THE YELLOW-BROWED WILLOW-WARBLER. 87 
Length about 4* 3 inchesj tail 1*7, wing 2'1, tarsus '7^, bill from gape 
•55 : the second primary is about equal to the tenth ; the first primary is 
about '55 inch long. The female is rather smaller than the male. 
There has been a considerable amount of controversy about the bird 
which Mr. Blyth intended by the name P. viridipennis. The name of Mus- 
cicapa presbytis given by S. Miiller is open to objection^ for in publishing 
it he gave no description. It is therefore fortunate that Mr. Blyth rede- 
scribed the species in 1870 under the name of S. presbytis , by which it 
ought in future to be known. 
There can be little doubt that the bird originally described by Mr. Blyth 
from Tenasserim was P. reguloides, for although the length of the wing is 
given as 2 inches^ Mr. Brooks^ who examined one of the types, says that 
it actually measures 2'25 inches. Again, Mr. Blyth states (B. Burm.) 
that the Tenasserim bird is found plentifully at Darjeeling, and Dr. Jerdon, 
who had every opportunity of examining Mr. Blyth^s types, also states 
that he obtained it there. In his description of the species he states nothing 
about any white on the tail, and it is well known, moreover, that P. pres- 
bytis has never yet been found in any part of India. 
Wallace^s Crowned Willow- Warbler was procured on Mooleyit mountain 
in Tenasserim by Mr. Davison, and he also found the nest on the 2nd 
of February. It was a globular structure made of moss mingled with 
dry leaves and fibres and lined with vegetable down. The nest was placed 
in a mass of creepers on the face of a rock and contained three pure-white 
eggs. 
Elsewhere this species is only known with certainty to be found in the 
islands of Timor and Sumatra ; but it probably has a wide range over 
the Malay peninsula and archipelago.
