FROM WESTERN SUMATRA. 91 



the Indian G. melanolophus , and beside careful descriptions 

 of different stages of the bird, gives many details about 

 the habits and a list of the places and dates on which 

 the bird is hitherto met with. 



Lieut. Kelham (Ibis 1882 , p. 196) mentions the true 

 G. melanolophus from Singapore. 



Mr. Gurney (Ibis 1883, p. 222) tells us that a specimen 

 of the same species ((ƒ juv.) was shot near Lemastotle 

 (Ceylon), being the first known specimen from the eastern 

 side of that Island. 



Seebohm mentions G. melanolophus from Japan, but as 

 he says nothing about the crest , it is tolerably certain that 

 he unites both species, and that his specimen belongs to 

 G. goisagi. 



Ramsay (Ibis 1884, p. 335) has received from the vici- 

 nity of Manilla a specimen »in immature plumage, which 

 agrees in the length and shape of the bill with an adult 

 specimen from Japan", while »it differs from all the spe- 

 cimens from other localities in this respect." From all that 

 and what Mr. Ramsay further says, I must conclude that 

 his specimen was undoubtedly a true G. goisagi^ which 

 might have visited the Philippines as a straggler, just as 

 well as has been the case with the specimen which has 

 been brought from the Pelew Islands. 



Cabanis (J. f. 0. 1881, p. 425) accepts the generic name 

 Bictio, proposed by Dr. Reichenow in the place of Gorsa- 

 chius , and not only considers G. goisagi a distinct species, 

 but separates the Philippine bird from G. melanolophus as 

 a new species, under the name of Butio Kutteri, on ac- 

 count of its somewhat inferior size. The result of a mea- 

 surement of the birds in our collection shows really, that 

 the specimen from the Philippines is somewhat inferior to 

 the common size of G. melanolophus (with the exception 

 of the bill), but as one of our specimens from Banka is of 

 the same size , the Philippine specimens are hardly entitled 

 to claim specific rank.
