Ventral aspect. A belt of white across the breast until it 

 touches the wing, and separated from the white of the head by 

 a ring of black about half an inch broad ; remainder of breast 

 black, quickly changing to blackish, which itself changes to brown 

 on the abdomen and under wing coverts ; the flanks, like the 

 lower part of the breast, are shining black. 



Length, from tip of bill to apex of tail, 20j inches ; alar ex- 

 panse 27^ inches ; the two first primaries longest and subequal. 



A specimen of this beautiful duck, the first which I have seen, 

 was shot in the bay of Laprairie this spring (1862) by a habitantj 

 and was purchased by Mr. Thompson of this city, who has kindly 

 placed it at my disposal for examination, I believe it to be one 

 of the rarest of our visitants of this species, and to demonstrate 

 that an acquaintance with our Fauna must be a work of many 

 years.
