314 MESSRS. ROBINSON AND KLOSS ON 



in the males and with less black in the outer tail-feathers than in any- 

 other form except 71. m. suavis, from Borneo, which is very distinct. 

 We have examined three males from the type locality, the island of 

 Pulo Condore, off Cochin-China. 



Secondly, we consider that Viellot's citation of tlie locality 

 for his Turdus tricolor (Nouv. Diet. d'Hist. Nat. xxx, 1818, p. 291, 

 " les isles de la mer du sud "), is at least as precise as Hartert's sub- 

 seipient fixation (Nov. Zool. ix, 1902, p. 571) of " India" 



Further, the description by Scopoli in 178(J (Del. Flor. and 

 Faun. Insubr. ii, p. 97) of the Malahiirhiid an 3I'i(,scica2Ja inalaharica 

 should prevent " India " being selected for a typical locality. 



We, have, therefore, further fixed the type localit}' of M. 

 tricolor as West Java (Province of Bantam). 



This form we regard as inhabiting Western Java, Sumatra, 

 the whole of the British portion of the Malay Peninsula extending 

 on the west coast as far as the Trang Archipelago and on the east 

 coast to the Bandou group. 



Another form is found from Trang northwards over the whole 

 of Tenasserim, Southern Siam and eastward to Annam. The western 

 and northern limits are not exactly known but, fide Gyldenstolpe, 

 birds from North Siam are the Indian form. 



The Tenasserim bird' which differs from the Indian one, K. m. 

 "nialaharica, by its darker female, and from the southern form, K. m. 

 tricolor, by having the feathers of the thighs in both sexes white, 

 hardly tinged with rusty, is without a name. We have therefore 

 called it K. 'in. interposita. 



Excluding four insular forms described by Oberholser, which 

 we are not acquainted with, the recognizable forms of this species 

 are ; — 



(1). K. m. malabm-ica Scop. Peninsular India : patt of 



Burma i (fide Shavpe and 

 Hartert) ; N Siam ? 



(2). K. m. interposita R. tt K. Tenasserim, part of 



Siam, S. W. Central and East 

 Siam, Annam.
