Length of bill : Assam 61, 62. Burma : 57, 58. 

 '1 enasserim : 58.5, Penang, 60. Aiidamans : 54-62.5 

 (Average of 13 examples : 58.5) . Average of 20 examples : 

 58.9. 



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. 

 iVll crows which I have seen in Museums from the Malay 

 Peninsula and those which I shot in Perak myself were 

 Corims 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- 

 Ijilled 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.

Like C r. andamanensis and intermedius, but with biU 

 of different shape : bill at the base about as high as over 

 the nostrils. Base of the feathers in adults always white, 

 in young birds brownish wiiite. 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 featliers and a rather stronger gloss below , 

 but the Javanese material 1 have examined^ is insuilicienl 

 for me to decide the question.
