Mosses and Hepatics. — Mr. C. A. Cheetham and Mr. W. H. Burrell 

 write : — The bryology of the Tees district has been too well worked in the 

 past to allow many additions to the published lists, but a little moss on 

 the walls near Egglestone Abbey, Seligeria recurvata B. and S. (S. setacea 

 Lindb.), does not appear to be included. 



A growth of Ceratodon purpureus Brid. was seen with the excurrent 

 nerve of C. conicus Lindb., but not distinct enough to place under the 

 latter species. 



The next addition was on Widdybank, where Thuidimn Philiberti 

 Limpr. was gathered, it was the tripinnate form known as var. pseudo- 

 tamarisci. 



On the peat above, a patch of the very rare Tetraplodon Wormskjoldii 

 Lindb. provided the bryological thrill of the excursion ; it was in the best 

 possible condition of fruit. This moss was first gathered in Britain in 

 this locality by Mr. M. Slater in 1870, but considered to be a form of 

 T. mniodes B. and S. (T. bryoides Lindb.) ; later, in 1901, Messrs. Horrell 

 and Jones, whilst working at sphagna here, gathered and recognised it.
