VUSCI. 



other mosses, and especially of the falcate section of Hyp- 

 num. With Stipulae they have nothing in common, for inde- 

 pendently of their being single organs, — even when they may 

 be considered referable to, or as belonging to the lateral leaves, 

 it is only to one series of these, and only to one point of these 

 (the lower point of insertion), that they correspond. 



I do not know whether the nature of the compound hairs 

 existing on the vaginula or calyptrre of many mosses has been 

 hinted at. In Neckera crinita they are obviously reduced 

 perichaetial leaves. Such is probably their nature in all cases. 

 They are not to be confounded with the simple hairs existing 

 in similar situations, such being referable to Paraphyses. 



Anhymenium I have ventured to propose as a new genus, 

 remarkable for the proportionally very small teeth of the 

 outer peristome, and for the great development of the pro- 

 cesses of the inner peristome, considered relatively to the al- 

 most total absence of a basilar membrane. In this instance, 

 the disparity between the membrane and the processes, in 

 favour of the latter, is greater even than in Climacium. 



Pleuropus, the seconed genus, which appears to me new, 

 has the same relation to Leskia, etc. that Brachymenium has 

 to Bryum. From the former genus it is alone distinguishable 

 by the laterality of its setae, and the accompanying difference 

 in habit. 



Almost the whole of the above descriptions were made from 

 dried specimens. I trust that considerable indulgence will be 

 shewn to the numerous errors that must exist, especially as re- 

 gards the fabrication of new species. Advice in Muscology is 

 not to be obtained in India; and by means of consultation are 

 limited to Bridel's Bryologia Universalis, the Musci Exotici of 

 Dr. Hooker, and the Muscologia Brittannica of Dr. Hooker and 

 Taylor. In means of comparison with authentically named spe- 

 cimens, I am altogether deficient : owing to this, I have not 

 ventured to meddle with either Leskia or Hypnum, under any 

 circumstances, a business of some difficulty, but one to me al- 

 most insuperable, on account of the unnatural arrangement of 

 Hypnum by Bridel.
