SOME NEW MOSSES FROM THE PRIBYLOV ISLANDS, 



BEHRINCx SE,\. 



(Jas. M. Macoun.) 



While with the British Behring Sea Commission last summer a 

 numbc^r ot plants were collected among which were several mosses new 

 to America and a few new to science. 



Dr. N. C- Kindberg has already described six new species and 

 varieties which are given below. All were found on St. Paul Island, in 

 about 57° N. Lat. and 170° W. Long. 



Ceuatodon heterophyllus, Kindb. n. sp. Agrees with Cent- 

 todon puipurens in the shape of the ca[)sule and the stem leaves, the 

 not excurrent costa and the revolvable annulus, but the capsule is often 

 more curved and distinctly strumose ; agrees with Ceralodon conicus 

 (Hampe.) in the peristomial teeth having few articulations; differs from 

 both in the blunt perichetial leaves, is also very peculiar in the short, 

 concave, sub-oval leaves ot the long shoots. 



DiDVMODON B.\OEN-PowELLi, Kindb. n. sp. Differs from Didymo- 

 dofi rube/lus in the dioecious inflorescence, the blunt, conic, very short 

 lid, scarcely \ of the capsule, and the distinctly dentate leaves (as in 

 Didymodoti alpigenm, Vent.) The tufts are compact, about 2 cm. high, 

 the leaves revolute nearly all around, short-acuminate, the lower pale 

 brown, perichetial ones longer acuminate or subulate entire. The 

 capsules are (unripe) more or less curved, the pedicel pale red. Named 

 for Sir George Baden Powell, one of the commissioners. 



Webera canaliculata, C. M.& Kindb., var. microcarpa, Kindb. 

 n. var. Differs only in the much smaller capsule. 



Bryum br.'VCHYNeuron, Kindb., n. sp. Agrees with Bryum 

 pendulum in the synoecious inflorescence, the peristomes orange, the
