BRITISH BIRDS. 
253 
Latham enumerates fix fpecies and three varieties 
of this genus, five of which are accounted Britifli 
birds. George Strickland, Efq. of Ripon, to whom 
this work is much indebted for fundry communi- 
cations, enumerates fix fpecies of this genus, which 
are all met with in Great Britain and its adjacent 
ifles : the author agrees with him likewife in opi- 
nion, that much remains to be done in order to 
clear up the doubts in which their hiftory is in- 
volved, and by which the clafsification of the dif- 
ferent fpecies is confufed : he fays — The genus 
Mergus, though only a very fmall tribe of birds, 
ftill remains in the greateft obfcurity, and I have 
not yet met with any ornithologift who has not, in 
my opinion, multiplied the number of the fpecies, 
by confidering birds of this genus as of diiferent 
kinds, when they differed only in fex,’’ His ar- 
rangement is as follows : — 
Genus Meegus. 
Merganfer . . . Goofander. 
Cqftor Dun-Diver. 
Serrator ..... Lefs Dun-Diver. 
Albellus Smew. 
..... Lough-Diver. 
Minuius .... Red-headed Smew.
