170 JOURNAL, NATURAL HIST. SOCIETY OF SIAM Vol. I. 
Mr. Hisenhofer’s collection are Hypothymis azuwrea styani, Hartl., 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 Siam. In a later paper I hope to be able 
to solve the question whether this subspecies occurs in Northern Siam 
er not.
