Stresemann (Nov. Zool. XX, p. 340) has separated the 

 lorm from the south of the Peninsula, (type from Bentong, 

 Pahang) as Surniculus lugubris brachyurus as having a wing 

 averaging about 124 mm. with a tail always shorter than the 

 wing. He includes in this race the birds from Borneo and 

 Sumatra, confining the typical S. lugubris of Horsf. to Java, 

 Bali and Ceylon, which is rather an anomalous distribution. 



Our series from t "tie lowlands of the south of the Peninsula 

 is unfortunate] \ somewhat deficient in adult birds; a male from 

 Penang has the wing 12S, tail 127, a male from Ulu Selama, 

 wing 119. tail 116; a male from Tanjong Malim, 126, tail 123, 

 a male from Kuala Tembeling, Pahang, close to the type 

 locality, wing 119, and tail 1 14, and two males from Temengoh, 

 North Perak, wing 117, 120, tail 118. A female from Pulau 

 Jemor in the Straits of Malacca, near the coast of Sumatra, 

 has the wing 135 and the. tail 130. while two males from West 

 Sumatra have the wing 126. tail 123 and a female, tail 12 3, wing 

 123. These specimens certainly bear out Stresemann's 

 diagnosis. 



Specimens from the mountains of the Peninsula win re 

 the species breeds are however emphatically not this race ns 

 two males from the Semangko Pass on the binders of Selangoi 

 and Pahang measure wings. 146, 138; tail, 138, 135. ami must 

 be referred to the Himalaic form as also one from Taiping 

 •-hot in January, wing 143, tail 138 mm. 



S<> tar as the evidence goes it appears that two races are 

 quite distinct viz. Surniculus lugubris, Horsf. from Java and 

 Bali, which has possibly become very slightly modified 111 

 Sumatra, Romeo, ami the South of the Malay Peninsula at 

 low levels (S. /. brachyurus) and 5. lugubris dicruroides from 

 the Himalayas, through the Indo-Chinese Countries to the 

 north of th. Malay Peninsula and southwards along the mam 

 range at high elevations. Judging from analogy the Ceylon 

 and Malabarese specimens will probably also prove separable. 

 These conclusions are substantially those come to by 

 Stresemann from the study of the very large material in the 

 British and Tring Museums.
