Hab. Luzon (Meyer). 
Dr. Meyer's researches in the Philippines have added an additional member of a 
genus hitherto not known to be there represented. The small group of Pachycephaline 
birds to which the title of Hyloterpe is restricted, is now known to contain six species. 
They are entitled to subgeneric distinction. The sexes are, I believe, alike; and 
they possess this further peculiarity, that they wear, in adult plumage, a sombre 
garb recalling the adolescent and the female plumage of the true black-and-yellow 
Pachycephale. This Philippine species is a representative form of H. sulphuriventris, 
Walden, ex Celebes. Above, it differs by its plumage being olive-green, and not brown, 
and underneath by the yellow extending higher, and being much brighter. The bill 
is likewise more powerful. Seen from above, H. philippinensis is difficult to distinguish. 
from H. fulvotincta, Wallace, ex Flores; while, in the same way, H. sulphuriventris 
closely resembles H. grisciceps ex N. Guinea. Seen from below, however, the affinities 
are reversed, the Flores Hyloterpe showing a great resemblance to that of Timor, //. 
orpheus (Jard.), and the Celebean and Philippine species but differing slightly.

1 Wiegm. Archiy f. Naturg. 1847, i. p. 321, type Hylocharis philomela, 8. Miiller. Boie (Isis, 1831, p. 546) 
gave the title of Hylocharis to a section of the Trochilide. But Mr. G. R. Gray, besides adopting the title 
(Hand-list, i. p. 148) for a genus of that family, employs it again (tom. cit. p. 389) for the Pachycephaline genus 
named by Dr. Cabanis Hyloterpe, and attributes it also to Boie, with the date 1827. Dr. Cabanis (/.c.), on the 
other hand, refers the Pachycephaline genus Hylocharis to S. Miiller, of which he states Hylocharis philomela, 
S. Miiller, to be the type; and he changed the generic title, as that of Hylocharis was preoccupied. S. Miller 
published that title, without giving any characters, in his papers on his zoological discoveries in the Sunda 
Islands (Tijdschr. Nat. Geschied. en Physiol. ii. p. 331, 1835); but he called the species Hylocharis luscinia, and 
the title H. philomela is not given by him. It is probable that the two titles refer to the same species
