15, 1900; one female, Rumpin River, Pahang, June 22, 1902. He 

 gives the soft parts as: Iris deep red, carmine-red, or brown; bLU, 

 feet, and claws black. 



There is Httle or no difference in size between the sexes. 



Twent3^-two specimens from the Malay Peninsula and Tenasserim 

 measure: Wing, 175-200 (186); tail, 169-200 (181); cuhnen, 29-34.5 

 (31.5) mm. Five specimens from Sumatra: Wing, 183.5-206 (195.3); 

 tail, 182-201 (188.4); culmen, 29-35 (32.2) mm. 



These measurements indicate that the Sumatran bird may be some- 

 what larger, but the difference is hardly great enough to warrant 

 separation at this time. 



The species ranges from Sumatra and the Malay States northward 

 through Peninsular Siam to southern Tenasserim. 



Robinson and Kloss ^^ record it from Tapli, Pakchan, which is the 

 northernmost record known to me. 



Stuart Baker ^* substitutes Glenargus Cabanis, 1851, for Platys- 

 murus Reichenbach, 1850. The latter is a name accompanied by a 

 cut of the generic characters, certainly of this genus, and it cannot 

 summarily be dismissed. Sharpe ^^ fixed the type on Glavcopis leu- 

 copterus Temminck, which will have to stand unless there is an earlier 

 fixation.

PSITTIPAKUS GULARIS TRANSFLUVIALIS (Hartert) 



Scaeorhynchus gularis iransfluvialis Hartert, Nov. Zool., vol. 7, p. 548, 1900 

 (Guilang, northern Cachar). 



Three males, Khun Tan Mountains, 3,000-4,000 feet, November 21, 

 1928, May 18, 1933; one male and two females, Doi Nangka, Novem- 

 ber 17, 1930; three males and three females. Pang Meton (Doi Nangka) 

 May 1-5, 1931. 



No specimens are available for comparison except of P. g. Jokiensis 

 from Fukien, China, to which it bears a close resemblance, but it 

 seems to be somewhat smaller and the black of the forehead is nar- 

 rower. P. g. laotiana I have not seen, and it is possible that the 

 Siamese specimens belong to it. Certainly the underparts are not 

 strongly suffused with fulvous as described by Stuart Baker ,^* but are 

 nearly entirely white, some specimens with a slight buffy tinge on the 

 chest. However, several workers have identified specimens as of this 

 race and I tentatively leave it here for the present. The wings of 

 five males measure: 87-91 (88.7 mm). Besides the localities repre- 

 sented by Dr. Smith's collection, it has been taken by several collectors
