HORN EXPEDITION—AVES. 
the acquisition of a large and interesting series of these birds has enabled me to 
show that it is necessary to found a new genus for the reception of this species. 
Genus Spathopterus, North. 
North, Ibis, 1895, p. 339. 
Poly teles., Gould, Proc. Zool. Soc., 1863, p. 232 (part). 
Generic Characters. 
Adult male. —Similar to those of the genus Polytells, except in having the end 
of the third primary of each wing singularly elongated and terminating in a 
spatule. 
Adult female. —Destitute of spatules. 
Young male. —Similar to the female. 
Type. — S. alexandree (In the Australian Museum, Sydney). 
Pange. —Central Australia. 
The peculiar form of the third primary in each wing of this extraordinary jiew 
genus of Parrakeets will at once serve to distinguish it fnmi Polytells, or from any 
other genus found in Australia.
