130 LIST OF DIURNAL BIRDS OF PREY, 



Museum and described in the 'Ibis' for 1882, pp. 453, 454, 

 the only differences of marking which I observe between 

 them being on the rectrices and under wing-coverts. In the 

 Jobie Island bird the number of dark cross bars on the 

 central rectrices is eleven, and they are somewhat more 

 distinct than the corresponding bars in the Astrolabe speci- 

 men, which are only nine in number ; the subterminal bar is 

 rather narrower in the Jobie Island female than in that from 

 the Astrolabe range. In both specimens all the rectrices are 

 transversely barred, but the exterior pair on the inner web 

 only. It may be well to note that a new and partly-grown 

 rectrice in the Jobie Island bird shows the cross bars as 

 strongly marked as they are on the older rectrices. 



In both specimens the under wing-coverts exhibit trans- 

 verse bars of the same alternate tints as those on the breast, 

 these being, however, more distinctly marked in the Astro- 

 labe specimen than in that from Jobie Island. 



In both specimens the throat and chin are transversely 

 barred with alternate narrow bands of grey and pale fulvous 

 brown. 



The Jobie Island female of U. etorques is slightly smaller 

 than that from the Astrolabe Mountains, of which I recorded 

 the dimensions in the ' Ibis,' 1882 {loc. cit.) ; it measures : — 



in. 



Wing 9-90 



Tarsus 2-40 



Middle toe s.u 1-70 



Culmen without cere 0'90 



A much smaller Hawk, also collected by Mr. Bruijn in the 

 island of Jobie, and ticketed by him as a female, was added 

 to the collection in the Norwich Museum at the same time 

 as the Jobie example of U. etorques. This Hawk, which is 

 nearly adult, is, if I mistake not, an example of U. misori- 

 ensis, a species which I believe had been previously met with 

 only in the island of Misori (or Mysore) ; but as this island 

 and that of Jobie are both situate in Geelvink Bay, there is 

 no improbability in this species being found in Jobie as well 

 as in Misori.
