the present collections in England, there can be no doubt 

 that the whole six species of the genus Phasianus may be 

 treated in the same manner as soon as a sufficient number 

 of pairs can be obtained. 



The number of Species of Vertebrate Animals 

 at present possessed by the Society is upwards of 500, 

 exclusive of Fish, Zoophytes, and MoUusca, of which alone 

 upwards of 300 species have been exhibited since the 

 opening of the Aquavivarium.

These are represented by an aggregate number of 1145 

 specimens. 



The Collection of Fish, Zoophytes, and Mollusca, has 

 fully maintained the interest which it excited from the 

 first. 



The numerical extent of this collection continues to be 

 as great as the size of the tanks will admit ; and the perfect 

 success of the system pursued with the animals is satisfac- 

 torily demonstrated by the fact, that several specimens are 

 still existing which were originally placed there, and that 

 many of the Zoophytes are reproducing in great numbers. 

 The various stages through which some of these forms pass 

 to their final development, are thus subjected to observa- 

 tion in the most interesting manner, and an accurate record 

 of the result will be kept by means of drawings made with 

 the assistance of the microscope by Mr. Jennens.
