DISTRIBUTION OF ASIATIC BIRDS.

 mannicus, Francolinus phayrei, Oxylophus jacobinus. 



Of the Irrawaddy north of Bhamo we know nothing ; but it may 

 be safely assumed that the character of the avifauna becomes more 

 and more Himalayan as the great mountains which hem it in on the 

 north and west are approached. 



The birds collected by Dr. Anderson on the hills between Burmah 

 and Yunnan prove to a certain extent that this is the case, and 

 make us very anxious to know more about them. 



In Mr. Blyth's list, I find, if the waders and water-birds are 

 omitted, that about 363 species are recorded. 



per cent. 



Common to India and the Malay peninsula 97 26 - 5 



Found in India 193 53'5 



Found in the Malay peninsula 27 7*5 



Peculiar to Burmah, or Burmah and Ten- 

 nasserim 46 1 2*5 



Thus it appears that in Burmah, Aracan, and Pegu the Indian 

 birds are to the Malayan as 7 to 1, a much larger proportion than I 

 should have expected. 



Some of the most remarkable of the species peculiar to this 

 region are : — 



Rhyticeros plicatus, Bl. Pomatorhinus hypoleucos, Bl. 



Megalaima cyanotis, Bl. Pyctorhis albirostris, Jerd. 



Mulleripicus crawfurdi, Gr. Ixos blanfordi, Jerd. 



Gecinulus viridis, Bl. Iora lafresnayi, Hartl. 



Lyncornis cerviniceps, Gould. Temenuchus burmannicus, Jerd. 



Crypsirhina cucullata, Jerd. nemoricola, Jerd. 



Pitta cyanea, Bl. Passer Jlaveolus, Bl. 



A nthocincla phayrei, Bl. Arachnothera aurata, Bl. 



Culicipeta tephrocephalus, Bl. Polihierax insignis, Walden. 



JMuscitrea cinerea, Bl. Francolinus phayrei, Bl. 



Sitta neglect a, Walden. Turnix blanfordi, Bl. 



Tennasserim. 



The Tennasserim provinces, which, as I here take them, extend 

 from about the latitude of Martaban to the isthmus of Krau, though 

 very similar to Burmah, show, as might be expected, a marked 

 diminution of Indian birds and a corresponding increase of 

 Malayan ones. 



This is more particularly the case in the mountains of the south, 

 where Col. Tickell, the only naturalist I am aware of who has 

 visited these hills, found, besides other Malay forms, no less than 

 7 of the 9 known species of Broadbills (Eurylcemidce), a family which 

 is only represented in the Himalaya by 2 species. 



In the same hills, however, which reach an elevation of about 

 7000 feet, Col. Tickell got new species of Trochalopteron, Poma- 

 torhinus, Pteruthius, Sibia, Garrulax, and Machlolophus, all showing 

 a strong affinity with the Eastern Himalaya. This leads me to
