drawn up wifli a viow to flic mosses of the IJrilisli Islos alone ; " it is therefore 

 precliuled from ailoptiou here. I am compelled, therefore, to adopt the arrangement 

 followed by Mr. William Mitten in his enumeration of "The Mosses of tlu' East 

 Indies," Vol. I. of " The Proceedings of the Linnean Society," Botany, Supplement. 

 If the expression used should appear to imply any idea of regret at the use of this 

 arrangement, that regret has reference solely to my inability to ofler an easier and 

 more familiar ari-angement here, and one more suited to the character of the work. 

 For, however great may be the merits of the arrangement, as an approach to a 

 natural grouping of the species (and Mr. Mitten's great e.xperiencc of this Order of 

 Plants and his acknowledged authority sliould be a sufficient guarantee that they 

 are so), looked at artificially it certainly appears to bo complicated and difficult, 

 BO that I altogether despair of making it intelligible. As, however, my small 

 collection was incoi-porated in this arrangement some years ago b}" Mr. Mitten 

 himself, and as he has now further kindly undertaken to do the same with a cata- 

 logue of mosses coUteted by the late Mr. Kurz, and named by a German Bryologist 

 (which I found impossible to make agree with my own), I can but use his arrange- 

 ment simply as it is and unexplained, or with such slight explanations as are in my 

 power to give ; and this I now accordingly do.
