THE IRISH JAY. 235 



in the British Jay. The most striking differences are 

 in the dark rufous colouring of the sides of the head, ear- 

 coverts and underparts and the darker " crest." 



The measurements of the examples are :— Wing, 

 171-186 mm. ; bill (from nostril to tip), 18-21.5 mm. 

 The measurements are perhaps slightly smaller on the 

 average than those of G. g. rufitergum. 



We have therefore no hesitation in separating this 

 bird under the name of 



GARRULU.S GLAND ARIUS HIBERNICUS. 



Type : <$ ad., Co. Wexford, November, 1910, in the 

 Tring Museum. Cotype : 9 ad., Birr, King's Co., 

 IS.xii. 1910, in H. F. Witherby's coll. 



Although all the specimens we have examined are 

 easily separable from examples of the British Jay, some 

 are darker than others, one specimen from Co. Waterford 

 in the Dublin Museum being remarkably dark, while in 

 some specimens in Witherby's collection the blue on the 

 feathers of the crown is very conspicuous. Of fifty British 

 Jays in the Tring Museum, only one, a male, shot near 

 Tring, November 21st, 1902, by the Hon. Walter 

 Rothschild, approaches G. g. hibernicns, but even this is 

 paler than the latter, above and below, and especially 

 in the head. The Irish Jay has a very restricted range, 

 and is only found in parts of the province of Leinster 

 and the adjoining part of Munster {Birds of Ireland) and 

 has recently spread into South Ulster (Brit. Birds, 

 Vol. III., p. 341). 



Three Irish birds have now been found to be distinct 

 from their British representatives — Hartert has already 

 referred in these pages to the Irish Dipper {supra, p. 136), 

 while at the December meeting of the British Orni- 

 thologists' Club Mr. W. R. Ogilvie-Grant described the 

 Irish Coal-Titmouse as distinct.
