Vienna from North Africa, and will therefore be that of O. nubicus 

 (H, Smith ; Bp. Consp. p. 10), if that species is really distinct from 

 the southern O. cmricularis. The long diameter of this egg is 3'9, 

 the short diameter 2'8 inches. 



The egg of the Parson-bird or Tui, Prosthemadera novce seelandice 

 (Gm.), was taken in New Zealand in 1852 by Dr. White. Its colour- 

 ing is somewhat different from that of the other Honey-eaters with 

 which we are acquainted, not presenting the usual rich red ground- 

 colour which is the general characteristic of the eggs of that family 

 of birds. The long diameter of this egg is TO, the short diameter 

 0'75 inch. — Proc. Zool. Sac.
