way across. Tliougli so abundant in the Higlit, thry arc not at 

 all common on tlie east and west coasts, where they are replaced 

 by T. chlororhynchns. Ferguson met with them as far north as 

 Cape Naturaliste, W.A., and there can be little doubt that this 

 is the species with yellow bt^ak and yellow eyes recorded as noted 

 on the coast of New South Wales in June, July, and August 

 {Emu, XV., p. 215). 



The type locality of the species is the Cape of Good Hope, and 

 Mathews has named the Australian race T. m. impavida. 



Sub-genus Thalassogeron. 



thalassarcJic chrysostoma (Forster). Grey-headed, Flat-lnlled, or 

 Culminated Mollymawk or Albatross. 



Gould states that numbers of these birds came under his notice 

 during a voyage from Launceston to Adelaide, particularly off 

 Capes Jervis and Northumberland (i, p. 436). One collected by 

 him on the coast of Tasmania in August, 1839, i^ in the British 

 Museum (4, p. 451). A specimen was captured alive by Mr. 

 F. L. Stronach on the sand-hills at Cottesloe, W.A., in June, 1917 

 {Emu, xix., p. 59) ; I erroneously stated that it had been " picked 

 up on the beach at Fremantle," but Mr. Stronach has since given 

 me full particulars of the capture. 



The species is apparently common in that portion of the Indian 

 Ocean lying to the south-west and south of Western Australia, 

 according to W. Macgillivray's observations in June, 1919, and 

 Ferguson also observed it in that region in January, 1916. It 

 is probably the species met with on the coast of New South Wales 

 from August to the beginning of December, with grey head and 

 grey neck {Emu, xv., p. 215). 



Gould named the species Diomedea cidniinata, the type locality 

 being Bass Strait, and Mathews uses this name sub-specifically 

 for East Australian birds. The West Australian race has been 

 named by him T. c. alexanderi. 



Sub-genus Nealbatnts. 

 Thalassarche chlororhynchtis (Gmelin). Yellow-nosed or Carter 

 Mollymawk or Albatross. 



This is the commonest member of the family on the New South 

 Wales coast, outnumbering all other species by at least three to 

 one {Emu, xv., p. 215). It is met with from March until December. 

 It often enters Sydney Harbour, and, according to Ferguson, is 

 very common between Sydney and Brisbane. Gould observed 

 it off Capes Howe and Northumberland, and I have seen it in 

 St. Vincent's Gulf. In the Bight it is almost absent, but reappears 

 in the neighbourhood of Albany, and is again plentiful on the 

 west coast from Cape Leeuwin to Geraldton, whilst the bird 

 which was made the type of Diomedea carteri was captured by 

 Mr. T. Carter as far north as Point Cloates. 



The type locality of the species is the Cape of Good Hope. For 

 the West Australian bird Mathews uses the name carteri sub-
