 p. 340; xxix, 1881, p. 197, pi. 8, f . 1 ; and in Grandidier, 

 Moll. Madag., pi. 20, f. 3. 



A thin, white shell, almost totally denuded of cuticle when 

 adult, and with no trace of flames or streaks except the slight 

 cuticular shreds. Some specimens have a much more arcuate 

 columella than the type. 



42. A. FULVA (Bruguiere). 



This species differs from the preceding two [zebra and 

 achatina], with which it has great affinity, (1) in that the 

 shell, though composed of the same number of whorls, is a 

 little more lengthened and less ventricose; (2) the striae are 

 all longitudinal, inconspicuous, and without any appearance 

 of transverse striae; (3) the aperture is shorter than half 

 the shell, the left lip is very thin and not colored, and the 

 columella is a beautiful incarnate tint, as in the B. achatina, 

 but a little less intense. Finally, it differs by the color of 

 the exterior, which is fallow throughout, without mixture of 

 any other color. All other parts of the shell conform to 

 those of the two species preceding. I do not know the 

 habitat (Brug.).

The salient features of this species, as stated by Bruguiere 

 uniform fallow color, absence of spiral striae, and roseate 

 columellar margin have not yet led to its identification with
