140 GEOLOGICAL AND NATURAL HISTORY SURVEY OF CANADA. 



(539.) M. orthorrhynchum, Bruch & Schimp. ; Lesq. & James, 

 Mosses of N. America. 246 ; Canadian Musci, No. 479, in part. 



Grand Falls of the ISTipisiquit, KB. (Fowler's Cat.) Canaan Forks 

 and Tay, N.B. (J. Moser.) Pirate's Cove, Straits of Canso, KS. ; Ste. 

 Anne des Monts Eiver, Graspe* Co., Que. ; on rocks in McKay's woods 

 at Ottawa ; in mud upon rocks at Owen Sound, Ont. ; dry rocks at 

 Lake JSTepigon ; crevices of rocks, three miles below Hector, Eocky 

 Mountains ; on rocks in Eoger's Pass, Selkirk Mountains ; on rocks, 

 Cache Creek, and Agassiz, B.C. (Macoun.) Crevices of rocks, Mount 

 Queest, Gold Eange, B.C. (J. M. Macoun.) Greenland. (Fl. G-r.) 



(540.) M. decurrens, C. M. & Kindb. (n. sp.) ; Canadian Musci, 

 No. 517. 



Dioecious. Loosely tufted. Stem very loosely foliate, naked 

 below, elongate. Leaves green or finally reddish, subdistichous, long- 

 decurrent, often red at the margins and the wings, doubly dentate, 

 lanceolate, the inner perichetial ones sublinear, red-cuspidate ; cells 

 smaller than in Minium umbratile ; costa sub-percurrent, often red, in 

 the inner perichetial leaves excurrent. Capsule single, oval, inclined ; 

 lid pale, conic, not margined, short-apiculate, not rostrate, teeth dark 

 yellow ; pedicel reddish. 



This species resembles Mnium orthorrhynchum in the size of the 

 capsule ; the leaf cells are not much larger ; from Mnium umbratile 

 it is well distinct, also in the narrower leaves less twisted when dry. 



On stones in a mountain brook entering the Columbia about a mile 

 above Eevelstoke, on the east side, May 4th, 1 890 ; also at Pass Creek 

 Falls, near Sproat, Columbia Eiver, B.C. (Macoun.} 



(541.) M. pseudo-lycopodioides, C. M. & Kindb. 



M. lycopodioides, Lesq. & James, Mosses of N. America, 246 ; Canadian 



Musci, No. 197. 

 M. orthorrhynchum, Canadian Musci, No. 471, in part. 



This species is already described by Lesq. & James, but is a new 

 species quite distinct and not corresponding to the true M. lycopodioides, 

 Schw. (fide C. Muell.) From the closely allied M. orthorrhynchum it is 

 separated by the excurrent costa of the upper leaves and the narrower 

 capsule. Fortune Bay and Placentia Bay, Newfoundland. (Rev. A. 

 Waghorne. In a damp shaded ravine, Bass Eiver ; also at Fredericton, 

 KB. (Fowler's Gat.) Eocky banks, Tobique Eiver, N.B. (Hay.}
