and hence more easy to be seen. The pores observed not only 

 on this beautiful moss, but also on other forms belonging to the 

 same group, LeucobryaceWy as also on different JEucalyptce^ Syr- 

 rTKypodonteSy Calymperes^ &c., are not very like those on SpJiagna^ 

 being of very irregular form, without any trace of a thickened 



circumscribing border, and are not found in every cell. 



If we put the object between glasses in the same iodine solu- 

 tion, it will remain unaltered for several years/ These observa- 

 tions have already been published in my essay on the Bog-Mosses 

 (1862). 



YII. The British Dicranum sfrictum. 



I have received from Mr. Wilson a specimen of " Dicranum 

 strictum=D. thraustum^ Schpr. ? " gathered on old oat rails, 

 Staffordshire, 1864, by Mr. Bloxam. This specimen belongs to a 

 moss already named, in 1850, D. thraustoj^lyllum (Muse. Pyren. 

 No. 257, " wood between Pau and Gan ") by the acute Mr. Spruce, 

 and later, by SuUivant and Lesquereux, Campylopus viridis. It 

 is exceedingly rare in fruit, this having been found only in Bavaria 

 by Mr. Arnold (only one capsule), and in Finland by Dr. Norrlin 

 (about twenty capsules). Its synonymy is- as follows :

YIII, A British Seligeria. 



Since the publication in 1860 of 'Synops. Muse. Eur.* by Prof. 

 Schimper, in which important work four species of Seligeria are 

 described, the genus has been enriched by no less than four new 

 forms, all from the north of Europe — viz. S. paitcifolia (Dicks.) 

 Carruth., S. diversifolia, S. crassinervis, and >S'. acutifolia^ Lindb.,
