ACHATINA, S.-G. LEPTOCALA. 75 



times ornamented with indistinct wavy reddish-fawn st.riae. 

 The growth-stria 1 are irregular and inconspicuous to the 

 naked eye. Adolf d'Ailly has suggested that the species 

 be referred to this group.

3. A. RAPFRAYI (Jousseaume). 



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

 delicately striatulate at the suture; buff-corneous, painted 

 with longitudinal straight or wavy rufous flames, interrupted 

 at the periphery, base broadly banded with roseate. Whorls 

 7, a little convex, the last slightly wider, a little more than 

 one-third the total length. Columella somewhat straightened, 

 compressed, obliquely truncate at the base. Aperture oblique, 

 truncate-oval, the peristome simple." 



Length 26, diam. 12, aperture length 10, width 6 mm.

 p. 172. 



On the intermediate whorls the flames widen towards the 

 lower suture ; on the last whorl they are more irregular, and 

 widen or coalesce to form large brown spots on the convexity 

 of the whorl, in which the flames abruptly terminate along 

 a line which is an exact continuation of the suture. The 

 base, up to the yellowish belt below the spots, is nearly 

 uniform vinous red. 



This species has not been figured. The above description 

 and notes are from Jousseaume, and show the shell to be 

 very close to L. grandidieriana Bgt. There seems to be little 

 aside from size and locality, to separate the two forms ; 

 the smaller size coupled with the less number of whorls prob- 

 ably indicating that raffruyi was based on a younger shell 

 than grandidieriana.
