black ; sides of face and car-coverts black, washed with blue ; 

 under surface of body bright orange-rufous, creamy buff in 

 the middle of the abdomen ; thighs blue-black on the outer 

 aspect, orange buff on the inner ; under wing-coverts orange ;

 to the inner webs. Total length 5'7 inches, culmen 0"55, 

 wing 2"9, tail 2*35, tarsus 0'6. 



Adult female. Different from the male. General colour 

 above tawny brown, duller on the liead, inclining to foxy 

 chestnut on the upper tail-coverts ; the tail chestnut-red ; 

 wing-coverts dull brown, edged with tawny brown, so that 

 they appear like the back ; the greater coverts and the quills 

 more narrowly edged ; the innermost secondaries light fulvous 

 brown, edged with tawny, with indistinct cross lines of dark 

 brown ; forehead, eyebrow, and a ring round the eye tawny ; 

 in front of the eye a triangular patch of dull fulvous ; sides 

 of face dull ashy brown, with a faint wash of fulvous ; cheeks 

 and under surface of body orange-buff, richer on the breast ; 

 the lower abdomen fulvescent white ; under wing-coverts pale 

 orange-buff. Total length 5*9 inches, culmen 0'55, wing 2*7, 

 tail 2'25, tarsus 0*55. 



Young male. Like the old female, but darker, and with 

 light buff shaft-lines, the lower back with a bluish shade, the 

 upper tail-coverts bright smalt-blue ; the tail dull blue, in- 

 stead of chestnut ; wing-coverts and secondaries tipped with 

 orange-buff; forehead, eyebrow, and sides of face deep orange- 

 buff ; under surface of body more richly coloured than in the 

 female, the breast being bright orange as well as the flanks.

 transitional grades ; and the first of these is when his prin- 

 cipal differences are his blue tail, bright orange breast, and 

 orange-tipped wing-coverts ; otherwise he greatly resembles 

 the female. It is unfortunate that the species must bear the 

 name of rufifrons, as, when adult, the forehead is brilliant 

 blue, and the type of C. rufifrons in the British Museum 

 shows that the species is founded on a male which has gained 

 almost perfect plumage but still retains the rufous eyelid and
