6 There is no doubt that the Palcsmon anophthalmia Kollar, Sitz. Ber. 

 Akad. "Wiss., Wien, I, 1848, p. 137, from the cayes of Kompoljska and Portis- 

 kavez in Carniola is the same species as Troglocaris schmidti. As there is no 

 published description by Kollar, the name anophthalmia cannot be employed. 



7 C. americana is a somewhat doubtful species, but certainly it is closely 

 allied to C. typus.
