198 BIRDS OF THE 



tinge on the crown, and the blue color is reduced to the 

 upper tail-coverts and the outer webs of the tail-feathers; 

 moreover the lores (and in some specimens also a ring 

 round the eyes) are rufous instead of pure white. In younger 

 females the blue color on upper tail-coverts and tail are 

 entirely wanting. The young male does not pass through 

 the color of the female as is clearly shown by our above 

 mentioned nestling, which, though spotted with rufous all 

 over the upper surface, has the very short quills and upper 

 wing-coverts already edged with the blue color of the 

 adult bird. The entire lower surface of this nestling is 

 orange rufous with a narrow black margin to some of the 

 feathers, but no trace of a black chin-spot can be seen. 

 The feet in the dried skin of this nestling are whitish 

 yellow, like in the type of the species in our Museum, 

 which is, by the way, not a fully adult bird, as it has 

 some rusty red spots to the tips of the greater wing- 

 coverts. 



I may not neglect here to say that my series of males 

 from the Liang Koeboeng does not absolutely agree with 

 the type, this latter showing a slightly more purplish tinge 

 on the upper surface, and a more distinct cobalt color on 

 the rump, while the numerous black feathers on the chin 

 indicate a larger black chin-spot than in any of my spe- 

 cimens from the Liang Koeboeng-range. The type being, 

 however, not fully adult (having a few rusty tips to the 

 wing-coverts) and in worn plumage, I dare not keep 

 them separate on account of the above mentioned difie- 

 reuces. Unfortunately I cannot dispose of any specimen 

 of the so-called S. rufifrons from other localities of Borneo 

 and therefore I am unable to tell whether this latter 

 form agrees more with the typical specimen of our S. 

 coeruleata or with my specimens from Liang Koeboeng.
