 A curious little arachnid belonging to a group of an exotic 

 Order, about which little is really known. A few species 

 only have been met with of this group. The first recorded 

 species was of the Gen. nov. Nyctalops (Cambr.), of which I 

 received many years ago examples from Ceylon, recording 

 them as two species, Nyctalops crossicauda, andA'^. temiicorda, 

 and as forming a new family, Tariarides, of the Order Thely- 

 phonidea Ann. and Mag. N.H. s. 4. Vol. 10, p. i, PI. XXIL, 

 1878. These, however, proved subsequently to bethetwosexes 

 of the same species. The group has since been studied by the 

 late Dr. Thorell, also by Professor H. J. Hansen, of Copen- 

 hagen, and others. The present species is nearly allied to 

 Nyctalops, but differs in having eyes, whereas Nyctalops has 

 none. It was found in a hothouse in the Kew Gardens by
