Raptor es in the Norwich Museum. 453 



This collar does not appear to mc to be the remains of 

 immature dress, as it corresponds in tint with the adult 

 plumage of the upper breast. 



This specimen measures as under : — Wing 7'9 inches, tarsus 

 2-20, middle toe s. u. 1-65. 



2. An adult specimen of Urospizias etorques, Salvad., 

 obtained by Mr. Goldie on the Astrolabe mountains, New 

 Guinea, and apparently a female from its measurements, 

 which are as follows : — Wing 10" 10 inches, tarsus 2*60, 

 middle toe s.u. 1'70. 



I have already mentioned [supra, p. 126) that I felt doubtful 

 of the identity of the New-Britain Hawk, which has been 

 referred to Urospizias etorques, with the true U. etorques of 

 New Guinea ; and having now had an opportunity of exam- 

 ining an adult specimen of the latter, I feel persuaded that 

 the New-Britain bird is specifically distinct. I have already 

 described the latter in my notes on New-Britain birds above 

 referred to ; and I would now suggest that this Hawk, which 

 appears to be peculiar to the New-Britain group, should be 

 named after the old navigator, William Dampier, by whom 

 those islands were discovered in 1699, and should bear the 

 appellation of Urospizias dampieri^. 



The above-named specimen of U. etorques is a somewhat 

 larger bird than the three females of U. dampieri which I have 

 described at pp. 126-128, as may be seen by a comparison 

 of the measurements which I have there given of those speci- 

 mens with the dimensions of the presumed female of U. 

 etorques particularized above. 



The other differences between the two species are pointed 

 out in my account of U. dampieri (pp. 126, 127). I have 

 there referred to the description given by Count T. Salvadori 

 of the New-Guinea U. etorques, with which the present speci- 

 men agrees, except as regards the markings on the breast and 

 underparts, of which Count Salvadori, at p. 53 of his work, 

 observes *' Questa specie non presenta mai il eoUare cervicale 

 rossigno e le fascie trasversali suUe parti inferiori :" this 



* It sliould be noted that Mr. E. P. Ramsay has recently designated 

 a species of this group from the Solomon Islands Astur jmlcheUus (J. Pr.
