A female spccimen, collected at the neighbourhood of Koh Lak in the Siamese 

 Malaya, appears to belong to this race. Unfortunatcly I ha ve only been able to compare 

 my specimen with some other specimens from Java in the collections of the Royal Natural 

 History Museum in Stockholm, but these specimens, which according to locality ought 

 to belong to this race, are absolutely identical as to size and colouration with my own 

 specimen.

In my former paper on the Birds of Siarn (Kungl. Svenska Vetenskapsakademiens 

 Handlingar, Band 50. N:o 8 p. 37) I have referred the species of the Black-naped Blue 

 Flycatcher inhabiting Northern Siarn to H. a. prophata Oberh. 



During my last journey I collected a large series of this beautiful Flycatcher at 

 different parts of Northern Siarn. 



Stresemann has recently (Nov. Zool., Vol. 20 1913 p. 293 — 297) given a review 

 of the forms of Hypothymis azurea, Bodd. based on a very large material. 



He considers H. a. styani Hartl. as to inhabit Siarn and the adjoining countries
