Iris (males) crimson, (females) dark; bill (males) deep 

 fleshy-pink, (females) black ; feet plumbeous. 



Males : T. L. 228, 220, 225, 220, 235 ; W. 134, 130, 129, 

 127, 124.

Very common in south-western Siam, but, though not met 

 with by me in the east or south-east, an example was obtained 

 near Korat in January 1912 by Gyldenstolpe.

^135. Chibia hottentotta (Linn.). 



2 (? , 2 ? . Lat Bua Kao. 



Iris brown ; bill and feet black. 



Males : T. L. 310, 322 ; W. 164, 166 ; B. f. g. 38-5, 39'5. 



Females: T. L. 300, 315; W. 149, 151; B. f. g. 36-5, 

 37-0. 



The males are much more iridescent above and have 

 the beautiful shoulder -hackles longer, while the outer 

 tail-feather is longer and more curled than is the case 

 with the females ; but as these latter have the abdomen 

 and thighs rather greyish it is possible that they are not 

 fully matured.

Differs from both D. a. annectens (Hodgs.) of the Hima- 

 layas and from Malay Peninsula birds, which have been 

 named affinis by Blyth (Journ. Asiat. Soc. Bengal, xi. 

 1842, p. 174), in having the bill very much smaller in all 

 dimensions. Breadth at nostrils 8*7 mm. ; height at chin 

 8*5 or less.
