 The throat is bare to a rather great extent. The spe- 

 cimens do not seem to differ from european Rooks in colour 

 or measurements. The outer tailfeathers are rather short 

 about 3 cm. short er than the median ones.

Wing 250, tail 133, tarsus 42, culmen 33 mm. 



This Daw is a very dark bird . The coUar round the hind 

 neck from ear to ear dark grey, otherwise it is above and 

 below uniformly blackish, only a little more greyish on the 

 belly. The feathers of the wings are much weatherworn and 

 therefore somewhat brownish. The specimen does not agree 

 with the description of any race of Coloeus in Hartert's ma- 

 nual^. It might be an individual aberration and no defini- 

 tive statement can be based on a single specimen.

 When compared with swedish specimens these are appa- 

 rently darker on the upper parts and in two of them which 

 appear to be old the white spöts on the back measuring as 

 a rule about 1 cm. in length, are decidedly longer than in 

 the swedish specimens which I ha ve had for comparison. The 

 black quills ha ve also a stronger metalHc lustre than in swe- 

 dish specimens. The ground colour of the lower parts is also 

 darker than in swedish specimens, but the spöts which are 

 more purely white seem to be less numerous on the belly. 

 The feathers of the chin on the contrary have much more 

 white than in swedish specimens. The greater and median
