318 NOVITATES ZOOLOGICAE XXV. 1918. 



character varies in ruhecnh, but the chin is almost always less whitish, some- 

 times quite as brownish as the jugulum. We propose to call this form : 



Myiagra rubecula sciurorum subsp. nov. 



for the brothers Eichhorn (Eichhorn =sciuius). 



Type : ? ad. Rossel Island, 3.iii. 1898. A. S. Meek coll., No. 1532. 



The wings of our 8 males from Sudest and Rossel Islands measure 73"5-77 

 mm., females 70'5-7o, l)ut most of them are not quite adult, showing still white 

 tips to the greater upper \ving-coverts. 



Compared with these the birds from St. Aignan Island seem to be larger, 

 measuring : 3S, wing 80, 82 ; $$, 75, 75, 75"5 mm. There are, on the other hand, 

 similar differences in size in Austraha, and we camiot, therefore, regard our small 

 series from St. Aignan as large enough to prove that their larger size is anything 

 more than accidental. Their coloration is exactly as in 31. r. sciurorum. 



The bill of Sudest Island males is described on the labels as dark slaty blue 

 with black tip, iris dark brown, feet tjlack. Females : " Iris dark brown. Bill 

 black and light horn-colour. Feet blackish slate-colour." 



We therefore recognize at present of tliis group of Myiagra : 



Myiagra rubecula rubecula (Lath.). 

 Victoria, N.S. Wales, and Queensland as far north as Cape York. 



Myiagra rubecula fapuana R. & H. 



South-eastern New Guinea. (There are some specimens in the British 

 Museum from the islands in Torres Straits which require further study, if 

 possible from larger series.) 



Myiagra rubecula sciurorum R. & H. 

 Rossel and Sudest, and probably St. Aignan, Louisiade group. 



Myiagra concinim concinna Gould. 

 Northern Territory and N.W. Australia. 



Myiagra concinna yorki Math. 



Northern Queensland from Cape York to at least as far north as Mackay. 

 (See remarks.) 



Gerygone magnirostris tagulana sulj.sp. nov. 



Formerly we had no Gerygone from Sudest Island, but now the brothers 

 Eichhorn have sent us nine good skins, shot on Mt. Riu or Rattlesnake from 

 January to April 1916. These, as one would have expected, belong to a new 

 subspecies. Compared with G. magnirostris onerosa Hart, from St. Aignan they 

 have a smaller bill, darker, duller, less rusty upperside and a less yellowish brown, 

 more whitish undcr-surface. G. magn. rosscliana has the underside, except the 

 throat, yellow. The nearest form is G. magn. conspicilhta from N.W. New 

 Guinea, but G. m. tagulana has a more greyish olivaceous tinge on the upperside
