The Scottish Naturalist. 



Hab. On rocks near Callander, in July, 1865. 



The stems of this moss are often an inch in length. The leaves 

 are in shape not unlike those of Gr. crinita, though a little longer, 

 as well as narrower at apex. 



This moss also bears a striking resemblance to Coscinodon crib- 

 rosus, or rather to an enlarged and coarse condition of that species ; 

 but in the absence of calyptra and lid I cannot venture to include 

 it in this genus, more especially as I cannot perceive sulci at the 

 bases of the leaves. The areolation is alike in the two.
