The Malayan form (Malay Peninsula, Java, Borneo, ami prohably also 

 Sumatra) is easily distinguishable from the North Indian tyjiical (iiiicotor by its 

 smaller size (wing, tail, bill), and duller, more greyish, under wing-coverts. The 

 under tail-coverts are apparently more buff, the bine upperside on the average 

 somewhat brighter. It is therefore necessary to separate the two forms, notwith- 

 standing the lumping of it with North Indian iinicolor by all previous authors. 



Wing 70 mm., tail (j2, bill (from base) 16|, metatarsus IT.

Niltaca decipiens is easily distingnished from typical N. grandis of India by 

 the bluish crown of the female, which is only slightly shaded with grey in the 

 Himalayan females, and by its smaller size in both sexes, the wing being about a 

 centimeter shorter. Teuasserim females, though iu size like those from Northern 

 India, have also somewhat bine crowns. N. grandis decipiens is therefore the 

 Malayan form of N. grandis grandis, e.xtcuding over the mountains of Sumatra 

 and the Malay Peiunsula.

This specimen is rather smaller than our sjiecimens from Borneo. Wing 

 58 mm., tail 39. 



Sharpe calls this bird ^' Ergthromgias miidleri (BIyth)," but BIyth gave no 

 description of it at all. (See Ibis l»7ii. p. 100.) Finsch {Notes Legden Maseani 

 xxiii. p. 38) places the species in the genns JUgenea. There is much in this ; 

 but ntoniliger, solitaria, suhmoniUger, etc., must then be removed from Digenea 

 and placed with Antliipes.

Dr. Finsch has recently {Notes Leyden Mas. xx. pp. 93 — 90) expressed his 

 opinion that M. tvestermanni should only be looked n[)on as a synonym of the 

 Indian melanoleuca. He arrived at this conclusion from the study of some Malayan 

 birds of both sexes and some Indian males onlv, finding that the colour of the
