In a very large series of birds we possess from the Malay 

 Peninsula and its adjacent islands between the Isthmus of ICra and 

 Selangor, we have seen no examples south of Trang lacking the white 

 wing patches : they are generally largel}^ developed and these birds are 

 G. c. citrina. In Trang spotless birds, which are Blyth's Geocichla 

 innotata, occur in a minority in company with spotted ones : and 

 from the Khao Luang range, 1,200 feet, Nakorn Sritamarat, we 

 have a series of eight examples (February and March 1922) in which 

 occur a pair without spots, while the wing-coverts of the remainder 

 show all stages from obsolete to large white patches. The only local- 

 ities in which we have found alone birds referable to G. c. innotata 

 are the island of Koh Kut, South-east Siam, and South Annam. 

 Contrary to Baker's dictum (M., p. 410) spotless birds do occur in 

 North Siam (c/. I., p. 46) : this writer has- also copied Gates' quite 

 inaccurate statement (Fauna Brit. Ind., Birds, ii, p. 141) that in the 

 extreme south of Siam (i. e., South of Junk Seylon) only spotless 

 birds occur. 



In spite of the apparent evidence afforded by the birds from 

 Koh Kut and South Annam we are strongly inclined to think that 

 innotata has no real existence, even as a subspecies, and that birds 

 to which its description applies are only a stage of G. citrina.
