Mr. Eisenhofer's collection are Hj/poihymis azurea styani, Hart]., or 



one of the other closely allied forms. For such an enquiry large series 



are necessary, and up to the present very little has been done to 



investigate the avifauna of Sian). In a later paper I hope to be able 



to solve the question whether this subspecies occurs in Northern Siam 



or not.
