MR. F. LENEY ON ADDITIONS TO NORWICH CASTLE-MUSEUM. 459 
I am indebted to Mr. J. H. Gurney for the following interest- 
ing notes on two species of Birds of Prey acquired by him lor 
the Museum, Spiziapteryx circumdnctus , and .4 ccipiter salvini. 
“ In November last, Mr. W. F. Rosenberg received a con- 
signment of Bird skins from the Argentine, South America, 
which included a pair of Spiziapteryx circumcinctus, Kaup, 
a species described as long ago as 1851, and the only one of 
its genus. These birds, I am happy to say, have been secured 
for the Castle-Museum, they are about the size of an English 
Merlin with white rumps and broad white bars on the tail, 
but the two middle tail feathers are black in both of them. 
Of the two the female is considerably the larger. Neither 
of them shows the double notch in the upper mandible dis- 
tinctly, and this leads me to think that they are not adult ; 
in Martorellis' plate (Soc. Lig. di Sc. Naturali e Geo. X) 
this feature of the beak is a good deal plainer, and the black 
on the tail is also more extended. The tickets state them to be 
male and female, shot respectively on the 28th January and 
the 1st of February, 1906, at Isea Yaen. Santiago, which is 
on the Pacific side of the Continent. My father’s observations 
on this very distinct form, of which he never possessed an 
example, will be found in ‘ The Ibis ’ for 1S81, p. 275 : it is 
rather singular that so many years should have elapsed before 
we acquired a bird which in its own country is no doubt 
common. My father places it next to Dissodecles , an African 
genus ; it also approximates to Harpa ; but that its characters 
entitle it to stand alone is evident. 
Accipiter salvini, Ridg. the Venezuelan representative of 
A. chionogaster, from which this small Hawk differs in its 
deep rufous tibiae, dusky auriculars, and narrower bars of 
grey on the tail, is separated from the latter in Sharp’s 
‘ Handlist of Birds ’ (1899), and in my father’s ‘ Diurnal 
Birds of Prey’ (1884)— but cj. ‘Ibis,’ 1802, p. 328. It will 
probably hold its ground as a sub-species, but not more.” 
Mr. Edward Knight gave a nestling and five eggs of the 
Black Swan ( Cygnus atratus) laid in confinement, and Mr. 
H. H. Halls, a Hoopoe ( Upupa epops ) which was shot at 
Lakenham, Norwich.
