as usual. In the same wood grow the Hepatics, Metzgeria 

 furcata, the male plant with good antheridia ; Pellia epiphylla, 

 and Lophocolea heterophylla, covered with 'fruit.' 



Mr. Slater also records Leucodon sciuroides Schwgr. , and 

 the delicate and minute-leaved moss, Eurhynchium pumilhim 

 Schimp. 



Outside the wood on a grassy slope grow r Eurhynchium 

 crassinervium B.&S., in two states, one being- the large form 

 with the nerve often forking, and the other a smaller form on 

 a mound of bare soil ; a wide-leaved and robust form of 

 Ceratodon purpureus Brid., and Grimmia apocarpa Hedw.

On the base of a tree Orthotrichum diaphanum Schrad. in 

 ' fruit ' was growing sparingly. 



In and by the side of a perennial spring grow Amblystegium 

 filicinum DeNot.; a fine state of Brachythecium rivularc B.cK : S., 

 of brilliant yellow colour; Eurhynchium ruscifor??te Milde, and 

 a small, glossy distant-leaved form of E. Suoartzii Hpbk., with 

 all the leaves squarrose, a moss which some authors would 

 name E. hians or E. distans. On the stones by the side of the 

 lake the writer was pleased to find the rather rare moss 

 Amblystegium irriguum B.&S. in some quantity and apparently 

 well established.'
