The subspecies macrorhynchus is shown to have both 
a longer wing and a longer bill than andamanensis. The 
heights of the bills provide no differential dimensions ; but 
as regards shape Dr. Stresemann states that the culmen of 
andamanensis has its highest point above the nostril [V.e., 
the profile is arched proximally}: that of macrorhynchus 
is no higher above the nostril than at the base [i.e., the 
profile is straight proximally |. 
Dr. Stresemann goes on to say (pp. 295-6) :—“It is 
very surprising to find that there is a broad space between 
the two areas of distribution of the closely allied forms 
andamanensis and macrorhynchus: this is—strangely 
enough—occupied by a crow of another species, Corvus 
enca compilator ! In all parts of the latter’s range, the 
southern half of the Malay Peninsula, Sumatra, Nias, 
Simalur, Borneo—so far as reliable reports go* there is no 
representative of the coronoides species as we should 
expect ; at least in the southern half of the Malay Peninsula 
and in Sumatra which are parts of the old land bridge 
from India to Java. This is a case of allied, but

‘Finsch indeed records Corvus macrorhynchus from Borneo, 
but probably means compilator. E. S.
