Shell conically-elongate, solid ; whorls 6, slightly rounded, mar- 

 gined above ; aperture elongately-ovate ; lip subreflected ; columella 

 short, obliquely twisted, with an expanded callus ; suture slightly im- 

 pressed ; striae numerous, longitudinal, oblique ; colour white with 

 yellow transverse bands, or yellow with white transverse lines, and 

 longitudinal chestnut-coloured stripes. 



This species cannot be confounded with any other than the A. sub- 

 virens in one of its varieties, the distinctive marks of which are given 

 under that species.

 dextrorsa, solida, ovato-conica ; anfractibus 6, rotundis, supra 

 marginatis; sutura bene impressa ; labro subreflexo, interne in- 

 crassato ; apertura ovata ; columella brevi, fortiter dentata, cum 

 callo expanso umbilicum obtegente ; colore ferrugineo-fulgente,

Shell dextral, solid, ovately conical ; whorls 6, rounded, margined 

 above ; suture well-impressed ; lip lightly subreflected, thickened 

 within ; aperture ovate ; columella short, strongly dentate, with an 

 expanded callus covering the umbilicus ; colour of a bright reddish 

 brown, with a white band accompanying the sutures ; columella and 

 lower and outer portion of last whorl white. 



This species passes into the white variety of A. t&niolata of Pfeif- 

 fer ; but in the latter species the mantle of the animal is of a dark 

 slate-colour, and in the above species it is of a light flesh-colour. The 

 markings are characteristic of the species, the rusty hue varying in 

 intensity and quantity of surface covered in different specimens. 



K 70. ACHATINELLA VARIABILIS (PI. XXIV. fig. 70). A. testa si- 

 nistrorsa vel dextrorsa, conico-acuminata, polita, nitente ; an- 

 fractibus 6, rotundis, superne submarginatis ; apertura subovata ; 

 columella brevi, cum tuberculo forti coloris rosei munita ; labro 

 expanso, acuto ; colore testte vario, albo,flavo, nigro, etc., piano 

 vel cum cingulis sex minusve, colorum diversorum in anfr. ul- 

 timo.

Hab. Ranai. 



Shell sinistral or dextral, conically acuminate, polished, shining ; 

 whorls 6, rounded, lightly margined above ; aperture roundly ovate ; 

 columella short, armed with a strong tubercle of a roseate colour ; 

 lip expanded, acute ; colour of shell white, yellow, black and other 

 shades, plain or with from one to six bands of various colours on the 

 last whorl. 



This is the most variable species in markings that has yet been 

 found among the Achatinellce. It is extremely difficult to find two 

 (except the plain ones) precisely alike in this respect.
