Eab. Nyika Plateau, 6000-7000 feet, and Malosa, Nyasaland, 

 6000 feet. 



These specimens are rather more coarsely sculptured than the 

 type, and some have the stripes more zigzag than as represented in 

 the cited figure. On the contrary, other specimens are uniformly 

 greenish yellow without any striping at all. 



40. Achatina glaucina. (Plate XXXIY. figs. 2, 3.)

 terdum supra spiram stric/is rufis ohliquis undulatis obscure 

 plcta ; spira conica, ad apiceni obtusa, lateribus conve.viusculis ; 

 anfractus 8, lente accrescentes, convexiusculi, superiores treslceves, 

 cceteri granulati, granulis in anfr. idtimo infra medium plus 

 minus obsoletis ; apertura glaucina vel ccerideo-albida, in ex~ 

 emplis adultis longit. totius | haud cequans, inverse auriformis ; 

 columella alba, leviter torta, anguste oblique truncata. 

 Longit. 66 millim., diam. maj. 29; apertura 30 longa, 16 lata, 

 Hab. Zomba. 



A smaller species than A. johnstoni, with a less tapering and 

 shorter spire, narrower whorls, and rather finer granulation. 

 The colour varies from uniform greenish yellow to rich brown, 

 but some specimens, chiefly of the latter variety, exhibit reddish 

 striping upon the spire. This kind of ornamentation, however, does 

 not appear to extend to the last volution. 



41. Achatina johnstoni, sp. nov. (Plate XXXIV. figs. 4, 5.) 

 Testa ovato-fusiformis, fiavescens, concolor, vel strigis undulatis vel 



zigzagformibus saturate rufo-castaneis picta ; spira elongata, 

 ad apicem obtusa ; anfractus 9, superiores tres Iceves, conveocius- 

 culi, cceteri convexi, incrementi lineis obliquis fortibus striisque 

 spiralibus numerosis ruditer granulati, ultimus infra medium 

 granulis fere evanidis ; apertura parva, inverse auriformis, 

 cceruleo-alba, strigis externis translucentibus ; columella leviter 

 arcuata vel rectiuscula, infra ad marginem alba, oblique trun- 

 cata.
