* Hymenostomum microslomum ranges from Massachusetts to the base of the Rooky Mountains. It was collected by 

 Drummoud, and also by Mr. B. Hall, in a recent tour of botanical exploration with Dr. Parry, 1862. 



t The very rare and beautiful Campyloslelium saxicola Bryol. Eur. was discovered this year by Mr. R. C. Ingraham, of 

 New Bedford, Mass., on boulders of granite. 



| 1 could add three apparently new species of this genus, brought from the Rocky Mountains by Mr. B. Hall ; but all 

 these species are without fruit, and an exact determination of them is of course impossible. 



2 Dcsmatodon flav Leans ranges westward from the Rocky Mountains. 



Ii I'oUia subsessilis ranges westward from Illinois. (E. Hall.) 



11 Zygodon, Sullivantii Miill. It has never been found in fruit, and is thus a species of doubtful affinity. 



** The species of this genus, and also of Macromitrium and Syrrhopodon are tropical. Each of them has still one repre- 

 sentative in Eastern North America.
