SALVAGES. 207 



The European T. truncatula, which is locally abundant on the 

 tide-washed rocks in Madeira, has been obtained by the Baron 

 Paiva, both in its costate and comparatively unsculptured 

 phases, from the Great Salvage, where he records that it was 

 met with in tolerable numbers (and particularly under the form 

 to which I have already alluded, vide ante p. 280, as the 

 '/8. Iwvigata ' ) at the ' Furna de Nordeste.'

As already stated at p. 281 of the present volume, this mi- 

 nute European Assiminea was obtained in abundance by the 

 Baron Paiva from the Great Salvage, where it would seem to 

 occur, much as it does at the Canaries, Madeira, and elsewhere, 

 adhering to the large masses of rock which are washed by the 

 tide. Its very diminutive bulk and rounded-ovate contour, ad- 

 ded to its nearly unsculptured surface, solid substance, pallid 

 hue, and perfectly edentate aperture, will suffice to distin- 

 guish it.
