spots at the periphery, the base darkened. East African. 

 (Section Leptocallista Pils.).

1). 36x15.5 mm., with 9 whorls; Nguru Mts. and 

 Ussambara. A. grandidieriana, no 4. 



1. A. MOLLICELLA Morelet. 



See antea p. 29, where the description of this species is 

 translated. Ancey states (Nautilus xii, p. 92, Dec. 1898) that 

 on comparison with A. pulchella Martens he finds the two 

 to be identical specifically. Since the forms described by 

 Jousseaume and von Martens may prove to be distinguish- 

 able from mollicella, and have been figured, I give the de- 

 scriptions below. 



la. Var. petitia (Jousseaume). PI. 34, fig. 15. 



"Shell ovate-oblong, very thin, submembranous glossy, very 

 delicately striate spirally, buff-corneous ornamented with 

 wavy longitudinal yellow lines. Whorls 7, a little convex, 

 the last slightly wider, one-third the total length, columella 

 somewhat straightened, compressed, obliquely truncate 

 basally. Aperture oblique, oblong-ovate, the peristome simple. 



"Length 32, diam. 15, length of aperture 13.5, width 

 8 mm." (Jouss.). 



On the Congo above the N'toc river (L. Petit). Kamerun
