addition to the British Museum. The collection contained 

 two specimens — a young male, wrongly marked " 'i ," and an 

 immature bird — both procured by Dr. Forbes at Sogeri in 

 the Astrolabe Mountains. 



The adult male from the Iwaka Kiver seems to agree with 

 the plate given by Finsch and Meyer (op. cit.), and with the 

 description furnished by Shelley in the Catalogue of Birds : 

 but the narrow white tips of the tail-feathers are neither 

 figured nor described. 



The bird described by Shelley as an adult female " with a 

 broad, glossy greenish-black collar at the base of the neck " 

 is, as stated above, certainly immature and almost certainly 

 a young male and not a female as determined by the collector. 

 Dr. Forbes's specimen is also figured by Sharpe in Gould 

 (op. cit.) as an adult female. In the female specimen from 

 Wakatimi, which appears to be an adult, the entire head and 

 neck are uniform brown, almost concolorous with the back, 

 and the throat is grey mottled with whitish-buff, with the 

 exception of a few buff feathers with broken ends which are 

 apparently remains of the immature plumage. There is a 

 distinct whitish band across the cheeks, as in the male, but 

 less clearly defined, and bordered above and below by the 

 ear-coverts and lower parts of the cheeks, which are brown 

 like the crown. Messrs. Rothschild and Hartert have, I find 

 arrived at the same conclusion. 



The male (b) measures : — Wing 106 mm., tail 97. 



The female (a) measures : — Wing 104 mm., tail 84. 



The birds procured by Dr. Forbes at Sogeri measure ; — 



? Immature male (marked female) : Wing 99 mm., tail 88. 



Immature (sex not marked) : Wing 102 mm., tail 86. 



Count Salvadori gives the wing-measurement of the type- 

 specimen as 111 mm. This apparent difference in size is 

 probably due to a difference in his method of measuring over 

 the wing. The type-specimen is said to be a female, but has 

 the top of the head, nape, and moustachial streaks shining- 

 black as in the male. In this case also I have very little 

 doubt that a mistake has been made by Beccari's collector in 

 ascertaining the sex.
