314 NOVITATES ZOOLOOICAS XXV. 1918. 



Cracticus lousiadensis Tristr. 



The adult female is exactly like the adult male, only smaller. The bill is 

 slightly shorter. The wing in 6 fully adult males measured 168-171, in 2 fully 

 adult females 162-lfi5'5 mm. In both sexes there is sometimes an irregular 

 small white spot in the middle of the breast, but more often it is wanting. 



Graucalus papuensis louisiadensis Hart. 



Oi-aucalus hi/poleiicus louisiadensis Hartert, Nov. Zool. 180S. p. 524 (Sudest Island). 



A fresh series fuUy confirms the differences of this subspecies. This as well 

 as others are subspecies of papueTisis. Cf. Rothschild & Hartert, Novitates 

 ZooLOGiCAE, xxiii. p. 290. 



Edolisoma morio tagulanum Hart. 



Edoliosoma amboinenu tagulanum Hartert, Nov. Zool. 1898. p. .'324 (Sudest Island). 



Some more specimens confirm the original diagnosis. Hartert now con- 

 siders tagulanum and others to be subspecies of E. morio. 



Lalage karu pallescens Rothsch. & Hart. 



Lalage karu iiallescms Rothschild & Hartert. Bull. B. O. Club, xxxvii. p. 17 (January 1917 — St. 

 Aignan and Sudest Islands. Type: Sudest). 



Our latest study of the Lalage harii group with all our recent material showed 

 the necessity of separating this form, the differences of wliich had akeady been 

 noticed in 1898. 



Monarcha cinerascens rosselianus ? 



Besides the two males collected in 1898 (both immature), we have now 

 received three more specimens : 



3 imm. Mt. Riu or Rattlesnake, Sudest Island, 24.iii. 191G. No. 7307. 



3. Sudest Island, 31. i. 1910. No. 7150. 



?. Sudest Island, 30. i. 1916. No. 7147. 



The last two specimens appear to be fully adult, except for one to two of the 

 larger upper wing-coverts, which are still brown, being remnants of the juvenile 

 phimage, and that the base of the lower mandible is whitish in both, but in vary- 

 ing degree, and not sharply divided as in most adult M. cinerascens inornatus. 



These specimens have given us some trouble. It is peculiar that of thirteen 

 sldns from Rossel Island not one has a whitish base to the under mandible, 

 not even an immatme bird. It is therefore not impossible that the form from 

 Sudest differs in this respect from true M. cinerascens rosselianus, but more 

 hkely this pale base of the mandible is a remnant of the juvenile age. 



In Novitates Zoologicae, 1915, p. 34, we have already called attention 

 to the fact that a series from Dampier Island had the bases of the bill light- 

 coloured, though at least two showed no other trace of youth. But in that case, 

 too, we had not sufficient evidence to show that this is a racial peculiarity. 



We have this time not received any specimens of Monarcha melanopsis from 

 Sudest Island, of which a pair were taken in 1898. There is no doubt that 

 M. melanopsis has sometimes a grey throat and then looks almost exactly like
