Generic Character. — See PI. 30. 



Specific Character. 



A. (div. 2.) testd prodiictd, sub-JIavd, J'asciis xiridihus flavisque ornatd ; 



apertiird ovato-rofu/idatd, albd ; labia exteriore medio inciso ; basi 



etnarginatd. 

 Ach. (div. 2.) Shell elongated, cream colour, with green and yellow 



bands ; aperture ovately rounded, white; outer lip notched in 



the middle ; base emarginate. 



A NEW and very delicate species, which may have been 

 overlooked as a variety of A.virg'inea, from which it differs in 

 the comparative length of the basal whorl, which in that is 

 remarkably short, in being a much more elongated shell, in 

 the mouth being oval, but above all, in having a conspicuous 

 notch in the middle of the outer lip, where the green band 

 commences ; the aperture (excepting the inner lip) is pure 

 white. It is in Mr. Dubois' possession, and its country 

 unknown. 



ACHATINA vittata, 

 Ribbon Achatina — middle figures. 



A. (div, 2. J testd orato-ublungd, crassd, albente, vittis nigris fuscisqite 

 angvstis ornatd ; aperturd ovatd, sub-contractd ; coliimelld tanfilm 

 non rectd ; basi subtruncatd. 



A. (div. 2.) Shell ovate-elongated, thickened, fulvous white, with 

 narrow black and hrown bands ; aperture oval, slightly con- 

 tracted ; pillar nearly straight ; base sub-truncated. 



Gualtieri, tab. 6. Jig. A. 



Although unnamed, this shell is obviously the same as 

 that figured by Gualtieri, who also describes it very tolerably. 

 This figure, however, is quoted by Gmelin and others for A. 

 virgiiiea ; from which shell it is quite distinct : it is a thickly 

 formed shell, the base slightly truncated, and the aperture 

 very narrow, and reddish brown ; the outer lip within is 

 thickened. From the same collection as the last,
