more particularly, in search of food. A Myopornni seed was found in the 

 intestine of one. In spite of the island being uninhabited, they were unduly 

 wary; more so, in fact, than on the mainland. Three birds were shot, two 

 females and a male ; iris, brown in one female, light brown in the other two 

 birds ; bill, in all brown above, pallid below except the tip ; pharynx, yellowish 

 flesh ; legs, pallid brownish-white to pale brown. Total lengths : female No. 2, 

 116 cm.; male, 12 cm. Spans of outspread wings: female No. 1, 16-3 cm.; 

 female No. 2, 16-5 cm.; male, 18-2 cm. Weights: female No. 1, 10 grms. ; 

 female No. 2, 11 grms. Ts.. 374° C, 403° C, and 391° C, respectively. 

 No ectozoa and no entozoa detected in any. 



Corvus coronoidcs, Vig. and Horsf. (Australian Crow). Controversy still 

 rages as to whether in Australia we have two species of large Crows or only 

 one species, but that a variable one. All ornithologists agree that the small 

 white-eyed Crow, Corvus bennetti, North, is a definite species differing not 

 only in size but in habits from the larger Crows. At a recent meeting of the 

 South Australian Ornithologists' Association the pros, and cons, for a single 

 species of large Crow were fully discussed, and the question was finally left 

 undecided. The colour of the iris, it is clear, counts for nothing, immature 

 birds having a brown iris and mature ones a white. The presence of hackles 

 on the breast seemed also to be a matter of age. The colour of the bases of the 

 feathers of the neck and back has been relied on as a guide. In some birds 

 this is white, in others it is greyish, but the grey tint varies in degree. These 

 grey-feathered birds are spoken of as Ravens, in contradistinction to the white- 

 feathered Crows, so the depth of grey would necessitate considering some speci- 

 mens as more "ravenish" than others. As the company of Crows on Pearson 

 Island, probably some 30 or 40 in number, might be looked on as possibly 

 having all had an origin from common parents, and consequently as all belonging 

 to one species, several birds were shot in order to note any differences in 

 individuals. All three birds turned out to be males, and all three had unduly 

 large bills. One bird was a little smaller than its fellows and was obviously 

 not mature. It differed from the others in having brown eyes instead of white 

 ones, an absence of hackles on the breast, and an irregular pigmentation of the 

 pharynx and tongue, instead of a uniform black tint. All three birds had grey 

 bases to the feathers. 



The following data were noted in connection with the three Crows shot : — 

 Adult male No. 1: Iris, white; bill, legs, and pharynx, black; total length, 

 485 cm. ; span of outspread wings, 96 cm. ; mites on wings ; mallophaga ; 

 nematodes in stomach and oesophagus. Adult male No. 2: Iris, white; bill, 

 legs, tongue, and pharynx, black ; total length, 56 cm. ; span of outstretched 

 wings, 104 cm. ; mallophaga present ; cestode ; food present, the bones and fur 

 of a rat. Immature male : Iris, dark brown ; bill, black inside and out ; tongue 

 and pharynx whitish with irregular black patches; legs, black; total length, 

 54-5 cm.; span of outspread wings, 985 cm.; T., 41-6° C. (hot day). In the 

 stomach, a number of leaves apparently of Melaleuca and Chenopodiaceous plants, 

 but no animal matter. An occupied nest was seen on the north part of the 

 island, and Professor Wood Jones found these birds nesting in Casuarina on 

 November 25. 1920. 



Stiirnus vulgaris (English Starling). A small flock was seen flying on two 

 occasions over the southern part of the island. This record cannot be considered 

 as established beyond all doubt. 



Passer domesticus (House Sparrow). This record is very doubtful. A 

 fleeting glance of two or three birds that suggested sparrows and a note uttered 

 which was also suggestive is all we have to go on. They were not seen again.
