We have recorded the above birds as T. g. annectens since, 

 though ranging a little larger, they do not differ in colour from the 

 type series. On further consideration it appears to us desirable to 

 extend the habitat of the form and to include in it birds from Cen- 

 tral Burma and A.nnam. The range of T. g. pelvica will be, approxi- 

 mately, the Eastern Himalayas, Assam and Manipur (c/. Hume, S. F. 

 xi, p. 93). The more southern birds are smaller and the grey of the 

 head is less restricted (cf. A., p. 205 ; M., p. 205) ; but they are neither 

 so small nor so extensively grey as T. g. fretensis R. & K., from the 

 southern Malay States and N. E. Sumatra. The races may be indi- 

 cated somewhat as follows : 



(i). 2'. g. gularis (Raffles : syn. virgatus Temm.) Size smallest : 

 wing 87-94. The male has a whitish forehead and black tail ; is 

 pure grey above and white below, slightly suffused with vinace- 

 ous on the breast. Java and S. W. Sumatran coast lands 

 (typical locality). 



(ii). T. g.fi-etensis R. «fc K. Size small : wing 97-105. Forehead 

 not white, grey of nape extending over mantle and back, tail 

 blackish brown, underparts largely vinaceous. Sumatra (except 

 the S. W. coastlands), Malay States (type locality) and Patani. 



(iii). T. g. annectens R. & K. Size medium : wing 102-119. Grey 

 of nape less extensive. P. Siam (type locality) to South Aonam 

 and Central Burma. 



(iv). T. g. pelvicus (Hodgs.). Size largest : wing 115-130 or more. 

 Grey strictly confined to crown and nape. Manipur and Assam 

 to Nepal (type locality).
