The Secretary reported that a male Giraffe had been fawned in the 
menagerie on the previous day. The produce of the mother, who 
was imported in 1836, thus amounted to five males, all of whom, 
with one exception, were in full health and vigour. The dates of 
their birth are as follow :— 
1. June 9, 1839; died soon after. 
2. May 24, 1841; now in possession of the Zool. Soc. Dublin. 
3. February 25, 1844; now in the Menagerie.

The Secretary also stated that the Menagerie had been enriched, 
since the last meeting, by a fine specimen of the Tui Bird (Prosthe- 
madera Nove Seelandi), brought from New Zealand by Lieut.Gough, 
R.N. This gentleman had also succeeded in conveying to England an 
example of Platycercus tabuensis, Latham, from the Feejee Islands, 
which unfortunately died before it reached London. The skin had 
been mounted and was exhibited to the meeting.

This is the largest species of this genus we remember to have seen ; 
for which reason we have named it 7. principalis. It is of a some- 
what triangular form, rounded at the angles, and rather compressed, 
not being nearly so globular as the remaining three species. The 
substance of the shell is rather thin, it is smooth and of a pale colour 
with several brown transverse lines disposed in pairs; the spire is. ©

second are small and very dark-coloured, the third and fourth are
