occurred under stones, and accompanied by Microtyphlus schaumi and Amaurops aubei. It is common under

The species of Anommatus, like those of Lyreus, Langelandia, and Aglenus, allied genera and 
equally blind, live under the bark of damp wood adhering to the soil, or under stones which 
cover rotten wood; they are terricolous, but none of them is peculiar to caves, though one species 
of Anommatus was observed by H. Miiller in a cave in Carniola (Bedel, p. 63). 
Family Pselaphidae. 
This family, like the Scydmenidge, comprises a certain number of genera or species which live 
under stones or in the soil, whose mode of life is ultimately analogous to that of the cave forms 
(Bedel).
