Birds of Cameroon Moantain. 509 



Both Dr. Reichenow and Alexander referred the Olive 

 White-eye from Fernando Po to Z. slenoci'icota, but in this 

 they were wrong, as the two forms are perfectly distinct. 

 T have named tlie Fernando Po bird Zosterops stenocricota 

 poensis {vide Bull. B. O. C. xxxv. 1915, p. 54), but it may be 

 as well to give a summary of the differences which dis- 

 tinguish these two closely allied forms. 



Zosterops s. poensis differs from Zosterops stenocricota in 

 its brighter, more golden-yellow and less olive upperparts ; 

 the yellow on the forehead and cheeks is deeper in colour 

 (less canary-yellow) and extends a little further back over the 

 forehead. Lores less distinctly black. Underparts deeper 

 yellow throughout, strongly washed with olive-green, less 

 distinctly on the belly. In Z. stenocricota the belly is pure 

 canary-yellow, only the breast and flanks being washed with 

 olive-green. 



Size (on an average) larger. In a series of twelve birds, 

 the bill (exposed part of culmen) varies from 10-11 mm.; 

 the wing varies from 54-59 mm. 



The measurements of the type-specimen in the British 

 Museum : S ad- Banterbari, Fernando Po, 7. iii, 04, E. 

 Seimund coll., are : — Culmen (exposed portion) 11, wing 58, 

 tail 37, tarsus 165 ram. 



The principal measurements of Zosterops stenocricota, 

 obtained by Alexander, are as follows : — Bill (exposed 

 portion of culmen) 8-9, wing 53-56 mm. 



Dr. Beichenow has recently (Orn. Monatsber. xviii. 1910, 

 p. 192) described two new species of Zosterops from 

 Cameroon, i. e., Zosterops genderuensis^ from the Genderu 

 Mountains, and Zosterops phyllicus, from Kufum in northern 

 Cameroon. I have not been able to examine either of these 

 forms. 



In the same paper Dr. Reichenow describes as new 

 Zosterops strilmpelli, from Kangala (? Kangalua in N.E. 

 Northern Nigeria).
