FULTON : NEW SPECIES OF LAND SHELLS. 101 



gined, deflected backwards somewhat at basal termination, columellar 

 portion gradually widening to point of insertion, margins connected by a 

 thin transparent callus. 



Maj. diam. 9 ; alt. 32 millim. 



Hah. — Brazil. 



This bears great resemblanc3 to the figure of 0. ivilli, Dohrn, but 

 according to Dohrn's description that species is " delicately and sharply 

 striate longitudinally,'''' a character not present in our species. From 

 0. nasutus, Mts., it can be distinguished by its strongly malleated surface 

 and the absence of the rather conspicuous white spiral hair-lines 

 seen in that species. 



Leptopoma placidum, n.sp. 

 PI. ix, fig. 7. 



Shell almost imperforate, subconical, thin, pellucid, light yellowish 

 colour, ornamented by numerous somewhat interrupted narrow golden- 

 coloured spiral bands, lower whorls with microscopic spiral waved striae, 

 middle whorls with four more conspicuous thread-like keels ; whorls 5^^, 

 moderately convex, last rounded ; aperture very oblique, subcircular, 

 opaque white for a short distance within, then transparent ; peristome 

 expanded except at columellar margin which is much thinner and almost 

 straight ; operculum normal. 



Maj. diam. 10; alt. 11 millim. 



Hab. — S. Flores Island, lowlands under 500 ft. (Everett). 



The narrow conical form of this species and the almost closed umbi- 

 licus distinguishes it at once from any other species known to me from 

 that region. 



Leptopoma albicans, n.sp. 

 PI. ix, fig. 5. 



Shell globosely conic, narrowly perforate, white, sometimes with a pale 

 reddish band at 1h periphery continued at suture above, apex reddish- 

 brown, with usual microscopic waved striae, on middle whorls about 

 seven or eight spiral threads ; whorls 5|, moderately convex above, last 

 whorl subcarinate in front, last half rounded ; aperture somewhat oblique, 

 subcircular ; peristoma white, narrowly expanded all round, margins 

 joined by a very thin callus ; operculum normal. 



Maj. diam. 10 ; alt. 11 millim. 



Hab. — Sumba Island (Everett). 



This neat little species of the same gross dimensions as the last 

 described is nevertheless quite distinct, its spire is larger in proportion, 

 its paristome smaller and less oblique, and it differs also in coloration 

 and the carination of its last whorl.
