BIRDS FROM SIAM AND THE MALAY PENINSULA 103 



on the crown instead of the prussian red of the other three specimens. 

 I tliink tliis is due to age or fading, however, as there are some prussian- 

 red feathers coming in here and there. 



The wings of the four males measure: Trang, 152; Singapore, 144; 

 Sumatra, 149; Banka, 15G mm. 



The Trang specimen is the only record for Peninsular Siam, other 

 than the one for Puket, c[uoted by Gyldenstolpe.^^ The latter I have 

 been unable to trace. 



The form ranges from southern Tenasserim through Peninsular Siam 

 to the Aialay States, Sumatra, Nias, Banka, and Billiton. It has also 

 been recorded from Cocliinchina. 



Another form, Dendrophassa Julvicollis baramensis Meyer is found 

 in northern Borneo. The Nias bird has been separated on the strength 

 of a single female as Dendrophassa fulmcolUs melopogenys Obserholser. 

 The series of this sex at my command is too small to pass upon its 

 validity. 



DENDROPHASSA BISINCTA PRAETERMISSA (Robinson and Kloss) 



Treron bisinda praelermissn Robinson and Kloss, Journ. Federated Malay 

 States Mus., vol. 10, pt. 3, p. 203, 1921 (Koh Lak, southwestern Siam). 



One male. Ban Hin Ngom, February 25, 1929 ; one immature female, 

 Pak Bhayoon, July 4, 1929; one male and two females, Sam Roi Yot, 

 November 11, 1932. 



The wing in the males measures 153 and 162 mm. The miniature 

 female is too young to be of any service for comparison. 



A male collected by Dr. W. L. Abbott at Bok Pyin, Tenasserim, 

 February 16, 1900, is more yellowish about the throat, forehead, and 

 lower parts, especially the belly, when compared with the Siamese male. 

 It measures 167 mm in the wing. 



Robinson and Kloss have recorded it from Trang,^'' Ghirbi,^^ and 

 Delisle Island and Koh Lak "; Gairdner " from the Ratburi and 

 Petchaburi Districts; Barton ^* hsts it from the Raheng District. 

 Whether Robinson's records from Ok Yam " and from Lat Bua Kao 

 and Koh Mesan ^^ belong here or not, I cannot say; Robinson and 

 Kloss " were apparently in doubt. They state that the wing is 

 smaller, always under 150 mm. With these left out as doubtful, then, 

 the range of tliis form extends from Selangor north through Peninsular 

 Siam to southern Tenasserim and western Siam.
