49. Melania [Melanoides] torquata. 
Melania torquata, v. d. Busch, Abb. I, 1845, Java ;=M. terebra, Benson, 
1836, Sylhet [not M. terebra, Lesson, 1830, or M. terebra, Busch, . 
1845). 
10 Sylhet [types of M. ¢erebra, Bs.] ; ex c. Asiatic Soc., Bengal, and 
Colonel G. B, Mainwaring. 
&0. Melania [Melanoides]} asperata. 
Melania asperata, Lamarck, Hist. Anim. s. Vert. V, 1822, South America? 
I consider Reeve’s fig. 18, “ M. circumstriata from Borneo,” 
as quite distinct and probably a form of M. herculea, Gld. 
8 Near Manila; coll, Baron F, von Richthofen. 
This apparently constant dwarf form more nearly resembles 
M. Brot’s pl. 9, fig. 4, If. perfecta, Mous., from Celebes, than 
his pl. 8, fig. LA, typical M. asperata,—indeed, it may prove to be 
the former species. Long. 35, diam. 14; another 22, 103 mil. 
Living with it was the following subvariety distinguished by 
its smooth appearance, having spiral, subobsolete sulcations on 
the last whorl only. 
subvar. sublevigata. 
4 Near Manila; coll. Baron F. von Richthofen. 
Three or four irregular ridges on the last two whorls. The 
upper ones smooth [or nearly so]. 
Long. 56, diam. 22 mil.; whorls 53.
