No. 15,661, Mus. Smiths., 9, adult, Boyauf I., N. Zealand, IT. S. 

 Ex. Ex., T. R. Peale. One of the types of Peale, op. cit. pp. 259, 

 335, No. 694, and of Cassin, op. cit. pp. 355, 450, No. 687. Stands, 

 as mounted, a foot high ; was probably 14 inches long ; wing 4.25 ; 

 tail 1.25; the rectrices scarcely surpassing the tectrices ; culmen 

 of bill, 1.25 ; gape, 1.75 ; from antioe to tip, only 1.00 ; depth of 

 bill at base, .45, its width there .25 ; tarsus .75 ; middle toe and 

 claw, 1.66. The feet are wholly reticulate with hexagonal plates ; 

 the hullux is completely lateral, the end of its nail barely touch- 

 ing the ground. The color of the feet is now undistinguishable; 

 but the webs and the toes towards their end appear to have been 

 darker than the rest. The bill is much shorter than the head, 

 slenderish, compressed, the hook of the maxilla bareby overarching 

 the end of the mandible ; the nostrils are entirely unfeathered, 

 and lie in a deep narrow sulcus that runs obliquely into the max- 

 illary tomium at the beginning of its decurvature ; the antioe are 

 acute, but only run out a little beyond the feathers on culmen, 

 falling short of the nostrils. Feathers occlude the interramal 

 space, and retreat in a straight line, obliquely upward and back- 

 ward, to the angle of the mouth. Thus the bill is most like that 

 of Spheniscus demersus in general characters, but somewhat ap- 

 proaches that of Pygoscelis. This is one of the only two penguins 

 that never gain a dark throat; the pictura is perfectly simple 

 blue above, white below; the line of demarcation passes straight 

 through the eye, shoulder, and thigh ; a spot at the end of the 

 under surface of the wing is blue, and the border of the wing is 

 white.
