In 1910 Hartert (Nov. Zool. xvii. p. 225) recorded his 

 opinion that H. a. stijani was the same as //. a. cceruleo- 

 cephala (Sykes) from the Dekkan, and a year later Ober- 

 holser in his "Monograph of the Flycatcher Genera 

 Hijpothymis and Cyanonympha" (Proc. U.S. Nat. Mus. 

 xxxix. p. 596) with inadequate material in front of him 

 was content to accept this pronouncement, and the range of 

 coiruleocephala was thus defined as all Peninsular India and 

 Indo-China — a very improbable distribution considering- the 

 subspecific differentiation that occurs elsewhere. In 1913, 

 however, Stresemann, in his revision of the species, came 

 to the conclusion that H. a. cceruleocephala was confined 

 to Peninsular India (Dekkan and southwards), and that 

 H. a. styani was a good subspecies which extended from 

 Hainan through Indo-China to India north of the Dekkan. 

 Stresemann had five series of specimens from these areas, 

 and the recognition of two races — an Indian and an Indo- 

 Chinese — was to be expected. 



1 have no hesitation in recording my white-bellied 

 examples as H. a. styani ; a comparison of them with 

 Malayan birds shows that the change to H. a. prophata 

 Oberholser takes place somewhere in Peninsular Siam.
