niy friend Mr. Patience from Scotland, whilst I hâve only recently

 well as in Nortliumberiand, T. Stebhingi is also found.

 p. 474, Dec. 1906. 



Thiâ smali species was described by Professor Sars from Norway 

 in 1897 and was rediscovered in Britain last year (1906). It is 

 evidenlly widely dislributed but no doubt overlooked on account of 

 ils smali size. Mr. Patience finds it commonly in the Glyde dis- 

 trict where l hâve also found it in addition to the following local- 

 ities, viz., Edinburgh, London, and in the Counties of Northumber- 

 land, Durham and Yorkshire. It occurs chiefly in gardens though 

 I hâve seen it on many occasions in the open country.
