TYPE, Clausilia pliilippiana, Pfeiffer. 



Range. Burma. 



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

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

 wanting, palatal plaits as in Phcedusa. 



" The known shells of this section are solid deeply coloured 

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

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

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

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

 spira obovata, superne ventricosa, versus apicem obtusum con- 

 camerata, sutura impressa ; anfractibus 5J, convexiusculis, primis 

 rapide accrescentibus,antepenultimo tumido, penultimo angustiore, 

 pone aperturam obliqua, oblique auriformi, peristomate continue, 

 margine late expanse, reflexiusculo, albido-rubente, lamella 

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

 forti, oblique spiraliter ascendente, subcolumellari immersa ; plicis 

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

 lamella superiore rimam angustam efformante, 6 inferioribus 

 brevibus, subparallelibus, lunella nulla. 



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

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



Hob. Burma : Banks of the Attaran River, near Moulmain. 



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

 Robert Gordon. The bulbous pupiform figure of the shell at 

 once distinguishes it from Cl. pnilippiana, Pfr., an inhabitant of 

 the Farm Caves, as well 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.)
