Pulix affinis. 
Middlesex County, Mass. 
A flock of four cane into Fresh Pond this morning 
three of v/hich wore shot. They came in readily to a 
live Mallard decoy, but wore rather shy of a boat. 
Two cam© into Fresh Pond this morning and were shot. 
Twok one of tvro that came into Fresh Pond this morn¬ 
ing. I sculled within long range without much diffi¬ 
culty, and after shooting one the other v/ould not leave 
the pond, although it became exceedingly shy. They 
swam rather low in the v;ater frequently lying over on 
one side pluming themselves. The only noto^that I 
hoard from either of them was a low harsh croak . They 
rose vrith rather more ease than most “sea-ducks*, and 
when fairly on wing advanced with great swiftness. 
While flying the markings on the v/ings showed with great 
distinctness. 
An adult male killed on Fresh Pond. 
Shot tvm on Fresh Pond, both typical affinis . 
R.Deane started one from the ground in the hanlock 
grove bordering Fresh Pond, 
A male on the Assabet River, Concord, feedingamong 
some rushes. Ho was very tame and we paddled within 
ten yards of him before he v/ould fly. Ho sat very low 
in the water and as ho swam kept tv/itching his tail from 
side to side with groat rapidity. His head and neck 
looked proportionately large and thick. When he rose 
he trailed his feet along the surface for a few yards 
then raised them up behind extended back under his tail.
