Eggs. 
I 
THE JACKSONIAN OOLOGICAL COLLECTION. 
Taken from Julian Rock, in Byron Bay, New South Wales, by W. McEnerny and Sid. W. Jackson. 
We visited this small island, north of Cape Byron, on the 18th of November, 1899, and found the 
birds breeding everywhere on it. The following series of these beautiful eggs ranges from data No. 
274 to 282, and shows a truly wonderful variation in their markings, some having a white ground color, 
others stone, purplish, grey, etc. Some possess spotted surfaces, others are blotched, and look as if 
ink had been poured over them, while again some of this series possess very long wavy lines, such as 
we find on the eggs of the Spotted and Regent Bower Birds.

WHITE-SHAFTED TERNLET, 
Sterna sinensis, Gmelin. 
Taken on the oth of November, 1894, by Chas. Reid and Sid. W. Jackson, on a sand spit at 
Yamba, at the mouth of the Clarence River, N.S.W. The eggs were laid in a slight depression on the 
sand. We found many eggs, but most of them were on the point of hatching. An egg of this set 
measures in inches = 1°22 X 0°97. 
Taken by the same persons on the previous date and locality. The ground color of this set is 
much darker than those of set No. 283. The eggs vary greatly in size, shape, color and general mark- 
ings. An egg of this clutch measures = 1°33 x 0'95. 
WHITE-FACED TERNLET, 
Sterna nereis, Gould. 
Set of 2 eggs, taken near the Cocked Hat Rock, south of Byron Bay, N.S.W., by W. McEnerny, 
and W. M. Parker, on the 19th of December, 1899. Many other nests were found containg young 
birds. A specimen of this set measures = 1°40 x 0°93. 
BLACK-NAPED TERN, 
Sterna melanauchen, Temminck. 
Taken on a small island off Cape York, Torres Straits, Queensland, on the 16th of November, 
1876, by the late Samuel White, the well-known naturalist. The egg of this Tern is at all times exceed- 
ingly difficult to obtain ; I have only seen this one specimen, and regret to say it is not a perfect one. 
Received from J. W. Mellor.
