462 Lord Walden o?i Birds from Burma.

 A.memnffiinff,IloTsf., = A. asiatica, Swains.^ occurring north 

 of the Malaccan peninsula. Since Captain Beavan first ob- 

 tained A. beavani in Maunl)hoom^ it has been found in the 

 Andamaus_, in Tenasserim, in the Bhootan Doars, the Raj- 

 mahal liills^ in Tipperah, in Cuttack, and in Siam. 



Ou a former occasion (Ann. N. H. (4) x. p. 61) I ventured 

 to assert that certain Javan birds reappeared in Burma, some 

 penetrating so far as Nipaul, although they were not known to 

 inhabit Malacca or Sumatra. The want of an authentic 

 record of all the Malaccan and Sumatran birds prevents me 

 from advancing this assertion as a demonstrated fact. Nor 

 am I able to state at what part or parts of the Malaccan pen- 

 insula these Javan forms severally reappear. But in order 

 that the assertion may be tested by others more familiar with 

 Indian and Indo-Malayan birds, the subjoined lists have been 

 prepared of the principal Javan genera and Javan species 

 which, while occurring in Burma, and in some instances in 

 regions to the west or east of that country, are not known to 

 me as inhabitants of either Malacca or Sumatra. 



Even should these lists stand the test of a rigid scrutiny, 

 they are not offered as part of the basis of any zoo-geogra- 

 phical theory, but are merely intended as a small contribu- 

 tion to our knowledge of distribution. The j)resence or ab- 

 sence of certain Sumatran or Malaccan birds in Burma pre- 

 sent equally perplexing phenomena ; while, again, some 

 Javan species are common to Java, Malacca, and Burma. 



List of Javan genera not known to occur in Malacca and 

 Sumatra, but found in Burma : — 



Brachypteryx. Dendrophila. 



Analcipus. Sturuopasior. 



Cochoa. Crypsirhiaa. 



Myiophonus. Pavo. 

 Bhringa. 



To these may perhaps be added 



Zootheru. Ftcrythrius. AUotrius.
