obovata, pupiformi, regulariter oblique striata, rubenti-ferruginea ; 

 spira obovata, super ne veutricosa, versus apicem obtusum con- 

 camerata, sutura impressa ; aufractibus bh, convexiusculis, primis 

 rapideaccrescentibus,antepenultimo tumido, penultimo angustiore, 

 pone aperturam obliqua, oblique auriformi, peristomate continuo, 

 margine late expanso, reflexiusculo, albido-rubente, lamella 

 superiore acuta, prominente, longe, intus intrante, spirali, infera 

 forti, oblique spiraliter asceudente, subcolumellari immersa ; plicis 

 palatalibus 7, superiore valde elongata, late erecta, intus cum 

 lamella superiore rimam angustam efformante, 6 inferioribus 

 brevibus, subparallelibus, luuella nulla. 



"Diam. anfract. antepenvxltimi 9, ultimi supra aperturam 5, 

 axis 23 mill. ; ap. (oblique), longa 8, lata 7 mill." (Benson.) 



Hah. Burma : Banks of the Attaran Eiver, near Moulmain. 



" This most singular form in the genus was found by Col. 

 Eobert Gordon. The bulbous pupiform figure of the shell at 

 once distinguishes it from CI. philippiana, Pfr., an inhabitant of 

 the Parm Caves, as wnW as from any other known species. The 

 upper lamella runs spirally up the aperture, forming a narrow slit 

 between it and the upper knife-like plica." {Benson.)
