No. 15,655, Mus. Smiths., mounted, adult, in nearty perfect plu- 

 mage, from the Auckland Is., U. S. Ex. Ex., T. R. Peale : type of 

 Apt. Jfavilarvata Peale, I. c; basis of Cass. I. c. There are no 

 true lateral crests as in the typical species of Eudyptes, but all the 

 feathers of the face, and most of those of the crown, are length- 

 ened and linear. The yellow of the cheeks and crown has a dull 

 soiled shade, and that of the crown is sharply streaked with fine 

 black lines, one on each feather ; the unlengthened feathers of the 

 hind head, and those over the auriculars and through the e}-es, 

 form a well-marked band of much brighter and purer sulphur 3-el- 

 low ; the lower parts of the head, and uppermost of the neck, 

 including the throat, have a peculiar brownish cast ; and, alto- 

 gether, the head markings are unique in the family. The under 

 parts are white, up to the slight gular brownish just mentioned; 

 the upper parts are of a pale watery blue, more dilute than on an 

 average among the other species. The head markings, and length- 

 ened feathers of the vertex, together with the points of form here 

 to follow, show how the species is a link between true Spheniscus 

 and t} T pical Eudyptes. Bill stoutish, straight, tip fairly hooked, 

 but under mandible hardly truncate, nasal sulcus as usual. The 

 antise run out pointedly, about ^ of an inch be3 r ond base of cul- 

 men, but still do not conceal the nostrils ; from their apices, the 

 feathers rapidty retreat, to angle of the mouth, leaving the maxil- 

 lar tomia entirely bare, while those on the under mandible simi- 

 larly expose the whole tomia, although between the rami they 

 reach within less than an inch of the end of the bill. Chord of 

 culmen 2.10 ; depth of bill .85 ; antiae to tip 1.75 ; gape 3.00 : the 

 anterior canthus is just over the angle of the mouth. Tail very 

 short (under 2 inches), and much rounded, as in Spheniscus de- 

 mersus or minor. The whole length of the bird is somewhat over 

 2 feet.
