blackish upper parts, particularly the pileum and that part of the 

 back just below the white collar; the whitish superciliary s-tripe less 

 distinct; the supraloral spot and white cervical collar more deeply 

 tinged Avitli ochraceous or buff. From Sauropatis chlorls sordlda it 

 may be distinguished by its much smaller measurements ; also, in the 

 male, by the darker, more greenish (less brownish) upper surface, 

 especially on the pileum; evident white superciliary stripe; less 

 greenish (more blackish) ear-coverts; more bluish (less greenish or 

 brownish) superior wing-coverts; and rather more greenish wing- 

 quills; and, in the female, by darker, more blackish (much less 

 brownish) superior surface; more greenish (less bluish) wings; less 

 greenish (more blackish) ear-coverts; more buffy or ochraceous- 

 washed cervical collar and supraloral spot; and the presence of a 

 more or less well-indicated superciliary stripe. 



The female of Sauroi^dtis chlorls colonus differs from the male in 

 having the upper parts much darker, more blackish, particularly on 

 the pileum and upper back; wings above duller, less bluish (more 

 greenish) ; auriculars somewhat more blackish (less washed with 

 green; only very slightly so tinged even in the male); supraloral 

 spot and whitish cervical collar more washed with buff or ochraceous ; 

 and throat less purely white, more creamy or buffy. 



As in most of the forms of this species, there is much individual 

 variation in color, both in the male and female ; this involving chiefly 

 the bluish or greenish shade of the upper parts, including the wings, 

 and, particularly in the female, depth of the buffy suffusion on the 

 white cervical collar, and the extent of blaclrish on the back below 

 this collar. 



No specimens have been examined from outside the Louisiade 

 Archipelago; in fact, this race has not been recorded from elsewhere. 

 It is fair to presume, therefore, that Sauropatis chlorls colonus is 

 confined to these islands. 



Detailed measurements are as follows:
