belong to the raoe wliich was named C. m. lemniscatus bj- 

 Raffles. In one of the Bornean specimens, however, there 

 is a small white patch on the outer webs of the outer pair 

 of the tail-fcathers. Thus it seems as if this character is not 

 constant, and therefore I think it is wisest not to spht this 

 beautiful species into geographical species mainly based upon 

 the amoiint of white on the tail-feathers. In size as well as 

 in other particnlars the Bornean specimens agree well with I 

 those from different parts of the Mala}^ Peninsula. 



51. Euryliemus ochromelas Raffl. — 1 J" ^V^ 1915; 

 1 (/ 17^ 1915; 1 $ 24y^ 1915. Iris: yellow. The males of 

 this beautiful Broad-bill are distinguished from the females I 

 by having a black gorget below the whitish collar. The 

 extent of this black gorget seems to be rather variable. In 

 some specimens it is very broad but in other — most pro- 

 bably younger individuals — it is rather narrow, though 

 always complete. In the females the black gorget is inter- 

 rupted in the middle. | 



52. Calyptomeua riridis Raffl. — 1 ^ ^'^ 1915; 1 ^ 

 ^Vi 1915; 2 $$ i-Vi 1915; 1 $ ^^^ 1915. Iris: brown. The 

 Green Gaper is common every where in low country through- 

 out the Peninsula though it is getting rather rare in the 

 northern districts. Robinson and Kloss record it as 'not 

 numerous in Träng', and during my stay in the Siamese 

 Malaya north of that district only a single specimen was 

 sliot. 



53. Tliriponax jayeiisis jayensis Horsf. — \ ^ ^/o 

 1915. Iris: yellow. Wing: 224 mm.; Culmen: 52 mm. A 

 single specimen of this somewhat rare Woodpecker, which 

 inhabits southern Tenasserim, the Malay Peninsula, Borneo, 

 Sumatra, Java, Bänka, Biliton, the Lingga- and the Natuna 

 Islands. North of these localities it is replaced by Th. 

 javensis feddeni Blanf. of which I obtained specimens in 

 Northern Siam. This latter species may alw^ays be distin- 

 guished by having the lower back almost pure white, while 

 in the true javensis the lower back is black. 



54. Tiga javanensis Ljung. — 1 5 ^V-'» 1915. Thisfine 

 Woodpecker generally occurs throughout the Peninsula, though
