New Caledonia, Lifu, and the Neiv Hebrides. 183 



21. EopsALTRiA cALEDONicA, G. R. Gr. (= C. variegatUf 

 G.R.Gr.). 



Mr. G. R. Gray, in his diagnosis of this species (P. Z.S. 

 1859, p. 162), notes various differences between the sexes, 

 chiefly that the male has the throat white, the female pale 

 yellow. I cannot find that any of these distinctions hold ; 

 the adults of both sexes seem exactly alike, and have the throat 

 white with the faintest tinge of yellow. 



22. Pachycephala assimilis, Verr. & Desm. 



23. Pachycephala morariensis, Verr. & Desm. 



There is some variation in the breadth of the black collar 

 in the male of this species. 



24. Clytorhyncus pachycephaloides, Elliot. 



Mr. Layard has at last obtained this rare and curious bird. 

 I may note, what is not mentioned by Mr. Elliot in his de- 

 scription, nor represented in his plate, that in the adult male 

 the bill, bluish black at the base, has the lower half of a 

 semitransparent horn- colour. 



25. Artamus melaleucus (Forst.). 



26. Lalage montrouzieri, Verr. & Desm. 



Having before me a series of this bird, I observe that, while 

 the fully adult male has no trace of any other colour than 

 glossy black and pure white, many younger birds, marked as 

 breeding, have a shade of chestnut on the breast, and the 

 scapulars edged with the same. The female has the upper 

 parts umber-brown instead of glossy black, the Avhite breast 

 suffused with chestnut, and the scapulars and wing-coverts 

 edged with light chestnut. The very young birds, while the 

 lower parts are pure white, have the back thickly barred 

 transversely with pale chestnut, and the wing-coverts and 

 scapulars broadly bordered with the same. 



27. Campephaga caledonica, Gm. 



The specimens appear identical with those from the New 

 Hebrides. 



28. Physocorax moneduloides (Less.) . 



In spite of " the angle at which the gonys ascends," I do 

 think our systematists have been hard on this charming little
