each a few millimetres in length, except where the shell has been secreted in little warty 
excrescences, forming in some examples a roughness over the whole of the larger end 
of the egg, but in others appearing only here and there, collected sometimes at the 
smaller end, sometimes in the middle, and sometimes being absent altogether. In one 
or two specimens the shell is secreted irregularly, so that raised streaks or faint ridges 
appear running down the shell from one end to the other ; the surface is therefore coarse 
in texture, rough, and carunculated, until weathered, when it presents an unusually 
smooth and polished appearance with the longitudinal pores particularly noticeable. 
Below is a list, with the measurements and characters of each egg in the series 
which we obtained, with measurements also of the Drayton egg, and of a series of 
King Penguins’ eggs from the Macquarie Islands for comparison. 
Emperor Penauins’ Eces. 
No. 1. 13*1cm. X 8*3cm. Smooth, bare of chalky covering over the pointed half. Few 
chalky nodules. 
No. 2. 12'0cm. X 8'2cm. Very rough, thick, white, chalky covering. Infinite number of 
nodules. Egg-shell itself pale greenish white. 
No. 3. 11:15 cm. x 8°45 cm. Many nodules, forming a ring round the widest part of the egg. 
Dirty white, chalky covering thick on the blunt end. 
No. 4. 11:0cm. x 7°7cm. Nodules collected at the sharper end. Chalk covering thin. 
No. 5. 12°8cm. x 7°75 cm. Chalky covering all worn off. Shell surface freely pitted with 
longitudinal pores a few mm. in length. 
No. 6. 12°3cm. x 83cm. Many nodules. Thick, chalky covering. Seventeen or eighteen 
longitudinal raised streaks down the length of the shell. 
No. 7. 12°15 cm. X 8°25 cm. Dirty greenish chalk all over. Very few nodules. 
No. 8. 12°2cm. x 8°2cm. Scattered nodules, few. Chalk uniform, but thicker at the sharper 
end. 
No. 9. 10°7cm. X 8:0 cm. The smallest in the series (Fig. 1, Pl. VI.). 
No. 10. 12°8cm. x 8°6cm. Thick white chalk all over, and multitudes of nodules, all covered 
by the chalk. 
No. 11. 12:05 cm. xX 8'1 em. Nodules in a ring round middle part of egg. Chalky concretion 
at each end. 
No. 12. 11°0cm. x 7°5cm. Many nodules, chiefly round pointed end and middle, in a band. 
No. 13. 11°9cem. X 8°2cm. No nodules. Chalky covering at both ends. 
No. 14. 11°75 cm. x 8°45 cm. Nodules only at sharp end. Chalky covering at both ends. 
Longitudinal pitting marked. 
No. 15. 13°lem. X 8°3cm. The largest in the series (Fig. 1, Pl. VII.). 
No. 16. 12°5em. xX 8'5em. Thick chalky covering, and many nodules (Fig. 2, Pl. VI.). 
No. 17. 12°5cm. xX 8*5 cm. Marked with slightly raised longitudinal strie (Fig. 2, Pl. VII.). 
Drayton Egg. 10°9cem. x 7°75 cm. Surface smooth and weatherworn. Longitudinal pitting 
as in all the weathered eggs. A few small nodules. No remains of chalky covering.
