138 MELANIA BORNEENSIS. 



Alt. 55, lat. 22. Apert. alt. 19 V2, lat. 11 mill. 



Eah. Borneo , legit Schwaner. 



Of this species the Leyden Museum possesses only one 

 specimen , it differs much from any other Bornean species. 

 Moreover Dr. Brot knew no species , to which it could be- 

 long as a variety. 



5. Melania Midler i^ n. sp. 

 (Plate 2, fig. 5). 



Shell subulate, rather solid, olive-brown , often with purple 

 spots near the sutures and eventually with very obscure 

 punctuations. Apex nearly entire, whorls 7 — 8, nearly 

 flat, slightly contracted below the sutures, which are not 

 deep and slightly marginated. Shell smooth, with faint 

 lines of growth ; base rarely with very faint striae. Aperture 

 ovate, acute above, broadly rounded below, columella 

 curved and twisted ; interior of aperture bluish white. 



Alt. 40, lat. 13. Apert. alt. 14, lat. 7 mill. 



Hab. Borneo, Java, Moluccas; without locality, legit Muller. 



It is not without hesitation that I describe this and the 

 next species as new, as it seems rather strange , that species 

 with so wide a distribution should not have been described 

 before. The new species has much resemblance with young 

 specimens of M. uniformis Q. & G. , but the upper whorls 

 are smooth, it differs in colour and especially in the 

 characters of the aperture. It seems to be allied to M. 

 pantherina v. d. Busch and monile Mouss. , but is suffi- 

 ciently distinct by the colour, sculpture and aperture. 



6. Melania suhpunctata , n. sp. 

 (Plate 2, fig. 6). 



Shell subulate , rather solid , olive-brown , encircled with 

 interrupted brown lines, which are covered by the epider- 

 mis and therefore not conspicuous. Apex slightly eroded , 

 whorls 8 , slightly convex , with shallow sutures. Shell 

 smooth, shining, with lines of growth and eventually
