The adult females from the Langbiaii Peaks are also very 

 uniform, the only difference being in the tail, which varies 

 considerably in the amount of vermiculation; this is almost 

 absent in some specimens. In the bird from Dalat, however, 

 the vermicnlations are very much coarser and there are also 

 oblique huffy black-edged bars. The inner primaries and 

 secondaries are also somewhat coarsely vermiculated with 

 narrow ochreous-buffy bars, black-edged towards their tips; 

 and the upper surface ge^ierally is extremely finely vermi- 

 culated. Failing further evidence we are, however, unable 

 to accept this bird as representing another form. 



A half-grown female from the Langbian Peaks resembles 

 the adults, but has the remains of a younger plumage, of 

 which the feathers of the back are more rufescent, clearly 

 and boldly barred with black and with pale buff tips. 

 Beneath, the centre of the belly is more greyish than in the 

 adults. The throat is dull white and there are two distinct 

 rounded dirty Avhite malar patches. 



The chick in down is pale lemon-yellow beneath ; head 

 rufous buff; mantle black with rufous tips; thighs rufous 

 externally, lemon-white internally. 



Three species of this genus have been described from 

 Annam, viz., the present form, Gennceus beli *, from the 

 neighbourhood of Hue,, which, as Stuart Baker points out, 

 is very close indeed to the present form, and Gennceus 

 edwardsif, h'om Kuang-Tri, slightly farther to the north. 

 The fij,ure of this species [Nouv. Arch, du Museum, 

 4th series, Memoires, vol. i. pi. 10], which seems to have 

 escaped Stuart Baker's notice, shows that it belongs to a 

 totally distinct section of the genus, and that there can be 

 no question of its identity witii either of the otlier forms.
