21. Accipiter poliocephalus Gray. 



Acc'piler poliocephaltis Gray, Proc. Zool. Soc. Lnmhm, p. 170 (Aru Islands). 



The yonug is slate-colonred on the upperside aud the under surface is white 

 with a more or less distinct creamy tinge and brownish black shaft-stripes. The 

 sexes differ only in size. 



Sharpe described a hawk from Jobi Island in Geelviuk Bay as " Astur 

 Mei/erianus " {Journal Linn. Soc. London, Zool., xiii. p. 458, 1878). Salvadori 

 afterwards identified this new bird with A. albigularis from the Solomon Islands, 

 but doubtless erroneously. The wing of A. meijerianus is, according to Sharpe, 

 315 mm. long, but Salvadori measures it even 320. This measurement is far too 

 big for A. albigularis, the largest females of which have their wings not longer than 

 256 mm. Moreover, A. meyerianus being uniform black on the upperside, appears 

 to be an adult bird, and adult albigulaiis have as a rule no black markings 

 underneath. Even the distribution " Solomon Islands and Jobi " would have 

 been a very unlikely one.

22. Accipitei' fasciatus polycryptus. 



'■'■ Astur Jasciatus" was first described by Messrs. Vigors & Horsfield from 

 "Australia" in 1827, and this name, as pointed out by Hartert in 1905, stands 

 before A. approximans on the same page, which latter name has been arbitrarily 

 chosen for these hawks by Gould, Sharpe, and others. Mr. Mathews in his most 

 recent list of the Birds of Australia, pp. 103, 104, separates three races : 



A. (or Urospiza, as he calls tham) fasciatus fasciatus (= approximans), from 

 the Eastern parts of Australia. 



A. fasciatus cruentus, from Southern and Mid-west Australia. 



A. fasciatus dii/imus,* from Melville Island and the Northern Territory. 



We have nine adult females and one adult male (besides some young birds, 

 which are of uu use for distinguishing such closely allied subspecies) from Queens- 



* I'robably misspelt for didijmus.
