follows : — Bastard-wing, outer primary-coverts and first to 

 fourth primaries (old) brown edged witli rufous ; fifth in quill, 

 sixth two-thirds grown, seventh to tenth (new) black edged 

 with white ; first secondary (new) black edged with white, 

 second in quill, third to sixth (old) brown edged with rufous, 

 seventh to eighth (new) white with black shafts ; greater 

 coverts (new) the same; median coverts (old, but many 

 missing) rufous ; lesser coverts white (new) and rufous (old) ; 

 tail, three outer pairs rufous (old), three middle pairs 

 (growing) white with black shafts and edges ; entire head 

 in quill ; upper- and underparts partially rufous (old) and 

 partially white (new). The old feathers were like those of 

 a first-winter bird, being less chestnut than in the adult 

 red form and not so yellowish as in the juvenile, while the 

 old feathers of the upper breast were not metallic as in 

 the adult. 



From the above evidence Mr. Witherby concluded that 

 the bird was passing in one moult from the short-tailed 

 rufous first-winter stage into the fully white phase — from 

 which it might be argued that the attainment of the fully 

 white phase was not necessarily a question of years. 



Colonel Stephexson Clarke exhibited and described an 

 example of a new Creeper from Northern Nigeria, which he 

 proposed to name 



Salpornis salvadorii occidentals, subsp. n. 



Adult. Differs from all the known forms of the genus 

 Salpornis in having the underparts white, with a rather 

 narrow bar across the middle of each feather of the breast 

 and belly, and sometimes a concealed second bar across the 

 basal portion. In S. salvadorii and its close allies &. s. 

 emmi and 8. s. abyssinica, the feathers of the underparts are 

 pale rufous-buff or rufous, with a white terminal spot and a 

 black subterminal band. The upper parts are dark brown, 

 with the head streaked and the back spotted with pure white. 

 Culmen 20 mm. ; wing 90; tail 49 ; tarsus 16. 



Hab. North Nigeria.
