2 LETTER FROM LIEUT. R. C. BEAVAN. [Jan. 9, 



had obtained specimens of both of these Lemurs, and determined 

 them as male and female of the same species*. 



A letter was read from Sir C. W. Dilke, Bart., F.Z.S., announcing 

 the occurrence of a specimen of the Gyr Falcon (Falco gyrfalco) in 

 the Holt forest near Famham. 



Mr. P. L. Sclater read an extract from a letter addressed to him 

 by Dr. H. Burmeister, For. Memb., concerning the Tyrannidce found 

 in the vicinity of Buenos Ayres. These were stated to be 



Saurophagus sulphuratus (common), 

 Tyrannus violentus (common). 



aurantio-atro-cristatus (rare). 



Bathmidurus variegatus (rare). 

 Elainea modest a (rare). 

 Muscipeta virgata (rare). 

 Pyrocephalus coronatus (common). 

 Serpophaga nigricans (rare). 



subcristata (common). 



Euscarthmus {Hapalocercus) flaviventris (rare). 



Dr. Burmeister's list was accompanied by drawings and descrip- 

 tions of two other species of this group, which Mr. Sclater had not 

 been able to determine. 



The following extracts were read from a letter addressed to the 

 Secretary by Lieut. R. C. Beavau, Corr. Memb., dated Moulmein, 

 October 23rd, 1865 :— 



" I have just returned from a trip to Zwagaben (a remarkable lime- 

 stone rock about twenty-five miles to the north of this, elevation about 

 2000 feet, and about the only limestone rock in the vicinity which 

 can be climbed) with the Rev. C. G. Parish, the chaplain here, who 

 is well known as a botanist. A day and a half up the Salween by 

 boat at this time of the year brings one to the small village of Kor- 

 like ; and from this point to the foot of the rock is only four or five 

 miles, through a swamp which has to be traversed on elephant-back. 

 At the foot of Zwagaben we were lucky enough to find a small water- 

 tight zyat or resting-house, well shingled and boarded, no small boon 

 in this land of rain ; and this we made our headquarters. The pull 

 up the mountain was very stiff: in places one has to scramble up on 

 all fours ; and here and there we came across good teak ladders placed 

 for the accommodation of pilgrims to the pagoda at the top. Both 

 these and the rest-house at the bottom have been erected by some 

 pious Burman or other, with the hope of reward hereafter. 



" About a quarter of the way up there is a small village, three or 

 four huts only, and a poongye (priest) house, where we were glad 

 enough to halt and get a drink of water.
