364 THE MOSSES OF LORD HOWE ISLAND^ 



of Mt. Gower, and I have no doubt that others will yet be dis- 

 covered. Very interesting, also, is the eastern side of Mt Lidg- 

 bird, where the land slopes up from the ocean to enormous cliffs 

 that bar access, on that side at any rate, to the top of the 

 mountain. The centre and north of the island, while less inter- 

 esting bryologically than the southern end, are by no means 

 negligible; and the neighbourhood of the northern "Look-Out," 

 the Northern Hills, and the North Head, supplied me with 

 many treasures. 



Specimens of nearly all my packets of mosses were submitted 

 to Dr. V. F. Brotherus, and he kindly found time to examine 

 them and report upon them. The results of our joint work 

 appear in the following pages. Twenty-two new species are de- 

 scribed, and a few new varieties. 



Some supplementary notes, dealing mainly with previous 

 records, will be found at the end. 



I take this opportunity of sincerely thanking Dr. Brotherus 

 for his invaluable assistance, without which the publication of 

 this paper would have been scarcely possible.

Trematodon sp. (sporogon destroyed). 



Second open gully, south of King's, at western base of Mt. 



Lidgbiixl. 



The specimens were indeterminable, on account of the capsules 

 being too old; plants should be collected in April or May, or in 

 October or November.
