NOVITATES ZOOLOGICAE XXVI. 1919. 43 



(1) Bhringa remifer remifer. 

 Edolius remifer Temm., PI. Col. 178 (1823). 



Type Locality. Java and Sumatra. 



I designate Java as the type locality. 



This is a small bird with a wing averaging 131-6 mm. and varying between 

 128 and 137 mm. The tail is a very poor ornamental feature when compared 

 with those of birds from the north ; the outer tail feathers are only of 300 mm. 

 or under, and with small, narrow racquets seldom exceeding 50 mm. in length. 

 The birds in the collection of the Tring Museum confirm my diagnosis both in 

 this and the other races admitted by me. 



Habitat. Java and Sumatra only. 



(2) Bhringa remifer tectirostris. 



Bhringa tectirostris Hodgs., Ind. Rev, L p. 325 (1837), 



Type Locality. Eastern Nepal. 



This is on an average a much larger bird than typical remifer, though in the 

 South of Burma the two forms are very similar in size. In every case, however, 

 it has a far finer tail than has the Javan and Sumatran bird. The outer 

 tail feathers in most cases exceed 350 mm. in length, running up to 400 mm., 

 whilst the racquets are a good deal longer, generally between 70 and 90 mm., 

 and, especially, a good deal wider. 



The wing averages in llSbirds 136 mm., and varies between 129 and 146 mm. 



Habitat. Northern India from Eastern Nepal to the whole of Burma north 

 of Rangoon, Chin, Kachin and Shan States, Yunnan, and Northern Siam. 



(3) Bhringa remifer peracensis. 



Stuart-Baker, Bull. B.O.C. xxxix. p. 18 (1918). 



Type Locality. Mts. of Perak, Telom. 



B. r. peracensis differs at a glance from all other races of Bhringa remifer in 

 having the outermost tail feathers without any broad spatulae, but with the 

 terminal half, or rather more, with broad webs on either side, narrowest where 

 they commence from the practically bare shaft, and gradually increasing until 

 the two form a feather about 15 mm. in width at the widest part. If the appar- 

 ently bare webs be examined under an ordinary magnifying glass it will be seen 

 that, unlike B. remifer remifer a.nd B. r. tectirostris, there are signs of feathering 

 everywhere except for an inch or two near the base. 



In size B. r. peracensis averages in wing measurement 130 mm., and varies 

 between 127 mm. and 134 mm. The tails are very long, the outermost feathers 

 sometimes exceeding 400 mm. 



Habitat. The mountains of Perak, Telom, Pahang. 



It is quite probable that this form will be found to inhabit a higher range 

 than the more typical remifer, and may possibly extend throughout the 

 mountains of the Malay Peninsula, and we may expect the birds in the extreme 

 north and extreme south to graduate in appearance with B. r. tectirostris and 

 B. r. remifer respectively.
