PEEFACE TO THE FIFTH EDITION. 



THE first edition of this List was issued in 1862, and con-

 Gardens in the years 1864, 1865, and 1866.

The result is a nearly complete Catalogue of all the living 

 Vertebrates received by the Society during the past ten years.

 by death or departure were struck out ; but commencing from
