This specimen only differs from a series of C. macro- 

 rhynchus from the Malay Peninsula (wings 303-355 mm.) 

 in having the green sheen of the outer primaries and their 

 coverts and the purple gloss of the rest of the upper-parts 

 much duller. It is possibly nearer the Indian form C. m. 

 levailhmti than typical macrorhynchus., but as I have no 

 material of the former for comparison I have not attempted 

 to place it subspecifically. Stresemann^s recent paper ou 

 Crows is also unavailable at present. 



We found Crows common everywhere in Siam, and it was 

 as much on account of this as of their entertaining manners 

 that I refrained from shooting them, while my collectors 

 carefully ignored them since they are unpleasant to skin 

 because of the lice they swarm with. 



They associate with Vultures in a most intimate manner. 

 I have seen single individuals of each species going about in 

 company and also flocks of both, the Vultures being often 

 both red- and black-necked birds together. One could see 

 Crows and Vultures feeding on the same garbage in a most 

 friendly way, though, if a Vulture fancied a small bit that 

 the Crow was engaged with, the latter bird left it at once ; 

 if they are disturbed all fly away in company or perch 

 mingled together on some neighbouring tree.
