the whole of the under-surface except the throat ; whereas in mou- 

 hoti a broad median area is generally white. The latter has been 

 obtained by Mr. Williamson at Sriracha and Pak Jong. The Menam 

 River is probably the boundary line between the two forms.

" Iris reddish brown, edge of eyelids yellow ; bare skin of 

 head bluish slate ; bill greenish horn ; feet greenish leaden." 



Total length 341 ; wing 141 ; tail 135 ; tarsus 44; bill from 

 gape 37 mm. 



This form can be separated from G. }'>■ semitorqriata Grant, of 

 Hainan, by larger size and unbroken pectoral band, and from G. p. 

 pectoralis by the buff tips to the tail feathers and the bufFy, not 

 white, edging to the primaries.

Mr. Stuart Baker (Ibis, I.e.) has misunderstood the gist of our 



remarks : we did not condemn his race because it was founded on 



three specimens only, but because those specimens, together with one 



of ours from the same neighbourhood, show no characters which 



cannot be matched in the typical form. Our adult specimen from 



Khao Nawng, which would admittedly belong to E. on. griseiventris 



if that race was valid, can be absolutely matched by specimens from
