48 Notices and Descriptions of various New [No. 169. 



above, with little or no trace of the occipital crescent; whitish be- 

 neath, with dark central lines ; bill infuscated, instead of pinkish- 

 white, as in the males ; and the shape of the beak will always readily 

 distinguish them from the same sex of 0. kundoo. Length of wing six 

 inches to six and a quarter in bright old males, often not more than 

 five inches and a half in younger males ; bill to forehead an inch and 

 one-eighth, or a sixteenth more. Rather a rare bird in India generally, 

 and I have never seen it from the Himalaya. About Calcutta it is very 

 rare ; but in the countries eastward of the Bay it is generally common, 

 as in the island of Ramree (Arracan), in the Tenasserim Provinces, and 

 Malay peninsula. The Society also possess it from China. 



6. 0. coronatus, Swainson ; O. hippocrepis, Wagler. With this Ma- 

 layan species I am unacquainted, and shall merely cite the following 

 passage from Mr. Jerdon's description of the last, in his ' Illustrations of 

 Indian Ornithology.' " Swainson's 0. coronatus from Java (as described,) 

 differs from our peninsular 0. indicus, in its smaller size, shorter wings, 

 tail, and tarsus, and in the narrowness of the black nuchal band. Its 

 bill appears to be somewhat larger than in ours, but shorter than in 

 chinensis. Wagler's description of 0. hippocrepis (which he considers 

 the same as chinensis, auct.,) corresponds with it in the yellow tips 

 of the central tail-feathers, and with our peninsular bird in having the 

 black ocular band extending to the nares, and in other points. As, 

 however, his specimens were obtained chiefly from Java and Sumatra, 

 it is most probably Swainson's coronatus, with which it indeed agrees 

 pretty nearly in dimensions. The latter are given as nine inches and 

 a half total length, wing five and three-tenths, tail three and a half, bill 

 to forehead an inch and two-tenths, and tarse eight-tenths." 



7. 0. tenuirostris, nobis. An evident young male, resembles the corres- 

 ponding age of 0. indicus, except in the shape and colour of its bill, in 

 the much greater extent of the yellow on its forehead, and propor- 

 tionate contraction of the black occipital crescent, also in its rump having 

 much less yellow, relieving the greenish hue of the back and wings. As 

 in the young male 0. indicus, and fully adult 0. chinensis and 0. macrou- 

 rus, the black of the lores is not continued forward to the nares ; but the 

 separation of colours is abrupt and decided, probably indicating a simi- 

 larity of extent in the adults : the whole crown is yellow, the black of the 

 occiput not rising above the level of the eye. Wing mostly greenish, the
