white, showing a distinct spot. As I have not before given 

 dimensions, I will do so now : — 



Fulix baeri (Radde) , 6 . Length 18*5 inches. Wing 8'25 ; 

 first quill 1 longer than second, and largest. Tail 3'0, of four- 

 teen stiff feathers, pointed, and nearly uniformly graduated, 

 outer -82 shorter than centrals. Wing falls 1*75 short of 

 tail-tip. Bill from forehead's protruding angle 1*45, to gape 

 2; uniform breadth '82. Small piece of tibia bare; tarse 

 1*48; middle toe and claw 2 - 45. In this specimen the head

 deep chestnut on each side of crown. 



Fulix baeri (Radde), ?. Length 17 # 5 inches. Wing 7'7 

 from flexure to tip, 1*2 longer than tertiaries, 1*5 short of 

 tail-tip. Tail 2*8, much graduated ; laterals - 9 shorter than 

 centrals ; under tail-coverts "95 shorter than tail-tip, upper 

 tail-coverts 1*1 shorter. Bill 155 to forehead, 2 to rictus; 

 height at base '78; breadth -90, a little narrower at base, and 

 darker in colour than in the male. Tibia bare at joint ; tarse 

 1*5 ; middle toe and claw 2*4. 



Head and neck blackish brown with dull reflections ; a 

 patch of reddish brown on each side at base of bill ; chin 

 white mottled with reddish brown. Breast yellower and 

 more diluted than in male, the colour not reaching down so 

 low. Flanks brown. The rest as in male, but duller. 



The commonest diving Duck in the market has been the 

 Crested Duck [Fulix cristata), then Baer's Duck, then the 

 Scaup [F. marila), and lastly the Golden-eye [Bucephala clan- 

 gula) . A few Velvet Scoters, CEdemiafusca, were offered. I 

 bought an adult male, and was surprised to find what a large 

 and hugely muscular stomach it had, containing bits of thick 

 bivalve shells. A Meretrix, one inch in width, was in its oeso- 

 phagus. I have not seen a single Black Duck, neither CE. 

 nigra, nor CE. americana. The latter is the species the Rus- 

 sians have sent me from the Aleutian Isles, though they call 

 it CE. nigra. They do not distinguish the two conspecies. 



The ordinary wild Ducks of the market have been the Mal- 

 lard, the Yellow-nib [A. zonorlajncha) , the Teal, the Shoveller, 

 the Pintail, the Widgeon, the Falcated Teal, and the Spectacle-
