Andreaea alpestris (Thed.) Schimp. Sheep Camp, Dyea 

 Creek. This has leaves very similar to the preceding in size 

 and shape, but the leaf cells below are longer, thinner-walled 

 and less pitted. It should, perhaps, be regarded as only a 

 variety of -pctrophila, as Braithwait does (512). 



Gymnostomum curvir ostrum (Ehrh.) Iledw. Yukon 

 River bluff just below Dawson (524). 



Dicranozveisia crispula (Iledw.) Lindb. Common on 

 rocks about Lake Lindeman (555). 



Dicranozveisia coutermina R. & C. Locality of preceding 



(556). 



Cynodontium Sckisti (Wahlb.) Lindb. On earth about 

 ledges of rock. The leaves are roughly papillose on both 

 faces. Upper leaf-cells irregular, not much elongated, up to 

 about .008 mm. long. Rough spores up to .016 mm. Teeth 

 either solid or with two or three perforations above (525). 



Cynodontium torqucscens (Bruch) Limpr. Lake Linde- 

 man, on thin earth over rock. Dawson, on rock. Leaves 

 papillose, up to 3 mm. long, twice longer and much narrower- 

 pointed than in alpestris. Inner perichaetial leaves longer- 

 pointed and less clasping than in gracilesccns, foliage leaves 

 also narrower above. The perigonium, of two leaves, close 

 under the perichaetium or almost at its side (526). 



Cynodontium poly carpum (Ehrh.) Schimp. Common on 

 rock on upper Dyea cr., also just over the Coast Range on 

 streams flowing into Lake Lindeman. The leaves are dis- 

 tinctly serrate above (527). 



Cynodontium strumiferum (Ehrh.) DeNot. Lake Linde- 

 man. In crevices of rock (528). 



Ourop/iorus virens (Sw.) Brid. {Cynodontium virens 

 Schimp.) About springs between Lakes Lindeman and 

 Bennett. Alar cells sometimes more or less enlarged or in-
