Twenty-six examples of coronoides against six of enca 
(vide postea) from the same area ! 
The birds of the Malay Peninsula have both the larger 
wing and longer bill ranges of macrorhynchus and must, 
I think, be placed under that name, for as regards the forms 
of the bill the differences stated by Dr. Stresemann do not 
seem to hold: I find both shapes in the Malayan series 
and of the three Javan birds one has the bill higher at the 
nostrils than at the base, while in the other two, the height 
at both places is the same. 
My conclusions are therefore that a form of the species 
Corvus coronoides occurs throughout the whole of the 
Malay Peninsula where it is much commoner than the 
species Corvus enca; and that south of Tenasserim (say 
Lat. 11° N.) it is Corvus coronoides macrorhynchus Wagl. 
CORVUS ENCA. 
Six specimens haye been obtained during the same 
period and in the same area as the 26 examples of 
C. coronoides recorded above : the apparant occurrence is 
therefore, only one to four, The details are :—
