382 Viscount Waldeu on Birds from Northern Borneo. 



sianus argus (Linn.). The dimensions of the Bornean Argus are 

 considerably less. The feathers of the nape, back of the neck, 

 the interscapulars, and the scapulars have black for their ground- 

 colour, the markings being pure white. In A. argus the ground- 

 colour of these feathers is brown, and the markings are ochreous. 

 The markings in the Bornean species are of a diflferent character, 

 and are most minute and delicate. The throat, upper breast, 

 and centre of the lower breast and of the abdomen are bright 

 ferruginous, whereas in the Malayan species these parts are deep 

 ruddy chocolate. The markings are quite different, and many 

 are white. The other differential characters given by Mr. Elliot 

 are not very apparent in Mr. Everett's examples. The ocellated 

 marks on the scapulars are certainly smaller; but I can find no 

 difference in the colouring or marking of the lateral rectrices. 



The following are some of the dimensions, viz. : — 



inches. 

 Longest primary, from carpal joint . . 13"50 



Middle pair of rectrices 44*50 



Longest outer pair of rectrices .... 19'00

Two female examples ; no note of the locality, but probably 

 from the neighbourhood of Sarawak, where Mr. Wallace also 

 obtained an example {fide Sclater, /. c). The hen of this spe- 

 cies is distinguished from that of E. ignitv^ (Shaw) by the rec- 

 trices being dark brown or black.
