NATURAL SCIENCES OF PHILADELPHIA. 209 



Diemen's Lund. Like No. 1338, but with more extensive patches 

 of gray down about the head, neck, and wings. 



No. 1339, Mus. Acad., Philada., from the Gould collection, 

 South Australia. Young, in downy plumage, grayish brown 

 above, white below. Bill one inch long. 



Nos. 1340, 1341, Mus. Acad., Philada., adults. Van Diemen's 

 Land, from the Gould collection ; types of S. undina. These spe- 

 cimens are slightly smaller than average minor, bluer than usual 

 but not bluer than No. 1338, for example, and with rather weak 

 bills. The chord of the culmen of No. 1341 is 1 inch, that of 

 1340 is 1.25, just as in No. 1338, and No. 15661. I cannot dis- 

 tinguish these specimens even as a variety. 



Hyatt reports another of the U. S. Ex. Ex. specimens in the 

 Boston Society's Museum, and one from the Coll. La Fresnaye ; 

 these, and several quoted by Gray and Schlegel, are all from the 

 one or another of the localities above mentioned, and to which 

 the species seems confined. 



We cannot discover, in Gould's undina, any specific characters. 

 The bird is one of the bluest of the penguins ; and the shade of 

 the plumage, as well as the hue of the bill and feet, varies with 

 age or other changeable circumstances.
