76 COCHLITOMA. 



glossy, smooth, polished, seen to be delicately striate under 

 a very strong lens; opaline, the lower part of the last whorl 

 is vinous-chestnut, and the whorls (except the first) are ele- 

 gantly ornamented with narrow black-chestnut lines ter- 

 minating in wide spots of the same color at the periphery. 

 Spire tapering, the summit obtuse. Whorls 9, a little con- 

 vex, regularly and slowly increasing, separated by an im- 

 pressed suture; the last whorl convex, slightly over one- 

 third the alt. Aperture oblique, relatively small, irregularly 

 ovate, violaceous and showing the spots inside, whitish at the 

 edge ; peristome unexpanded, acute. Columellar margin short, 

 curved, at the base contorted and abruptly, strongly trun- 

 cate. Parietal callous vinous. (Bgt.). 



Length 36, diam. 15.5, alt. aperture 13, width 7 mm. (Bgt.).

 Leroy) ; Ussambara (Conradt, W. Schmidt).

 1889, p. Ill, pi. 6, f. 9, 10. Achatina g., v. MARTENS, Bes- 

 chalte Weichthiere D. Ost-Afr. p. 93. Achatina nitida v. 

 MART., Conch. Mittheilungen iii, p. 7, pi. 43, f. 1, 2. (1896). 



The color-pattern is characteristic, no less than the total 

 want of granulation and the glossy surface. Figs. 6, 7 of pi. 

 42 are copied from Bourguignat's figures of his type. Figs 

 1, 1 of pi. 40 represent the synonymous A. nitida. 



Perhaps this is to be regarded as a variety of A. raffrayi, 

 with which it agrees in coloration. It is larger, more solid 

 and has two more whorls.

 authors. 



Ovate or oblong shells, with the apex obtuse and of the 

 bulbous or globose type, the initial whorl smooth, the rest of 

 the protoeonch decussate-granose, this sculpture extending 

 without interruption upon the adolescent and usually the 

 adult stages ; aperture as in Achatina, the columella distinctly 

 truncate at its base.
