Soc. 1881, p. 282, pl. xxxiii. fig. 10. Hab. Nyasaland (H. H. Johnston); Lsambara (Kirk); Zanzibar, Tanga, &c. (Martens). 39. ACHATINA CRAVENI Smith. (Plate XXXV. figs. 1, 2.) Achatina kirkii, Smith, Ann. Mag. Nat. Hist. 1880, vol. vi. p. 428 (name preoccupied). Achatina craveni, Smith, Proc. Zool. Soc. 1881, p. 283, pl. xxxiii. fig. 11; Martens, Weichth. Deutsch-Ost-Afrikas, p. 91. Hab. 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. O n the contrary, other specimens are uniformly greenish yellow without any striping at all. 40. ACHATINA GLAUCINA. (Plate XXXIV. figs. 2, 3.) Achatina glaucina, Ancey, M S S. Testa ovato-fusiformis, fiavescens vel rufescens, concolor, vel in-terdum supra spiram strigis rufis obliquis undulatis obscure picta; spira conica, ad apicem obtusa, lateribus convexiusculis; anfractus 8, lente accrescentes, convexiusculi, superiores treslceves, cceteri granulati, granulis in anfr. ultimo infra medium plus minus obsoletis; apertura glaucina vel cceruleo-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, convexiusculi, 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 truncata. |
