on record. 
Red-breasted Merganser, M. serratw ; generally a winter visitor. 
Groosander, M. merganser ; sometimes obsei’ved in Mount’ s-bay, 
but only in winter plumage : the adult male has the breast 
of a beautiful glowing maroon buff colour. 
Great Crested Grebe, Podiceps cristatus ; not uncommon in winter 
on marshes. 
Red-necked Grebe, P. rnlricollis •, quite as often occurring as the 
last-named species, — frequenting the same localities. 
Horned Grebe, P. cornutus ; specimens not in adult pluma 
occasionally obtained from the Land’s-end district. • 
Eared Grebe, P. auritus ; specimens not unfrequently obtained, 
but generally in immature plumage : a specimen in adult 
summer phimago obtained some years since from St. Just 
pool, Falmouth harbour, and now in the Truro museum. 
Eittle Grebe, P. minor ; the most commonly distributed of all the 
grebes in the Land’s-end district. In summer plumage the

numbers every year, generally in immature plumage, and in

in the adult state have been killed. 
Black-throated Diver, C. arotious ; more rare than the former 
species, sometimes SQen in Mount’s-bay. 
Red-throated Diver, C. septentrionalis ; common in the autumnal 
and winter months in Mount’s Bay, and at this season 
invariably found without the red throat, and in the plumage 
represented by Bewick as the “speckled diver.” 
Common Guillimot, Uria troih ; frequently seen singly, and in 
small parties, in Mount’s-bay, and around our coast. 
Ringed Guillimot, U. lacrgmans ; the specific distinction of this 
bird from the common guillimot is doubted.

wmll : one example, in intermediate plumage, taken some 
years since in Mount’s-bay. 
Eittle Auk, Mergulus melanoleucos ; not frequently met with on
