PUPISOMA. 33 



tates to question their endemicity in both, hemispheres; yet 

 the possibility of transportation by commerce is not to be 

 ignored. 



The following forms, hueense, philippinicum, pulvisculum 

 (no. 9), circumlitum and steudneri appear to be synonyms. 

 Further material may perhaps reveal differences ; I have seen 

 typical material of philippinicum and circumlitum only, and 

 it is hardly safe to synonymize the others without knowledge 

 of the microscopic sculpture, which the descriptions do not 

 give. The original descriptions follow. 



11. Pupisoma hueense (Wattebled). PI. 3, fig. 12. 



Shell very minute, subrimate, conic, thin, somewhat pel- 

 lucid, slightly striate, somewhat greenish-corneous. Spire 

 turbinate, the apex obtuse. Suture impressed. Whorls 3%, 

 gradually increasing, strongly convex. Aperture oblique, 

 subrotund. Peristome simple, dirty whitish, the columellar 

 margin a little thickened, outer margin acute. Alt. 2, diam. 

 11/2 mm. (WatteUed). 



Annam: Hue, under dead leaves in thickets (Dorr). 

 Helix hueensis WATTEBLED, Journ. de Conchyl., vol. 34, 

 1886, p. 57, pi. 4, f. 3. 



Not seen. Probably a synonym of P. orcula. 



12. Pupisoma philippinicum Mlldff. PL 2, figs. 3. 



Shell rimate, globose-conoid, thin, finely striatulate, cor- 

 neous ; spire convexly conic, the apex obtuse. Whorls 4, quite 

 convex, the last rounded, slightly descending in front. Aper- 

 ture diagonal, subcircular ; peristome thin, very slightly ex- 

 panded, the columellar margin dilated, triangularly reflected. 

 Alt. 2, diam. 1.7 mm. (Mlldff.). 



Philippines: Montalban and Manila, Luzon (Moellendorff). 

 Cebu, on bushes and shrubs (Koch). Moluccas: Hitulama, 

 northern Amboyna (A. Strubell). Savu I., 011 orange trees 

 (Everett). Caroline Is. : Ponape (Kubary).
