 browner on the abdomen, and purplish-black on the throat, neck and rump, and 

 a similar line down the crown ; sides, bright rusty ; a metallic blue-black patch

 sides and crissum ; abdomen, dull white ; sides of face in front of the eye, 

 whitish, and a white patch on the ear-coverts. 



Very rare winter visitant. 



There are no records for the State except Turnbull's statement 

 (1869) that it is "a very rare visitant from the North to the sea- 

 shore." 



156 Camptorhynchus labradorius (Gmelin). 

 Labrador Duck. 



Adult male. Length, 18-23. Wing, 8.75. Middle and lower back and tail, 

 as well as a ring around the base of the neck, a stripe down the middle of the 

 crown and entire abdomen, black; sides of head, breast, scapulars and wing- 

 coverts, white. 



Female. Dull grayish-brown, with a white wing speculum. 



Young in first autumn. Similar to adult female, but with white showing 

 faintly on throat and breast. 



Extinct. Formerly a regular transient or winter visitant. 



Audubon (1838) says: "Along the coast of New Jersey it occurs 

 in greater or less numbers every year. It also at times enters the 

 Delaware River and ascends that stream at least as far as Philadel- 

 phia." Turnbull (1869) says: "Rare; a few are seen every season/' 

 which seems to be the last word we have on its occurrence in New 

 Jersey.
