Gruinea,' iv. pi. 56 (1882), is clearly an adult and very 

 different in appearance from the young of H. nigrocyaneus, 

 though the latter has the underparts suffused with dull 

 chestnut. This error has recently been corrected \_cf. Bull. 

 B. 0.0. XXXV. p; 33 (1914)]. 



In the Tring Museum there are at the present time two 

 adult males of H. quadricolor from North-east New Guinea 

 which exactly resemble Gould^s figure. These are without 

 doubt perfectly adult birds, and represent a very distinct 

 species. The female of this species, according to Berlepsch 

 (J.f. 0. 1897, p. 90), can scarcely be distinguished from the 

 female of H. nigrocyaneus ; the onlv specimen known at 

 present is in his collection.

As might be expected, New Guinea examples of H. sordidus 

 belong to the larger race of this species, which ranges from 

 the Aru Islands to the Monte Bello Islands, Melville Island* 

 North Australia, and Queensland. It was previously un- 

 known from New Guineq.. 



In the birds from the Mimika River the wing-measure- 

 ments are respectively -.-r-a. ^ 110 ; b. ^ 107 ; c. ? 104 

 mm. 



Dr. Hartert records a specimen from Dobbo, Aru Islands,, 

 with a wing-measurement of llCi mm. ; while in the Britisli 

 Museum Collection the largest examples are from the Hope 

 Islands, off Cape Tribulation, Elast Queensland — a male and 

 female collected there by Macgillivray measuring respectively 

 112 and 115 mm. 



In some specimens, however, the wing-measurement is 

 much smaller, and two from the Aru Islands measure
