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. 3 
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 diffe- 
rences. 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.
