36 APLOPERISTOMI. I Splachnum. 



bordered by 16 distinct, but not equidistant, teeth, for they ap- 

 proach each other in pairs. 



The lid, as Wahlenberg justly observes, is short and obtuse, 

 in which respect Splachnum differs from the Tayloria of Hooker, 

 as published in the Third Number of the Journal of Science and 

 the Arts, and Musci Exotici, (Hookeria, of Schwaegrichen,) as 

 well as in the number and curious configuration of the teeth of 

 the latter. 



The annual species of /Splachnum are usually seen growing on 

 the dung of animals, while the perennial ones are found upon 

 more permanent situations. We have ourselves found Spl. 

 angustatum growing vigorously upon an old stocking on Ingle- 

 borough, Yorkshire ; the same species was seen upon the hat of 

 an unfortunate traveller who had perished on Mount St. Bernard ; 

 and Capt. Parry discovered, during his second Arctic voyage, 

 Splachnum Mnioides growing in the cavity of the nose on the skull 

 of a musk ox. 



* Leaves acuminate. 



1. S. sphcericum ; leaves obovato-rotundate acuminate slightly 

 serrated, apophysis ovato-globose wider than the capsule.

This is the most common species of the genus, and liable to 

 considerable variation in the length of its stems, which are 

 from a quarter of an inch to an inch in height, and of the fruit-
