28 ; Hamilton: Mosses near Lancaster. 
Dr. Braithwaite confirmed my naming of the first gathering, 
viz. as Tinimia norvegica, but remarked upon its small size in 
comparison with the Scoteh plant. On September 23rd 
Dr. Braithwaite wrote: ‘1 did not know until I compare the 
plates of 7. norvegica and Dichodontium flavescens, how very 
close they were in the structure of the leaves, and I now think © 
(after a second examination) the latter must claim the starved 
specimen from Teesdale. A transverse section of the leaf seems 
the only certain means of separating the mosses, as the conical 
papilla in the former are the only absolute distinction.” Again, 
on October 7th, the Doctor wrote: ‘As to the Z7mmza, until 
I compared it with the Dzchodontium, 1 had no idea the two 
mosses were so exactly alike in structure. The balance is in 
favour of its being D. flavescens, though not a respectable sample 
of either genus.’ 
Since writing the above, I have heard that Ceratodon conicus 
has been reported from the East Riding by a Mr. Bailey. I shall 
be glad to have a confirmation of this, if possible, as there seems 
to be some mystery connected with the ‘ find.’
