(366.) E. leiomitra, Kindb. (n. sp.) 



E. rhabdocarpa, Schw. var. leiomilra, Kindb. Ott. Nat. Vol. IV. 61. 



Nearly allied to E. rhabdocarpa but differing in the leaves being 

 shorter, often subspathulate, with the costa vanishing at the apex, 

 peristomial teeth nearly blunt, calyptra not papillose, the spores larger. 



On rocks along the Clearwater River, Athabasca. Lat. 57. July 

 llth, 1888. (J. M. Macoun.) 



(367.) E. Macounii, Aust. ; Lesq. & James, Mosses of N. America, 

 182 ; Canadian Musci, No. 133. 



E. ciliala, Drumm. Muse. Bor.-Am., No. 50. 



On rocks, Canaan Forks, Queen's Co., N.B. (J. Moser.} Crevices 

 of rocks, Tobique River, N.B. (Hay.') On rocks along the Gaspe* 

 coast, Que. ; quite common on rocks at Shannonville, and at Leamy's 

 Lake and Rockcliffe, Ottawa ;. on earth at Pelee Point, Lake Erie ; 

 and in crevices of rocks, Lake Nepigon ; also abundant on rocks at 

 Fort Chipwoyan, Lake Athabasca ; also on rocks at Hector, Rocky 

 Mountains ; on rocks, Deer Park, Lower Arrow Lake ; on rocks at 

 Stewart's Lake Mountain, B.C. ; quite common on damp rocks at 

 Agassiz, Cche Creek and Sicamous, B.C. ; very abundant on rocks at 

 Departure Bay and Victoria, Vancouver Island. (Macoun.} Rocks 

 and banks amongst the Rocky Mountains. (Drummond.) Ounalaska 

 and Kadiak Islands, Behring Sea, 1891. (J. M. Macoun.') Rocky 

 ledges, Mount McKay, near Fort William and Kakabeka Falls, Lake 

 Superior. (Mrs. G. E. Britton.) Greenland. (Ft. Gr.) 



(368.) E. ciliata, Hedw. ; Lesq. & James, Mosses of N. America, 

 182 Canadian Musci, No. 132. 



Encalypta ciliata, Hedw., and E. Macounii, Aust., are very difficult 

 to distinguish apart. The descriptions of the best authors are also not 

 consistent. Schimper in synops. muscor. Europ. p. 343, says : " Peri- 

 stomium eiccitate capsulam horizontaliter claudens, humiditate patens;" 

 Braithwaite, Brit. Moss-flora, p. 283, u peristome when dry horizontally 

 closing the capsule, patent when moist ;" Lesq, & James, Mosses of N. 

 America, p. 182, " peristome spreading when dry ;" Boulay, Muscine'es 

 de la France, p. 314, " dents du peristomo dressdes a l'e*tat sec, inflechies 

 en voute surbaisse'e a l'e*tat humide." It is probable that the authors 

 are confounding both species, also occurring in Europe. E. ciliata 

 is principally found growing in the lower mountain districts. E. 

 Macounii seems to be an alpine species also collected by Kindberg in the 

 NorwegianjJAlps and considered as a new species, E. borealis, Kindb.
