from Koh Lak, south-west Siam, and two specimens, a 

 male and a female, liave now been sent home by Mr. Herbert 

 from Chan Tuek and Pukchau, from the same part of Siam. 

 These two latter are undoubtedly nothing but pierrei. The 

 male has a wing of 152 mm., and the female 148 mm., 

 whilst the type of pierrei, a female, has a wing of 156 mm. 

 Mr. Herbert's birds also have the pale upper and under 

 plumage of pierrei, contrasting well with ivrayi in this 

 respect. 



The other differences noted by Dr. Kloss, i. e., the paler 

 bill, nearly black centres to the forehead and dark sides of 

 head and neck^ are not present in Mr. Herbert's specimens, 

 which agree perfectly w'xih inerrei in these details. 



The wings of C. /. lorayi in the British Museum collection 

 vary between, ,$ ^ 140-141 mm., ? ? 140-148 mm., and 

 it is possible that with more material ivrayi and pierrei may 

 prove to be one and the same. C. f. flavinucha varies con- 

 siderably in the depth of colouring on the lower plumage, 

 some individuals being much darker than others, and 

 though wrtnji from the south would also appear to be mucii 

 smaller on an average than pierrei from tlio north, yet one 

 female, ivrayi, from Salauga, is the same size as Mr. Herbert's 

 bird from Chan Tuek, a very long way farther north.

Mr. Kloss, who creates this new subspecies on a single 

 unsexed specimen from Koh Lak, south-west Siam, diag- 

 noses it as bigger than C. m. malaccensis, having a wing 

 of 137 mm., and says that it differs in having the l)rea8t and 

 abdomen paler, the ground-colour being less tinged with 

 brown, and the dark bands narrower and farther apart ; 

 the nuchal crest is without spots and bars. 



There are other specimens from Siam in the British 

 JNIuseum collection, and these do not bear out Mr. Kloss's 

 diagnosis, but show, as do the other birds in this big series, 

 that all these so-called subspecific variations are merely 

 individual, occurring in some specimens throughout the
