of yellow at the tips of the middle pair of feathers. The wings have 

 their longest primaries slightly margined externally with whitish, and in 

 some specimens there is a slight yellow border to the secondaries and 

 tertiaries ; while younger males have the whole exterior portion of the 

 secondaries and tertiaries washed with yellowish- olive. The coverts of 

 the primaries are always tipped with yellow, producing a slight spot of 

 this hue, which does not occur (at least in the adult male of) O. chinen- 

 sis. Younger males have, as usual, the back and wings tinged with dusky 

 greenish; and in females (and perhaps still younger males), the same 

 dull colour prevails on the head and neck, the broad black occipital 

 crescent is merely indicated, the feathers of the under-parts have 

 each a black central stripe, and the tail is wholly dusky yellowish above, 

 prevailing throughout the outer webs of all the feathers, while the inner 

 webs are successively more deeply terminated with yellow, — this colour 

 being alone seen underneath, in adults of both sexes. Length about 

 eleven inches, or rather more ; of wing six ; and tail four and a half to 

 five inches : bill to gape an inch and a half, and tarse an inch. Inhabits 

 the Nicobar Islands. 



5. O. indicus, Brisson, Jerdon, ///. Ind. Orn. pi. XV: 0. chinensis 

 et cochinchinensis of India, auctorum ; le Loriot des Indes, Buffon. This 

 differs from the two preceding in its considerably smaller bill ; in the 

 yellow of the forehead extending further back beyond the eye, reducing 

 the black occipital crescent, which latter is continued forward in adults, 

 through the ocular region, quite to the nares ; in the greenish tinge of 

 the back, even of old males ; and very conspicuously in the much 

 greater extent of the yellow upon its wings, while the tail has less than 

 in 0. chinensis, and its middle feathers have rarely distinct yellow tips : 

 in 0. chinensis, and some specimens of 0. macrourus, the secondaries 

 and tertiaries are wholly deep black; whereas, in the present species, 

 the secondaries are broadly margined, and the tertiaries have their whole 

 outer web and part of the inner web, greenish-yellow ; the pri- 

 maries are tipped with the same ; and a bright yellow wing-spot is 

 formed by the tips of the coverts of the primaries. Younger males 

 have much more of the green tinge above and on the wings, and the 

 under-parts are much weaker yellow, with black stems to the breast- 

 feathers, more or less developed. They evidently increase in bright- 

 ness of colouring for several years. Females are yellowish- green
