122 Campbell, Victorian and Jasmanian Birds. [-th"lan 



manian bird is somewhat larger than the mainland, and in both 

 cases the female is the lesser of the two sexes by .2 inches in the 

 wing, and instead of having the ground colour of the striped 

 throat white like the male, it is of the same dull yellow as the 

 remainder of the under surface. Seeing that in the Australian 

 Museum "Special Catalogue" (Part IV., 1904, p. 355) it is 

 deemed fit to separate the mainland form under the title of 

 C. albiloris, n. sp., it is doubtless worth noticing that the 

 specimens from which these measurements are taken are 

 practically identical except in size, that from Tasmania having 

 the lores white and not dusky brown, and that from the main- 

 land white also. The same mark, however, in the female bird 

 is dusky. 



(A few years ago a " select committee " consisting of Col. Legge, 

 Mr. A. J. Campbell, and the writer looked into the Calamanthi , 

 with the finding that there was apparently no appreciable differ- 

 ence, except in size, between the Tasmanian and Victorian 

 birds.) 



Gymnorhina hyperleuca (Lesser White-backed Magpie). — 

 Besides being considerably smaller than the Magpie of the main- 

 land, some difference is shown between specimens from the 

 north and the south of Tasmania.

Cracticus cinereus (Grey Butcher-Bird). — Another smaller 

 instead of larger insular form. 



Pachyccphala glaucura (Grey-tailed Thickhead). — The differ- 

 ence between this and the mainland species lies in the colour of 

 the tail, the former being slate-grey throughout, while in the 

 latter all but the two outer feathers are, excepting the basal 

 portion and the tip, jet black. The female of P. gutturalis has 

 the tail tinged with olive. 



Pachyccphala olivacea (Olive Thickhead). — It is worthy of 

 note that the King Island specimens are smaller than those of 

 either Tasmania or Victoria. The female of this species differs 

 in plumage from the male, having a browner mantle and a 

 dingier breast and throat. The young male, as is the case with 

 the preceding species, resembles the female for a season or 

 two. 



Acanthorhynchus tenuirostris (?) (Spinebill). — The Tasmanian 

 form of this Honey-eater was named by Gould A. dubius, being 

 smaller, shorter in the bill, but withal noticeably darker than 

 A. tenuirostris. If such as the Magpie and the Browntail 

 remain separate, this should be treated as a distinct species 

 also. The female of A. dubius is duller in plumage than the 

 male, and the bill shorter by .1 inch. 



An interesting experiment was tried with a fledgling which 

 lived for four weeks in captivity. When taken it had just left 

 the nest, and was barely able to fly. Its plumage was simply
