Mr. G. H. K. Thwaites read a paper, being a notice of the dis- 

 covery of Grimmia orbicularis, a moss new to Britain, which was 

 found by him upon St. Vincent's Rocks, Bristol. The foliage is not 

 distinguishable from that of Grimmia pulvinata ; the capsule however 

 is abundantly distinct, being globose instead of ovate, and having a 

 conical instead of a rostrate operculum. Both species grow upon St. 

 Vincent's Rocks, and are sometimes intermingled, but each retains 

 its peculiar characteristics, so that Grimmia orbicularis cannot be con- 

 sidered a variety of G. pulvinata. Specimens of the former species 

 accompanied the paper.

 List of Plants found in the neighbourhood of Banbury, Oxfordshire,
