moist, erect-spreading, about 2 mm. long, .9 broad, not at all or slightly 

 decurrent at base, oblong-lanceolate, acuminate, acute or cuspidate by the 

 short excurrent costa, margins entire, reflexed, narrowly bordered. Costa 

 thin, attenuate, percurrent in the lower leaves, short-excurrent in upper; 

 areolation slightly chlorophyllose, median cells subrectangular or oblong 

 hexagonal, 47-70// long, 16-22 broad. Capsule nodding or inclined, fuscous 

 when old, oblong, tapering into a long neck, curved, dilated at mouth, on a 

 red seta, 1.5-2 cm. long when mature. Operculum conical. Peristome per- 

 fect, teeth of exostome red at base, membrane of endostome broad, cilia 

 appendiculate. 



From Juneau (Canby, 485; Coville and Kearney, 579); Disenchantment 

 Bay (Trelease, 2515). 



This species, which offers many points of resemblance to B. meeseoides 

 Kindb., differs from it by the peristomial teeth which are firmer, stiff er, 

 more scabrous and reddish at the base, the segments more acuminate and 

 perforate from more irregular openings, and the higher membrane. 

 Mnium punctatum anceps Card, and Ther. 



Differs from the typical form in the leaves which are often cuculate and 

 the much smaller upper cells which are almost isodiametric as in Mniu?n 

 glabrescens but distinguished by not having an incrassate border. 



From Unalaska (Trelease, 1727). 

 Bartramiopsis Lescurii Card, and Ther. not Kindb. . 



Dioicous, loosely csespitose, dark-green Stem very slender, filiform, 

 flexuous, simple or forked, loosely foliate. Leafless below for a considerable 

 distance, 2-8 cm. high. Leaves when dry very crispate, when moist arcuate- 

 spreading, 4 mm. long, subsheathing at base, linear-lanceolate acuminate, 

 the basal margins entire below, having 3-5 long cilia above on each side, the 

 margins of the blade plane, strongly serrate, scarcely bordered: costa broad, 

 smooth on back, lamallate on front, 5-8 lamellae, dentate on margins, in 

 cross sections consisting of six to eight rows of cells, cells of the base rect- 

 angular, hyaline, four to six times times longer than broad, areolation of 

 blade opaque, cells minute-hexagonal (8yU in diam. ) bistratose except at mar- 

 gin which is unistratose forming a translucent border. Capsule at first short 

 ovate-cylindrical, when old turbinate, gymnostomous, strongly dilated at 

 mouth, closed by the epiphragm which adheres to the columella. Seta red, 

 short, 8-12 mm. long, operculum high-conical, long-acuminate almost equal- 

 ing the capsule, calyptra without hairs, smooth, short-acuminate, covering 

 the operculum. Spores ovate or subangular 12-16/^. 



From Virgin Bay (Trelease, 1733); Orca (Trelease, 1731); Douglas 

 Island (Trelease, 1729, 1730). 



The moss which was described by Mr. Kindberg, under the name of B . 

 Lescurii^ from sterile specimens collected in Japan, does not seem to be the 

 true Atrichum Lescurii ^s^-m^^, because its leaves are only incurvate and not 

 crispate when dry. On the contrary, it is probable that B, Sitkana of Kind- 

 berg, equally described from sterile specimens, differs in nothing from the 

 species of James. The latter was, after all, imperfectly known until now,
