PSEUDOGERYGONE VIRESCENS. 435 



a differently coloured tail : G. ruficollis Salvad. has the sides 

 of head and neck, the foreneck and throat rufescent, and 

 in G. himaculata (most nearly allied to the former species) 

 the white apical spot on the outermost tailfeathers runs 

 over both webs.

Hab. New Guinea: Lobo-Bay (on the Westcoast), collected 

 by Dr. Salomon Muller in 1828 (later determined „Gery- 

 gone conspicillata (G. R. Gray)". 



Blyth's short diagnosis is thoroughly insufficient to re- 

 cognize this species, which has been placed (apparently first 

 by Dr. Sharpe) simply as synonymous with the totally 

 different Gerygone conspicillata Gray ^). In fact Ps. virescens 



1) One specimen of this species was collected on the Westcoast of New 

 Gainea (Lobo-Bay) already in 1828 by Dr. S. Muller and distinguished by 

 Temminck as new s. n. nMuscicapa decolorata'"' . — Synonymous is „Zosterops
