VISCOUNT "WALDEN ON THE BERDS OF CELEBES. 79 



Calornis, G. R. Gray. 

 113. Calornis neglecta, n. s. 

 Calornis obscura, var., Wallace; P. Z. S. 1863, p. 343. 



Hab. Celebes (mus. nostr.); Sula Islands {Wallace). 



Having carefully compared examples of nearly all the described species of this 

 genus, I have no hesitation in considering the Calornis of Celebes and the Sula 

 Islands distinct. In colouring it most nearly approaches C. chalyhea (Horsf.), ex 

 Java, with the allied races from Sumatra, Malacca, Borneo, and Cambodja; but its 

 dimensions are much gi'eater. From C. obscura (Forst.), ex Gilolo and Batchian, it 

 can be readily discriminated by its bright green colouring. From all the members of 

 the C. metallica group it may be known by the total absence of any kidescent colours. 

 It perfectly agrees with examples from the Sula Islands. 



The individuals on which this species is founded were sent from Menado in a 

 box which contained nothing but Celebean birds. Notwithstanding, therefore, Mr. 

 Wallace's statement (Mai. Archip. i. p. 431) that the genus does not occur in Celebes, 

 we may, I venture to think, conclude that that island is not an exception to the 

 general rule which prevails in the geographic distribution of Calornis. 



The following attempt at an analysis of the species belonging to this difficult genus 

 may perhaps assist in clearing up the confusion in which the synonymy of its members 

 is involved. All the species are divisible into two distinct groups: — first, those in 

 which the plumage is uniform green, varying from light to very dark green ; secondly, 

 those which have, added to the prevailing green colour of the plumage, metallic reflec- 

 tions of purple and violet. The uniform green species may be further subdivided into 

 light green and dark green; while the metallic-green species are usually also distin- 

 guished by having the middle pair of rectrices much prolonged. In general terms it 

 may be said that the first subdivision embraces all the Indo- Malayan, the second and 

 third all the Australian forms.

4. Calornis affinis, A. Hay, " Tipperah, Arracan, Tenasserim, Nicobars." 



It is very questionable whether these last three species are separable. To them
