Eggs. These have not yet been recorded fi'om Celebes. Fi-om Java, Bernstein (J. f. 0. 

 1859, 277) describes them as 4 in number, greenish blue with ohve-brown and grey 

 spots and points, mostly small, large and numei-ous only at the lai'ge end, but never 

 so large and numerous as in C. macrorhyneJms. Eesembling those of the Book, 

 occasionally those of the Jackdaw. Size 34 — -40 X 27 — 29 mm. 



Nest. In the top of a liigh, thick-leaved tree; made of dry twigs, roots and coarse stalks; 

 lined, like that of C. macrm'hynchu.'i, with stalks, small roots, elastic fibres of the 

 Areng palm (Bernstein 1. c). 



Distribution. Celebes and Sula: — Lembeh, Banka, Mantehage and Manado tua (Nat. Coll.), 

 Talissi Id. fHickson 13), Minahassa (Rosenb. 1, Wallace c 1, etc.), Gorontalo Distr. 

 (Rosenb. i), Buol (P.&F. Sarasin), Togian (Meyer S), E.Celebes (Nat. Coll.), 

 Kandari, S. E. Celebes (Beccari 4), S. Peninsula (Bernstein 1, "Wallace c 2, etc.); 

 Sula Islands (Allen a 1, Bernstein and Hoedt 1). 



Two specimens of the tj/pical Corvus enca from Java differ from Celebesian birds 

 in having the bill horn-colour towards the tip; in colour there is little enough 

 to choose between them and a South Celebes specimen, but the latter has a 

 longer tarsus. The South Celebes bird and the Javan ones are slightly more 

 bronzy above and have a slight brownish tinge below, not noticeable in the 

 North Celebes rac^. The specimens from the islands immediately off the 

 north coast seem to run larger in size (wing) than those of the mainland, thus 

 following a rule we have noticed in many other birds (though, generally, from 

 islands rather further off). No Crow has as yet been recorded from Sangi and 

 Talaut. 



This Crow is a common bird in Celebes. Mr. Wallace (Mai. Archip. 1869, I, 

 337) speaks of thousands of Crows haunting the plantations near Macassar; 

 Meyer remarked that it was common everywhere in Celebes at all seasons;
