mm. Four females: Wing, 130-137 (133.9); outer tail feather, 335- 

 385 (365); spatula, 80-90 (85.2); middle tail feathers, 110-120 (116); 

 culmen, 20-21.5 (20.8) mm. These measurements indicate a bird 

 with a longer tail and rackets than B. r. tedirostris, as claimed by the 

 describer. 



The range is not well known, but it occurs in northern Siam and 

 probably the southern Shan States of Burma and iji northern Tonkin. 



Gyldenstolpe ^* records it from Doi Par Sakeng and Khun Tan ; de 

 Schauensee ^^ from Doi Sutep, 2,500-4,000 feet, and Chiengsen; and 

 on his third expedition ^^ from Chiengmai and Chiengdao; Lowe^^ re- 

 cords it from Umpang and farther eastward ; Deignan ^^ says that on 

 Doi Sutep it occurs in the evergreen forest above, 2,500 feet and is 

 increasingly common toward the summit. Evidently it is a highland 

 bird. 



BHRINGA PERACENSIS PERACENSIS Baker 



Bhringa remifer peracensis Baker, Bull. Brit. Orn. Club., vol 39, p. 18, 1918 

 (Telom, Perak-Pahang border). 



This group can easily be distinguished from the remifer group by 

 having the racket extending along the shaft for a much longer distance 

 and tapered off basally, making a long tapering racket; it is narrower 

 also. This great and fundamental difference, in my opinion, is more 

 than racial when it is considered that there is a long stretch of country 

 between the remifer and peracensis groups in the south and the remifer 

 group in the north and the jyeracensis group in southeastern Siam, 

 where the genus apparently does not occur. 



B. p. peracensis occurs in the mountains of the Malay States and 

 western Siam, where two males have been recorded by Chasen and 

 Kloss^^ from the Raheng District. These specimens should be 

 reexamined carefully, as they are out of its known range. 



One unsexed specimen of peracensis from Selangor measures: 

 Wing, 128; outer tail feather, 470; middle tail feathers, 107; racket, 

 173; culmen, 20.5 mm. One male of lejoli from southeastern 

 Siam: Wing, 135; outer tail feather, 507; middle tail feathers, 104; 

 racket, 265 mm; tip of bill broken. Four females (lefoli) from 

 southeastern Siam: Vring, 123-130.5 (128); outer tail feather, 295-393 

 (364.5); middle tail feathers, 106-115.5 (110.9); racket, 154-194.5 

 (172.6); culmen, 19-21 (20). Three females from southern Annam: 

 Wing, 133-135 (134) ; outer tail feather, 440;^° middle tail feather 116.5- 

 126.5 (120.7); racket, 148; '" culmen, 20-21 (20.5) mm.
