C. guttacristatm indomalayicus, Southern Siam and 

 North Malay Peninsula, Wing 156 mm. (mean of twelve. ) 



C. gnttacristatus delessertii, Southern India. Wing 

 averaging 152. 



C. guttacristatus {unnamed). 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 190 to 143 or a 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 subspeciiically 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. 



" Iris dark hazel, orbits -date, tall greenish horn, culmen 

 at base darker feet slate.'"
