was altogether paler in colour, and named it lloydi {Ibis, 1917, 

 p. 608). As various kinds of birds frequenting Kangaroo Island, 

 off South Australia, are darker than those of the mainland 

 generally, so it appears that some species found on Dirk Hartog 

 Island, off the western coast, are much lighter in colour than 

 those represented on the mainland opposite, notably, in addition 

 to the Bell-Bird, the Emu-Wren, Scrub-Wren, Field-Wren, &c. 



Pachycephala melanura, Gould. Black-tailed Thickhead. 

 P. >ii. bynoci (Mathews, A. A. R., iii., p. 137). 



Two ,3S, 3 ??, Cossack. Whitlock had previously (1917) 

 collected a mature female. The females have all the light yellow 

 (lemon chrome) under tail coverts, which obviously separates 

 them from those of occidentalis (Ramsay) in the south and from 

 the true melanura in the north. The Cossack birds may even be 

 considered a distinct species. However, Mathews has made it 

 a sub-species of melanura, the females of which have, when 

 mature, the full yellow breast of rich lemon chrome. 



Pachycephala lanioides, Gould. White-bellied Thickhead. 

 Alisterornis I. carnarvoni. 



Two c^cJ, Cossack. For previous remarks on this fine species 

 see Emu, ante, p. 7. 



Gould originally procured a single male * of this Thickhead 

 from the North-West Coast, remarking : — "It is a most robust 

 and powerful bird, and may hereafter be made the type of a new 

 genus." The new generic name, Alisterornis, has been proposed. 

 Good ; but suppose there be another Australian avine genus named 

 Alisteranus, and yet another A lister us ? Are not these three 

 similar names confusing ? 



On behalf of Mr. H. L. White I described the eggs (typical of 

 the Pachycephala), giving copious and interesting field observa- 

 tions by the collector (Mr. F. L. Whitlock) in the mosquito-infested 

 mangroves of Condon (see Emu, viii., p. 143). In the following 

 volume of that journal (pi. vii.) will be found a most excellent 

 photo. -picture of the nest and eggs, by Mr. Sid. W. Jackson, 

 R.A.O.U. 



Calamanthus campestris, Gould. Field-Wren. 



Two 3 0, I -f, Dirk Hartog ; i o, 2 $$, mainland opposite. A 

 useful series. Carter named the island form hartogi {Bull. B.O.C., 

 XXX vii., p. 5) ; but it answers to Mathews's dorrei, from the ad- 

 jacent island of that name — " differs from howei (= campestris f) in 

 having less red on the crown and being paler above " {Nov. ZooL, 

 xviii., p. 337). 



Mr. Carter likewise separated the mainland (Pcron Peninsula) 

 bird, naming it peroni {Ibis, 1917, p. 586). I think he will fmd, 



* Mr. Robt. Hall, C.M.B.O.U., described the female from Derby, 1901, 

 Victorian Naturalist, xviii., p. 30. 



t C. ho~vei, type locality Mallee, Vic, is well represented by Gould's figure of 

 campestris, " Buds of Australia," iii., pi. 71.
