and we confess our readiness to subscribe to the opinion of 

 those who may be disposed to consider them all the same 

 species. 



11. CINCLIDOTUS. 



GEN. CHAR. Frwtstalks terminal ; Peristome single, of 

 32 filiform, twisted teeth, anastomosing at their 

 base; Calyptra mitriform. (TAB. I.) 



The calyptrse of all the specimens we have examined are so far 

 split on one side as to leave some doubt as to the propriety of our 

 calling them mitriform, which we do in deference to preceding 

 botanists. We cannot hesitate, however, to confess that in the 

 present instance we have no great reliance on the character taken 

 from the calyptra, which among other tribes of mosses we have 

 found to be of the greatest importance. The fruit we believe to 

 be terminal, although in the majority of instances situated on 

 branches so short as scarcely to leave room for more than peri- 

 chaetial leaves. The general appearance of the single known spe- 

 .cies of this genus is that of a Trichostomum, whilst the peristome 

 approaches nearer to that of Tortula.

HAB. Growing on stones and wood in streams of water. 



Plant from four to six inches long, branched, of a dark 

 lurid green colour. Leaves imbricating the stem on every 

 fiide, elliptico-laneeolate, acuminated, margined, entire, 

 flexuose, curled when dry, nerve strong. Perichaetial leaves 

 nearly as long as the fruit, much acuminated. Fruitstalks 

 shorter than the capsule. Capsules oblong, smooth, brown. 

 Lid conico-acuminated. Peristome bright red, rigid, arising 

 from the reticulated membrane ; teeth numerous, capillary, 

 slightly twisted, below anastomosing.
