414 THYSANURA, 



CASE water. Found under young sea weed and between layers of shale 

 xxi. 



between tide marks in the Firth of Forth, and along the coast 



both to the north and south, also at Kinsale in Ireland, and 



on the French coast, occurring no doubt wherever there is a 



suitable habitat. 



LiPURA STILLICIDII (^r/z.). 



A white species, very common in the Adelsberg caves. Either 

 it or a closely allied species also lives in the Mitchelstown cave 

 near Cahir, in Ireland. It is eyeless ; for although there are two 

 rows of seven prominences in the place behind the antennas, and 

 before that where the eyes should be, which have been called 

 eyes, we think that their very unusual profusion in a medium 

 where no other insect has any eyes at all, or any use for them, is 

 not favourable to the idea of their being eyes. They also occur in 

 other species where eyes are present. 



No. 22. Anoura muscorum (7>;;z/.).— 22. Magnified sketch of ditto. 



This is another of the non-saltatorial genera, 

 and it is the only one of the Collembola that 

 has no mandibles. It is suctorial. The species 

 is of a dark purple colour, and is found under 

 wood and bark. It is common. 



Anoura granaria {Nic). — 23. Magnified sketch of 

 ditto. 



This is of an alabaster white, and has occurred 

 under detritus in France and England, but it 

 has not been often met with. These are the 

 only species of Anoura that have been found in Britain. 



Anoura n.uscorum.
