William Yarrell, Esq., Vice-President, in the Chair. 



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 amoimted 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. 



4. April 22, 1846; 



5. February 12, 1849; „ 



The Secretary also stated that the Menagerie had been enriched, 

 since the last meeting, by a fine specimen of the Tui Bird (Prosihe- 

 maderaNovcBSeelandice), 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. 



The papers communicated were —

 This is the largest species of this genus we remember to have seen ; 

 for which reason we have named it T. 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 

 rather elevated, consisting of five volutions, of which the first and 

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