stood at 293, and the hepatics, or scale -mosses, at 73. The present enumeration 

 brings the former up to 301, and the latter to 84. Almost a moiety of the 

 mosses known to occur in the British Islands, and more than a moiety of the 

 scale-mosses, are still desiderata for our district. That in the future our lists 

 ■will be added to cannot be doubted, especially in the minute and critical species. 

 The publication of Dr. Braithwaite's splendid " British Moss Flora " has been 

 a stimulus to present workers, and its completion cannot fail to stimulate and 

 facilitate future researches. A similar Monograph of British Eepaticoz would 

 be a boon. That tbis interesting group of plants is still imperfectly known to 

 us is largely due to the want of such help. The publishing of additional species 

 is, however, the smaller portion of the labour of the local botanist. A great 

 amount of work has been done, and much remains to be done, in extending our 

 Knowledge of the range and frequency of the plants already on record. 



These lists might have been larger had a laxer method of compilation been 

 adopted. Many notes have been held over where satisfactory specimens were 

 not forthcoming, and doubtless some of these excluded records will prove correct 

 hereafter. As regards the tew notes of Antrim mosses by Mr. Dixon, they 

 stand on the sufficient authority of that gentleman alone. Extracted from the 

 Templeton MSS. we print at the end a number of localities for hepatics not 

 included in the authenticated list. Many of these are believed to be reliable, 

 while some are manifestly incorrect. No specimens are extant wherewith to 

 test these notes, and their confirmation or otherwise remains for the future.
