606 Mr. J. I. S. Whitakcr on 



the plumage of many of these dark-billed birds killed in June 

 is quite as black and glossy as that of the yellow-billed birds 

 killed earlier in the year. 



Besides the variation in the colour of the bill in the present 

 species, the colour of the legs, and also of the irides, would 

 seem to vary considerably according to the season, that of 

 the former being light brown in spring and dark brown in 

 autumn, while the irides are brown in spring and grey in 

 autumn. 



Pyrrhocorax graculus. 



One skin of a male, from Tilula on 21th May. 



Garrulus oenops Whitaker, Bull. B. O. C. vii. p. xviii. 



Adult ^ . Tilula, Great Atlas Mts., Marocco, 24th May, 

 1897. 



Forehead and head plentifully covered with black-tipped 

 feathers, with yellowish-rufous margins, forming a distinct 

 crest, becoming thicker and blacker towards the nape ; hind 

 neck, cheeks, and sides of head rich rufescent vinous colour, 

 extending round and below the throat, which is whitish ; 

 back vinous grey, contrasting greatly with the rufescent nape ; 

 in other respects plumage resembling that of G. glandar'ius, 

 except that the underparts are a trifle darker and more 

 vinous-grey. Bill black ; iris purplish grey ; legs brown. 

 Total length about 12*50 inches, wing 6' 50, culmen 1, 

 tarsus 1'50. 



Of this Jay I have four skins, all males, three being from 

 Tilula, obtained on 24th May, and one obtained at Enzel on 

 30th May. The crest varies a good deal, being much thicker 

 and heavier in two of the specimens than in the other two. 

 The wing-measurements also vary somewhat. This species is 

 apparently closely allied to G. hyrcanus, differing merely in 

 being rather moie rufous on the hind neck and cheeks, and 

 in being a little smaller. 



Pica mauritanica. 



Twelve skins of cJ , ? and young, from Tameshlot, Amsmiz, 

 Frouga, Ecru, and Ras-el-Ain, May and June.
