OF MEEGUI AND ITS AECHIPELAGO. 



163 



S. gabata. 



Mergui. 



Diam. maj. 18-20J, alt. 9-10 

 millim. 



The upper whorls rising each a 

 little above the following. 



Pale horn-colour, the keel some- 

 what darker brown, also in 

 the last whorl ; no peculiar 

 coloration of the suture. 



Beflected part of the peristome 

 narrow, about 1 millim. 



Umbilicus with nearly perpen- 

 dicular walls. 



So pilisparsa. 

 Minahassa. 



Diam. maj. 23, alt. 10. 



The three upper whorls not 

 rising one above the other. 



Pale greenish grey, the suture 

 marked with a chestnut- 

 brown band, the keel of the 

 last whorl of the same colour 

 as the rest of the shell. 



Eeflected part of the peristome 

 broad, about 2 millim. 



Umbilicus with more sloping 

 walls. 



Helix pilisparsa is beset with short hairlets on its upper 

 and lower face. Grould mentions no hairs in his description 

 of S. gabata ; and Anderson's specimens have no hairs, but 

 they are all somewhat worn, and they show some roughness, 

 which may be due to the presence of hairs in the fresh state. 

 Philippi describes his S. merguiensis as " pilis sparsis brevibus 

 obsita."
