12 THE AUSTRAL AVIAN RECORD [Vol. I 



On the other hand South-west Australian birds differ 

 from typical New South Wales birds in being smaller : 

 average wing measurement 138 against average wing 

 measurement 144 mm. ; also in being paler above and 

 below. For these I propose the name — 



CUCULUS RUBRICATTJS ALBANI, Subsp. n., 



type no. 1416, Albany, South-west Australia. 



These differences are constant, and I have birds killed 

 in every month of the year, but, as in the preceding 

 case, co-operation must be used in order to define the 

 migratory movements that take place. 



In the Cat, Birds Brit. Mus., Vol. XIX., p. 266, 1891, 

 Cuculus pyrrophanus Vieillot (Nouv. Diet. Hist. Nat., 

 Vol. VIII., p. 234, 1817) is included in the synonymy 

 of the preceding species, but a careful criticism shows 

 it to refer to the species represented in East Australia 

 by C. variolosus Vigors and Horsfield. Though it is 

 stated in the original description to have come from 

 Nouvelle Hollande, Pucheran (Rev. Mag. Zool., 

 1852, p. 560) stated that the birds were collected in 

 Java. I am accepting this statement and retaining 

 the Australian name C. variolosus for the Australian 

 bird, but must use C. pyrrophanus as the species name. 

 North has correctly pointed out that Gould's C. insperatus 

 was given to a New South Wales specimen of this bird 

 and therefore inapplicable to a New Guinea species as 

 used by Shelley in the Cat. Birds Brit. Mus. North 

 has, however, erred in suppressing Gould's C. dumetorum 

 upon examination of a few specimens. He showed that 

 Gould's measurements were all at fault, viz. 5 in. for the 

 wing in one case and 6^ in. in the other, though 

 there is only the slightest difference in that measurement 

 between the birds, according to North himself, one-tenth 

 of an inch. It does not seem to be commonly known 

 that as regards Australian birds, Gould apparently simply 

 wrote down measurements approximately, and as far 

 as I can judge, with many of Gould's specimens before 

 me, without using a measure at all. It is well known
