vegetation of a more promising nature — large casuarinas, mallee 

 eucalypts, and callistemons. Land-birds were numerous, and 

 the many small bays offered cover for a fair variety of wading 

 birds. Mt. Button Bay, about which we spent one day, offers a 

 good collecting-ground, and a specially interesting journey 

 could be made along the north-west coast. Here we met a 

 CalaniantJms allied to if not the same as C. inontanellus of 

 Western Australia. 



The list will show the birds to be closely associated with 

 those of eastern Australia. It would be interesting to learn 

 what species annually travel along the coastal country between 

 Coffin Bay and Eucla, and when. It is a tempting strip of 

 vegetation to Honey-eaters during the spring of the year. 



Altogether we located 103 species in the southern portion of 

 the Peninsula. Other than waders and swimmers, 53 species 

 are common to area 4, and 50 species to area 9 — /.^., in each 

 case about 66 per cent. Absent from area 4 are such forms as 

 those already mentioned as characteristic of the Peninsula, and 

 Collyriocincla rufivefitris (previously not known to me as being 

 in area 6), Malurus assimilis, Sisura inquieta, Drymacedus 

 bruiineopygius, Eopsaltria griseogularis, Barnardins sonarius, 

 NeopJiema petropJiila ; while area 9 has missing from it Corcorax, 

 Petroeca hggei (represented by P. campbelli), Malurus cyano- 

 chlaniys {cyaneus), Dacelo gigas (now introduced), and Calypto- 

 rJiyncJius funereus. Of the 76 species of land forms found by 

 our party in the Peninsula, I find that areas 6, 7, and 9, in con- 

 junction, have 54 of them, thus indicating the remaining 33 per 

 cent, of the land-birds are common to area 4, and are not found 

 in areas 9 or 7. Stated further as — Land-birds of the Peninsula, 

 76 species. Areas 6, 4, 53 species ; 6 and 9, 50 species ; 6, 7, 

 9, 54 species. I.e., 4, 53 ; 6 (?) ; 9, 50, areas 4 and 9 having 53 

 and 50 of the 76 observed. 



Of the 76 species of land-birds we find eight species common 

 to areas 6 and 7 that are not found in area 9 ; eight species 

 common to areas 6 and 9, not being found in 6 or 4 ; and four 

 of the species peculiar to area 6. These may thus be shown : — 

 Areas 6, 7, 8 species ; 6, 9, 8 species ; 6, 4 species. 



Subtracting the y6 species of land-birds from the total, 103, 

 we have : — Waders and swimmers, 27 species. Areas 6, 4, 27 

 species ; 6, 9, 20 species ; 6, 7, 9, 9 species, the number of species 

 being given as common to each group of areas. It appears 

 that the whole of the waders and swimmers of the Peninsula 

 are common to area 4, as far as our observations go, while 60 

 per cent, only are common to area 9. Of the species that range 

 into area 7, and which are common within areas 6 and 9, there 

 are only nine species. This would indicate that the south-east 

 of the continent is stronger in waders and swimmers and the 

 south-west weaker in the same.
