Melania asperata, Lamarck, Hist. Anim. s. Vert. F, 1822, South America ? 



I consider Reeve's fig. 18, " M. circumstriata from Borneo," 

 as quite distinct and probably a form of M. herculcea, Gld. 



8 Near Manila ; coll. Baron F. von Richthof en. 



This apparently constant dwarf form more nearly resembles 

 M. Brot's pi. 9, fig. 4, M. yerfeda^ Mous., from Celebes, than 

 his pi. 8, fig. 1 A, typical M. asperata, indeed, it may prove to be 

 the former species. Long. 35, diam. 14; another 22, 10| mil. 



Living with it was the following subvariety distinguished by 

 its smooth appearance, having spiral, subobsolete sulcations on 

 the last whorl only. 



subvar. sublsevigata.

Three or four irregular ridges on the last two whorls, The
