This Crow, or rather small Raven, is a diminutive form of C. vali- 

 dus and its allies. It has no affinity with true C. enca. 



40. Calornis panayensis (128). 



Calornis chalybeus (Horsf.), Sharpe, t. c. p. 343. no. 111. 



[P. Princesa, $ , December 1877 : iris brilliant red ; bill and feet 

 black.] 



A large series is sent by Mr. Everett, which I refer to the Philip- 

 pine ratber than to the Boruean species. 



41. GRACULA JAVANENSIS. 



Corvus javanensis, Osbeck, Voy. China & E. Ind. i. p. 157, 

 "Java" (Eng. tr. 1771). 



[P. Princesa, 3, January 1878 : iris deep brown; bill fine deep 

 orange ; wattles and legs chrome-yellow ; claws dark brown. $ , 

 December 3, 1877: iris deep brown; bill red-orange; wattles 

 orange-yellow ; legs yellow.] 



These examples are not to be distinguished from Bornean, although 

 they are somewhat smaller and have slenderer bills than Javan and 

 Sumatran individuals. 



42. OXYCERCA EVERETTI. 



Oxycerca everetti, Tweeddale, P. Z. S. 1877, p. 699, t. lxxiii. f. 2. 



[P. Princesa, <3 , December 1877: iris rich deep orange-brown; 

 bill, maxilla black, mandible pale grey ; feet, legs, and claws dark 

 lead-grey. 3 juv. : iris umber-brown ; mandible blackish ; maxilla 

 black ; angle of gape pure white ; legs, feet, and claws lead-grey.J 



Oxycerca everetti is a very closely allied form of O. leucogastra 

 of Malacca and Borneo, mainly to be distinguished by the crown of 

 the head being striated in the former and uniform in the latter, and 

 the breast and general colouring being nutmeg-brown and not sooty 

 brown. These Palawan examples, although not quite identical with 

 either species, most nearly resemble O. everetti. The general tone 

 of colour is nutmeg-brown ; but the crown of the head is not 

 striated.
