The tliree birds from the upper Chindwin are huge, having 

 wings of 157, 159, and 165 mm., and if these three were 

 eliminated, we shouhl not have any very great difference in 

 size between the most northern birds and. any other areas 

 north of 10°. I therefore leave them for the present all 

 under one name. If eventually the extreme northern birds 

 have to be separated from the central and southern Burmese 

 and Siam birds, the latter will have to be given a new 

 name, as the northern form will bear the name intermedia, 

 which was originally bestowed upon a northern Arrakan 

 bird. 



I retain the following species and subspecies : — 



(1) Tiga shorei. 

 Vide above. 



(2) Tiga javanensis javanensis. 



Picas javanensis Ljungh, K. Vet. -Ac. Nya Haudl. xviii. 

 1797, p. 137 : Batavia, Java. 



Chrysonotus tridactylus Swains. Class. Birds, ii. 1837, 

 p. 309: Java. 



Picas tiga Horsf. Trans. Linn. Soc. xiii. 1822, p. 177 : 

 Java. 



A very small bird, with wing averaging rather under 

 130 mm., and varying between 118 and 139 mm. 



Habitat. Java, Sumatra, and Malay Peninsula, south of 

 lat. 10°. 



(3) Tiga javanensis borneensis. 



Ti(/a javanensis burneensis Dubois, Ornis, xiv. 1907, 

 pp. 371, 522 : Borneo. 



This is a tiny bird, the wing averaging under 124 mm., 

 and only varying between 118 and 130 mm. It also differs, 

 however, very distinctly in coloration, having the back and 

 wings much lighter with practically no red or bronze tint. 

 Thus, if two series of birds are laid out on a table, the one 

 from Borneo and the other, say, from Malacca, the former 

 appears to be yellow-green above, and the latter red-gold. 



Habitat. Borneo only.
