90 COUNT T. SAL VADORI ON THE [Jan. 15, 



Islands bird belongs to a peculiar form. I sball now give a full 

 description of the adult bird collected during the ' Challenger' expedi- 

 tion, and shall proceed after to point out the principal differences 

 from the allied forms.

This species is intermediate between M. amboinensis (Linn.) and 

 M. doreya (Bp.). 



It differs from M. amboinensis (which it much resembles in the 

 light underparts) : — 



1st. In the greyish tinge of the vertex, of the occiput, and of the 

 hind neck ; 



2nd. In the more vinaceous colour of the frout neck ; 

 3rd. In the more whitish underparts ; 

 4th. In the darker hue of the back ; 

 5th. In the larger dimensions. 



From M. doreya, Bp., to which it bears a great resemblance iu 

 the upper parts, it differs : — 



1st. In the more greyish hind neck ; 



2nd. In the much less vinaceous front neck and upper breast ; 



3rd. In the more whitish underparts ; 



4th. In the lighter and more greyish tail ; 



5th. In the larger dimensions. 



13. Tringoides hypoleucus (Linn.). 



[No. 285. Eyes black ; stomach contained portion of shells. — 

 J. M/] 



14. NUMENIUS UROPYGIALIS, Gould. 



[No. 281. Female: eyes black; stomach contained Crustacea 



(crabs). — /. A/.] 



In my Catalogue of the Birds of Borneo I have referred this 

 eastern form to N. phceopus (Linn.) ; but now I think that N. 

 uropygialis, Gould, with the uropygium constantly mottled with 

 dark grey, is entitled to specific rank.
