C. guttacristatus indomalayicus, Southern Siam and 
North Malay Peninsula, Wing 156 mm. (mean of twelve.) 
C. guttacristatus delessertit, Southern India. Wing 
averaging 152. 
C. guttacristatus (uunamed). Extreme south Malay 
Peninsula, Wing, 145 mm. 
The bills grade in even greater ratio. 
The maximum range of wing of the species as a whole is 
from about 1g0 to 143 ora subspecies to every nine mm. as 
all authorities seem agreed that no constant differences in 
colouration can be detected except possibly as noted above, a 
slightly more intense tint in the Indo-Chinese and Indo- 
Malayan specimens.

I have no access to Hesse’s description of this form 
described from Burmah but which is apparently merely a 
larger form of the Malayan race, nor have I specimens from 
Java whence came Temminck’s type so these specimens cannot 
at present be identified subspecifically with any certainty. 
The wings of the males are 222, 228, 228 and of the four 
females, 221, 227, 227, 235, while Glydenstolpe’s two males 
from North Siam which would certainly belong to Hesse’s 
race are given as 242, 235. A female from Kuala Lipis, 
Pahang is 229 mm. 
Compared with a female from Anyut Paku, Seribas, S. W. 
Sarawak, whose wing measures 230 mm. all the Malayan birds 
are much greyer and less slaty black, especially on the top of 
the head, the mantle and undersurface, but this difference may 
be merely individual. 
“Tris dark. hazel, orbits slate, tall greenish horn, culmen 
at base darker feet slate.”’
