mingled with tawny or whitish in young birds, the 
characteristic blue-grey of the head of the Indian speciés 
being confined to the sides of the face. 
Type. A male from San Antonio, Negros, Philippine 
Islands, collected by Prof. J. B. Steere 17.2.88. B.M. 
Reg. No. 96.4.15.40. 
Measurements of type. Wing 364 mm., tail 263. tarsus 45, 
bill with cere measured round the curve 35, crest-feathers 
about 55. 
Other examples from Samar, Mindanao, and Basilan 
closely resemble the type; their wings measure:—Samar 
( Whitehead) 345 mm. [| worn], Mindanao ¢ (Goodfellow) 380, 
Basilan ? (Steere) 383. 
Three other examples from Luzon ( Whitehead) appear to 
be younger birds, and have no, or but little, trace of the 
transverse banding of the lower surface. Their wings 
measure 365, 370, and 390 mm. respectively. 
With regard to the Indian Honey-Buzzard with the very 
short crest, which has been separated by Mr. Ogilvie-Grant 
(‘Ibis 1913, p. 279) from the long-crested Malay form 
under the name Pernis elliott Jerdon, 1839, there appears 
to be an older name applicable. This is Pernis ruficollis 
Lesson, Traité, 1831, p. 76; type-locality Bengal (cf. 
Pucheran, Rev. Mag. Zool. 1850, p. 212), and figured by 
Des Murs (Iconogr. Orn. pl. 14) for the type in the Paris 
Museum. 
The Indian Short-crested Honey-Buzzard should be known 
therefore as Pernis cristatus ruficollis Lesson. 
Mr. C. Causs sent the following notes on new forms of 
South and Central American birds :—~ 
The following notes are based on material which has 
hitherto been recognised as one species, Legatus allicollis. 
This species was originally described by Vieillot in 1819 
from Paraguay and the majority of authors since that date 
have thought that its distribution extended through Central 
America to Mexico.
