GENUS RHIPIDURA. 75 
(the type of B. vidua, figured in the above mentioned 
plate) from the Highlands of Padang, collected by the 
Dutch Expedition through Sumatra. 
Our Sumatran specimen is not specifically different from 
R. albicollis from the Continent, of which I bad the good 
fortune to get 75 specimens in the British Museum to 
compare with, amongst them one from Perak. One might 
say that, as a rule, the Sumatran specimens, of which I 
saw one in the British Museum, would have the white 
tips clearer white and longer than those from the Conti- 
nent; I found, however, amongst the Indian birds enough 
specimens to form a series showing every degree of a 
gradation between PR. albicollis and atrata, and the spe- 
cimen from Perak certainly would belong to the latter, 
if it might be maintained as a distinct species. (See also

and Salvadori, Uccelli di Birmania, Ann. Mus. Civ. Ge- 
nova, 1887, p. 590).
