THE JACKSONIAN OOLOGICAL COLLECTION. 
egg of the Black-throated Grebe (Podicifes nove-hollandic). It is very glossy, and well marked all over 
with the same black wavy lines as on those of the Parra; in all probability it is the result of a cross 
between the two species, as these Grebes are very 
common on Duck Swamp, where this clutch was found. 
On the very extremity of the larger end of this egg, 
there isa clear space, upon which a perfect figure 2 
is portrayed, which also resembles a swan if carefully 
examined.

GREY GOSHAWE, 
Astur cinereus, Vieillot. 
This set of 2 rare Goshawks’ eggs was taken near F. Mott’s homestead at Byron Bay, N.S.W., by 
W. McEnerny, W. M. Parker, and Sid. W. Jackson, on zoth December, 1899. Nest was rather large 
for the size of the bird, and as usual was composed of sticks, and lined inside with several layers of 
green Eucalyptus leaves, and was placed in a tall Bloodwood Eucalypt (Eucalyptus corymbosa) at an 
altitude of 60 feet. The eggs had incubation about four days old. Specimen A. measures in inches 
= 2°02 X 1°62. 
WHITE GOSHAWK, 
Astur nove hollandie, Gmelin. 
Taken by C. Woodlands, from a tall Eucalypt near Burketown, Gulf of Carpentaria district, North 
west Queensland, on 16th January, 1898. The nest was a large stick structure, and thickly lined inside 
with a mass of green Eucalyptus leaves, and contained this handsome clutch of two eggs. We found a 
nest of this beautiful bird in the Don Dorrigo scrubs, N.S.W., during October of 1898, and after a 
climb of over go feet up a tall Hoop Pine tree (Avaucaria Cunninghamit), we found it to contain only 
two young birds. (See A. J. Campbell's book, page 5.) Specimen A. measures in inches = 1°97 
1°50. Specimen B. measures = 2°02 xX 1°59.
