2, PsruDOGERYGONE SYLVESTRIS (Potts). 
Gerygone sylvestris Potts, Tr. New Zeal. Inst. v. p. 77 
(1873). 
Pseudogerygone sylvestris Lorenz-Liburnau, Ann. Hofmus. 
Wien, xvii. p. 305, pl. xii. fig. 1 (1902). 
Type. ¢ adult. Between Okarita and Lake Mapowrika, 
west of South Island, 20th December (7. H. Potts). 
Adult male (breeding-plumage). Tris blood-red. Above 
dark olivaceous, shading into “ yellowish” on the upper tail- 
coverts; cheeks dark grey, darkest in a line from the gape 
through the eye; chin, neck, and breast pale grey; abdomen 
and under wing-coverts white. 
Presuming that the specimens procured by Reischek at 
Chalky Sound are typical examples of P. sylvestris (Potts), 
I cannot find any definite character by which that species 
can be separated from examples of P. flaviventris from the 
North Island. In the female specimen from Chalky Sound 
the ear-coverts appear to be rather more olive, while in 
P, flaviventris they are grey, but this difference is slight. 
3 2? adult. Chalky Sound, south-west of South Island, 
January 1887 (4. Reischek). 
The description of the female specimen kindly sent me 
for examination by Dr. Lorenz is as follows :— 
Adult female. Colour of iris not recorded. Above olive- 
brown, becoming yellowish-olive towards the tail; lores 
dark grey; chin, throat, and breast grey ; abdomen pure 
white, flanks * very pale cream-coloured. 
3. PsEUDOGERYGONE MACLEANI, sp.n. “4 
Type. ¢ adult. Maungahaumia, 2000 feet, north-west 
of Poverty Bay, north-east of North Island, 8th July, 1906 
(J. C. McLean). 
Adult male (winter plumage). Tris dull yellowish-pink. 
Above olive-brown, somewhat brighter on the lower back 
and rump ; lores conspicuously blackish; superciliary stripes, 
cheeks, ear-coverts, chin, throat, and sides of the breast 
* In the original we find “die Flecken sind sehr blasscréme.” 
No doubt the word “ Flecken ” is a misprint.
