LAND- AND FRESHWATER SHELLS. 151 



This species approaches Helix solorensisj but the latter 

 is larger, more umbilicatecl , nearly smooth and without 

 teeth in the aperture; it resembles very much H. Reinga 

 Gray (Reeve, Conch. Icon. fig. 772), but the aperture is 

 rounded and not triangularly lunar. The sculpture in H. 

 Reinga is called obliquely striated and no mention is made 

 of a second tooth on the outer lip. 



The specimens vary in shape and size and in the number 

 of the bands, which in some specimens are nearly limited 

 to the sutural and peripherical ones; in other specimens 

 the whole shell is banded. 



10. Amphidromus latestrigatus , n. sp. 



Shell sinistral, ovately-conical, nearly smooth, perforated , 

 apical whorl blackish-brown, next whorl rose-colour, the 

 following whorls are white, then pale yellow, last whorl 

 darker yellow, total number of whorls about 6^/3; they 

 are slightly convex , the four last with broad brown flames , 

 which on the last whorl become greenish gray and are 

 often confluent towards the base, sutures with a narrow 

 white margin, accompanied by a blackish one (wanting 

 in one specimen); aperture ovately oblong, angular above, 

 rounded beneath, occupying less than half the length of 

 the shell, bluish white interiorly ; lip moderately expanded ; 

 columella nearly straight, like the lip dark rose-coloured, 

 margins connected by a thin callosity of the same colour.

Localities: Massoe, central South East Soemba; near 

 Waingapoe , Soemba. 



This species differs from all the allied ones, by the 

 broad flames and the fine rose-colour of the aperture ; this 

 last peculiarity is also found in A. suspectus Martens , A. 

 Annae Martens and in the next species, but they differ in 

 so many other respects , that they may be easily recognized.
