 ascendente, subcolumellari immersa ; plicis palatalibus 7, superiore 

 valde elougata, 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. ; apert. (oblique) longa 8, lata 7 mill. 



Habitat ad ripas fluvii Attaran, non procul ab urbe Moulmein. 



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

 Gordon in the same locality as Opisthoporus Gordoni, Helix 

 brachyplecta, and H. Gordonia — shells which escaped the ob- 

 servation of former collectors in that rich district. The bul- 

 bous pupiform figure of the shell at once distinguishes it from 

 CI. Philippiana, 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.

B. testa rimato-perforata, oblongo-conica, solidiuscula, oblique irre- 

 gulariter plicatulato-striata, epidermide spiraliter confertissime 

 striatula, castanea, strigis obliquis, sutura, basi apiceque albidis ; 

 spira elongato-conica, apice obtusiusculo, sutura impressiuscula, 

 nonnunquam marginata ; anfractibus 7, convexiusculis, ultimo ad 

 basin compressiusculo, antice vix ascendente ; apertura subobliqua, 

 anguste pyriformi, intus castanea, peristomate sensim dilatato, vix 

 reflexiusculo, albido, marginibus remotis, non conniventibus, co- 

 lumellari lato, callo obliquo superne castaneo junctis. 



Long. 20, diam. 7 mill.

Found by Mr. F. Layard in the district of Upper Ourah, in 

 Ceylon. Its nearest ally is Bulimus proletarius, Pfr., which was 

 taken by Mr. Layard at Bootelle and Kaluganga. 



10. Opisthoporus Gordoni, B v n. sp. 



O. testa late et concave umbilicata, depressa, discoidea, confertim

 tata ad peripberiam ornata ; spira planata, apice non elevato ob- 

 tuso, sutura profunda, demum canaliculata ; anfractibus 5, grada- 

 tim accrescentibus, convexis, ultimo rotundato, antice descendente,
