PREFACE. IX 



Omitting these domestic animals, sixty-seven species of 

 British Mammals were treated of in the first edition. 

 Of these seven have now been rejected : namely, Vesper- 

 tilio emarffinatus and Phoca barbata as having been wrongly 

 identified, and Vesp. pygmceus, Plecotus brevimanus, Sorex 

 remifer, Lepus hibernicus, and Physeter tursio as not being 

 certainly distinct species. 



On the other hand, thirteen species have been added to 

 the list, of which one only is a land animal (Sorex pyg- 

 nuBUs)*, two are Seals {Phoca hispida and Cystophora 

 cristata), and the remaining ten are all Cetaceans, These 

 last are : — Balmna biscayensis, Megaptera longimana, 

 Balanoptera sibbaldii, B. laticeps, B. rostrata, Hyperoodon 

 latifrons, Ziphius cavirostris, Grampus griseus, Delphinus 

 acutus, and D. albirostris. 



The whole catalogue of British Quadrupeds, as 

 accepted in the present edition, includes seventy-three 

 species, belonging to the following orders : — 



The claims of three of these species to a place in our 

 Fauna must, however, be regarded as somewhat doubtful ; 

 these are Vespertilio murinus, Phoca grcenlandica, and 

 Balmna mysticetus. The reasons for and against their 

 admission are treated of under their separate heads. 



* Sorex pygmceus was at first accidentally omitted, and the error was not 

 detected until the portion of the work treating of the Insectivora had been 

 printed off. A figure and description have heen given on a single leaf, with 

 the pagination " 148a," so that it may he bound in at its proper place.
