Great success has attended Professor Brady's hunts for 

 woodlice during the last few months in Westmorland and 

 Durham. He has added two species to our fauna, and met 

 with others previously known in our Islands only from a 

 single far removed locality. 



HapJophthalmus danicus, Budde-Lund. 



This interesting species, recorded in 1899 as occurring in 

 the garden of A. M. N. at Berkharapsted, Herts, has just 

 been found by G. S. B. at Humbledon Hill, near Sunderland. 



HapJophthalmus Mengei^ Zaddach. 



This was added to our fauna last year, having been found 

 by A. M.N. in Co. Clare, Ireland. G. S. B. has this autumn 

 added it to the English fauna from Fulwell Quarry, near 

 Sunderland. 



Trichoniscoides albidus (Budde-Lund).

A Trichoniscus taken by G. S. B. at Carley Hill Quarry, 

 near Sunderland, has been compared with co-types of 

 Trichoniscus pyg')nceus^ G. O. Sars, and specimens of 

 Trichoniscoides alhidus, for which we are also indebted to 

 our kind friend Professor Sars. In general appearance 

 these two species seem to greatly resemble each other, but 

 the Sunderland specimens agree with the latter in the 

 shorter and wider form of the raaxilliped, in the blunt 

 stumpy spines of the last two joints of the peduncle of tlie 

 antennae, and in the more strongly tuberculated head and its 

 lateral lobes and of the body-segments generally. On the 

 oiher band, the flagellum of the antennae is three-jointed, 

 and Sars represents it in this species as four-jointed, while 

 that of Trichoniscus pygmoeus is three-jointed. On turning.
