Dear: Professor. Collins: 
I am very much obliged for: the speoimens 
of hepatios from.Maine,< Rhode Island and Canada. 
I. have determined all except a very. few and en¬ 
close a list by number. I. was glad to see the 
Riccardia palmat.a from Maine. It had been re¬ 
ported^ from there but I had not seen speoimens. 
The two numbers of Lophozia inflata are a little 
doubtful because sterile plants of this species 
simulate Cephalozia fluitans in a.marked degree. 
I have referred them to L. inflata on account of 
their, rather small leaf-cells,., those in the Geph¬ 
alozia being considerably larger. ‘The Gymno- 
mitrium is also interesting; • Macoun does not list 
it from Quebec, although it is common enough on 
the. high mountains, of New England. 
Very, sincerely yours,
