of trees in the hollows. Ninong is a large town, situated 

 at the north-western base of the Manenguba Mountains. 



A two and a half hours' trek from Ninong brings one 

 to Poala, and an hour's walk from that village to the 

 Manenguba Crater Lakes. Concerning these Alexander 

 writes : — " They are close to one another and are called 

 'Edip' by the natives, i. e. "the two Sisters' — the lai'ger 

 is about a kilometre in diameter, the smaller about 

 half that size and almost emerald-green in colour. Unlike 

 the crater-lake at Kumba, the sides of these are not wooded, 

 but have steep grass-slopes reaching to the water's edge. 

 These two lakes lie at the south-east end of a remarkable 

 natural arena, formed by picturesque grass-hills, 300 to 

 400 feet in height. The centre is flat, covered with long 

 grass, and about two miles in diameter. The lakes lie at an 

 altitude of 6300 feet." 



In the wood near the village of Poala, Alexander met with 

 three or four species hitherto supposed to be confined to 

 Cameroon Mountain or Fernando Po, where he had already 

 procured them. These were Nesocharis shelleyi, Linurgus 

 olivaceus, Cinnyris preussi, and Saxicola salax pallidigula. 



A specially interesting species is the Weaver-Finch, 

 Sitagra anocJilorus, described by Dr. Reichenow from a female 

 obtained at Yakoma on the Welle River. This species is 

 new to the British Museum collection, and the series 

 includes an example of the adult male, hitherto unknown. 



Alexander notes that a well-wooded range of hills about 

 4000 feet in height connects the Manenguba Range with 

 the Cameroon Mountain, commencing about two miles from 

 Ninong and running in a south-westerly direction. This 

 ridge no doubt accounts for the similarity of the highland 

 fauna in the two districts. 



The Manenguba Range, with the birds of which this paper 

 deals, lies some distance from the coast of Cameroon and 

 about 84 miles north-east of Victoria (vide map, Plate VI., 

 July number). 



Having completed his explorations on Cameroon 

 Mountain, Alexander left Buea on the 21st of May, 1909,
