This slightly larger race of iS. salax was described by 

 Dr. Reichenow from specimens obtained by Dr. Preuss 

 on Cameroon Mt., from 2200-2700 metres. 



It appears to be confined to Cameroon, but is said to 

 have been obtained by Burton in Fertiaudo Po. 



In the Report on the Ruwenzori Collection (Trans. Zool. 

 Soc. six. 1910, p. 376), Mr. W. R. Ogilvie-Grant writing 

 under Pratincola salax Verr. says : — " Prom typical P. salax 

 from Gaboon Dr. Reichenow has separated the bird found 

 at Buea, Cameroon Peak, under the name of P. pallidiffula, 

 disregarding the fact that Captain Shelley's name P. axillaris 

 was given to the bird from the same locality (Cameroon, 

 70C0 ft.) and has many years^ piiority." In a paper ''On 

 Birds from Cameroon " published by Shelley in the Proc. 

 Zool. Soc. 1887, p. 125, he certainly records P. axillaris from 

 Cameroon Mt. (8000 ft.), but this is not the type locality 

 of the species, which was described from Mt. Kilimanjaro 

 (7000 ft.), vide P. Z. S. 1884, p. 556. Reichenow's name 

 P. pallidigula must therefore stand for the Cameroon Chat. 



The immature birds have the feathers of the upperparts 

 tipped with brown and of the throat tipped with black. 



In the series obtained by Alexander the chief difference 

 between it and typical S. salax is in size. 



The wing-measurements of the three adult males from 

 Cameroon Mountain are as follows : 80, 78, 76 mm.; and 

 of the females, 77, 75, 72 mm. 



It is also noticeable that the chestnut breast-band is duller 

 chestnut in colour and somewhat wider in S. s. pallidiyula 

 than in S. s. salax. The width of the chest-patch is always 

 a somewhat variable character in Chats of the same species, 

 but in S. s. pallidiffula the narrowest band is 17 mm. wide, 

 while in ten examples of S. s. salax in the British Museum 

 the widest chest-band measures only 10 mm. In two male 

 examples from the Mauenguba Mountains, which will be
