Species 12. (Mus. Cuming.) 

 P.\KTULA RUBESCENS. Part, testd acuminatO'oblongd, 

 crassiimculd, sinistrorsd, compresse umhilicatd, anfrac-

 The pink Partula. Sliell acuminately oblong, rather 

 tkick, sinistral, compressly umbilicated, whorls six in 

 number, smooth, somewhat rounded, lip and colu- 

 mella broadly reflected ; pink, red-brown towards the

This species, of which Mi-. Cuming possesses three 

 specimens, is larger than P. rosea, and of more solid acu- 

 minated growth. 



Fig. 13 a, b. (Mus. Cuming.) 

 Paktula Otaiieitana. The shcUs here figured re- 

 present the sinistral and more slender state of the above- 

 named species, described in the preceding plate. This 

 variety has been erroneously labelled in collections P. aiis- 

 tralis, which is only another name of P.faba.

Hab. Sandwich Islands (on plants); Quoy and Gaimard. 



There are two very distinct varieties of tliis species ; one 

 of pale yellow tipped with rose, the other of an uniform 

 ash-colour, in which the white sutures are more conspi- 

 cuous.

Only the upper edge of the chestnut baud is left visible 

 in the first four whorls of this very elegant and charac- 

 teristic species.
