Length of bill: Assam 61, 62. Burma: 97, 58. 
Tenasserim: 58.5, Penang, 60. Andamans: 54-62.5 
(Average of 13 examples : 58.5). Average of 20 examples : 
Re). 
Height of bill: Minimum 20.5, maximum 24.1. 
Average of 22 examples : 22.2. 
Distribution: Assam and Burma, southwards to 
Tenasserim and Penang!; Andamans. The range of the 
form probably extends to the northern part of the Malay 
Peninsula also though no examples seem as yet available. 
All crows which I have seen in Museums from the Malay 
Peninsula and those which I shot in Perak myself were 
Corvus enca compilator Richmond. It is, therefore, not 
clear how one should regard the “ Corvus macrorhynchus ” 
which Robinson and Kloss record in Ibis 1911, p. 71, as 
“very abundant in Trang and also in Langkawi and 
Terutau ” especially as these investigators add the astonish- 
ing remark “From Perak southwards to Johor the Slender- 
billed crow, Corvus enca Horsf., occurs, but is very rare, 
_ only three or four specimens having been obtained” (!). A 
transfer of names between the two species appears to me 
as not improbable.

Corvus limorensis Bonaparte, Compt. Rend, 37, p. 829 (1853—Timor). 
Like C. c. andamanensis and intermedius, but with bill 
of different shape : bill at the base about as high as over 
the nostrils. Base of the teathers in adults always white. 
in young birds brownish white. Iris brown. 
Examples from the Timor group do not appear to 
completely agree with birds from the typical locality : but 
differ in having a shorter bill on the average, clearer white 
bases to the feathers and a rather stronger gloss below ; 
but the Javanese material I have examined?® is insufficient 
for me to decide the question. 
Length of wings : 
Java: 335, 350. Bali: 356. Kangean; 320, 365.
