slight. If it is found later that the Sumatra bird is worthy of recog- 

 nition, then the name Caloramphus sanguinolentus Lesson ^* is available 

 for it. 



The form ranges from Sumatra to the Malay States and northward 

 through Peninsular Siam to southern Tenasserim. The northern- 

 most record is one from Tasan, Chumporn, Peninsular Siam, reported 

 by Robinson and Kloss.^^ 



In Borneo 0. f. Juliqinosus (Temminck) occurs. It is quite differ- 

 ent from the mainland representative, having the throat and chest a 

 bright vinaceous-rufous instead of having the throat obscurely tinged 

 with reddish.

Three males and eight females, Khun Tan, October 16-23, 1929, 

 August 27-30, 1930, and February 13, 1932 (the altitude on this 

 specimen is given as 4,500 feet); one male and one female, Khun Tan 

 Mountains, 4,300 feet. May 17, 1933; one female. Pang Meton (Doi 

 Nangka), May 3, 1931; two males, Doi Hua Mot, August 13, 30, 1934. 



This series has been compared with six males and two females from 

 China (Fukien and Szechwan), and if we allow for season there does 

 not appear to be any appreciable difference between the two series. 



Some specimens have yellowish shaft streaks on the hindneck, but 

 I believe this is an age character, as several of the birds collected by 

 Dr. Smith that have this feature ^re undoubtedly subadult; in one 

 it is a light greenish band around the nape rather than streaks; in 

 another immature there are yellowdsh-green streaks on the throat. 

 Some specimens apparently fully adult retain these streaks on the 

 hind neck, however. 



The five males from Siam measure: Wing, 137.5-146 (141.7); tail, 

 90-98 (93.6); culmen, 39-43.5 (41) mm. Seven females from Siam: 

 Wing, 132-146 (140.5); tail, 78-103 (90.6); culmen, 35-44 (41) mm. 

 Six males from China (Fukien, 2; Szechwan, 4): Wing, 143-155 (147); 

 tail, 91-108.5 (100.3); culmen, 39-43 (40.7) mm. 



This large barbet has a wide range, extending through southern 

 China from Fulvicn and Chekiang to southern Szechwan and Yunnan 

 and south through Tonkin, northern Annam, and Laos, to northern 

 and western Siam and central and eastern Burma. 



It has been taken in northern Siam by a number of collectors, but 

 always in the mountains at moderate elevations. Deignan ^* reports 

 that it occurs commonly on Doi Sutep from 2,700 to 5,000 feet; later
