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

 taken another species (apparently new) of the same genus (*), this 

 latler occurring in a hot-house, Rew Gardens, London, where, as 

 well as in Xorthumberland, T. Stebbingi is also found.

This small species was described by Professor Sars from Norway 

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

 evidently widely distributed but no doubt overlooked on account of 

 its small size. Mr. Patience finds it commonly in the Glyde dis- 

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

 ises, viz., Edinburgh, London, and in the Gounties of Northumber- 

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

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

 the sea-shore.
