INTRODUCTION. 
CXXl 
Subfamily ANSERIN^E. 
In round numbers about thirty species of Geese are now known to ornithologists. They admit of being- 
divided into many genera, of which Cereopsis, Anser, and Nettapus are conspicuously distinct from each other ; 
it is, however, with the genera Anser Bernicla only, or true Geese, that we have to do with in the ‘ Birds 
of Great Britain.’
