 Nortli America, 271. 



The following list of mosses has been reported from Vermont by Frost 

 bnt no specimens of these species have been found either in his herbarium 

 at Brattleboro or in the Gray (Sullivant) Herbarium, wliich Dr. Robinson 

 has very kindly searched for me: 



Bruchia flexuosa Muell. 



Fissidens minutulus SuUiv. 



Leptotrichum vaginans Lesq. & James. 



Grimmia Pennsylvanica Schwaegr. 



Atrichum crispum James. 



Dichelyma capillacea Br. & Sch. 



Pterigynandrum filiforme Hedw. 



Hypnum (Thuidium) gracile Br. & Sch. 



Hypnum (Thuidium) minutulum Hedw. 



Hypnum demissum, Wils. 



Hypnum ( Plagiothecium ) Sullivantiae Schimp. 



Many of these undoubtedly occur in the State and will be found again 

 sooner or later. 



Bryum pseudotriquetrum was also reported by Frost and in the Gray 

 Herbarium is a specimen labelled "Bryum pseudotriquetrum? Brattle- 

 boro, Frost." On examination of this specimen it seemed very doubtfully 

 this species and consequently it is not included in the list. 



APPBINDIX. 



The author greatl}- regrets that he did not sooner know of the great 

 ^amount of work done on Vermont mosses by Dr. George G. Kennedy of 

 Readville, Mass. It has been possible to introduce into the text most of 

 his additions but a large number of localities which should have been cred- 

 ited to him came too late to be inserted.

Mrs. Britton informs us that Dr. Frost's Physcomitrium pyriforme is 

 in all probability P. turbinatum (Mx.) Brid.
