Proceeding of Bot. Soc. of Edinburgh Nov. 10th― 1859. Address by Mr Andrew Murray - says congenerous eye-less insects - not found in outer world - occur in caves of Carniola - Hungary - Pyrenees - Auvergne - Kentucky -

Again Æpus fulvescens, lives between high & low-water mark. A closely allied form of distinct genus Thalasobius testaceus lives in same situation in Chile.-

Quotes Paurus in Ant nests over world. – (N.B Wollaston better case of eyeless insect in Madeira & Teneriffe - identical. He must admit double creations.) Is going to publish paper on this subject in nest Edin. Phil. Journal.

[219v]

Are there any genera found in 2 or more caves, which have eyeless species in the caves & at same time seeing insects outside in the 2 or more countries?. If the blind insect belonging to the exclusively cave-genera, were identical in distant caves, it would be a very great difficulty.

As there is no Fish known in U. States which by blinding & other slight change wd make Amblyopes & as no reptile in Europe which wd make Proteus, so I suppose some genus of insects inhabited two Worlds & entered caves became blind & the seeing species became extinct in open country.

The blind insect are wrecks of ancient life.
