280a. Microhierax ccsrulescens burmanicus Swann, Burma, 



Syn. List Accip., p. 116 (1920). [Thayet- N. Tenasserim, 



myo, Burma, type in Brit. Mus.] Siam, Ca-mbodia 



White-breasted Pigmy Falcon. S. Annam. 



Wings shorter ; (J 95, ? 104 mm. ; throat 

 vent and thighs only ferruginous, chest 

 and breast silky white, the latter slightly 

 washed with ferruginous ; tail with the 

 subterminal white band in the form of two 

 fair-sized spots of white, much larger than 

 in last form. 



>■ This is quite certainly the correct name for this species. Edwards's plate 

 accurately represents the Indian form except for the white neck band, a point 

 which has given rise to much discussion, but there is no doubt this is an accidental 

 variation, as in the Brit. Mus. coll. such a bird actually e.xists, without a trace of 

 white collar, from Riocour's collection. (B. M. Reg. No. 89, 5, 30, 48) marked 

 " Malaisie," and although not of the Indian race it proves the possibility of the 

 collar being lost. The Indian form, it should be remarked has the under parts 

 white (except vent and thighs) when immature, but yearly uniform ferruginous 

 when adult. The eastern form on the other hand has, when adult, only a small 

 throat patch and the vent and thighs ferruginous, with a wash of same on breast. 

 In a large series a good deal of variation is found in the width and purity of the 

 white collar, and Indian examples in psirticular often show a strong sliading of 

 black on it.
