Habitat Teneriffam ; in sylvaticis intermediis lecta. Etiam 

 in ins. Palma a cl. Shuttleworth (sed an vere ?) invenisse dicitur. 



Some examples of a Pupa which I took in the wood at La 

 Esperanza,near Laguna,in TenerifFe, pertain clearly to the species 

 which was described by Shuttleworth as the P. tceniata (stated 

 also to have been met with by Blauner in Palma) ; nevertheless 

 I am not at all sure that intermediate forms do not occur which 

 will be found to connect them by imperceptible gradations with 

 the somewhat variable P. pythiella,. However since normal 

 individuals do unquestionably differ, both in colour and sculp- 

 ture, from the latter, and since the two forms have been pub- 

 lished as specifically distinct, I will not attempt to unite them. 



Judging from the few examples to which I have access, the 

 P. toiniata may be said to have its volutions not quite so 

 flattened and also more strongly striated (being sometimes 

 indeed well-nigh costate) ; and its surface (instead of being of 

 an almost uniform concolorous brown) is of an olivaceo-corneous 

 hue, but conspicuously banded with a castaneous zone (imme- 

 diately above its suture) on the hinder portion of each of the 

 whorls.

The only Canarian examples which I have seen of this small 

 European Achatina (and which occurs likewise in the JNIadeiran 

 Group) were taken by myself, beneath stones, at the edge of a 

 Levada, or watercourse, on the western side of Palma, — namely 

 in the (but slightly elevated) calcareous district between Argual
