gives a woodcut representing the bills of this species and C. pachyrhynchus respectively.* When 

 Mr. Grant becomes more familiar with Penguins, he will discover that the size and shape of the 

 bill is a very unsafe criterion as a specific character. A glance at the subjoined figures, 

 taken from two adult female specimens of C. pachyrhynchus in my collection, will sufficiently 

 demonstrate this. 



TWO HEADS OF CATARRHACTES PACHYRHYNCHUS- 



As Captain Hutton has pointed out to me by letter, my picture of " Penguins at home " 

 (vol. ii., p. 293) represents, in reality, a group of Gatarrhactes sclateri on the Bounty Islands, and 

 not C. pachyrhynchus. The Albatroses in the same illustration belong to Mr. Rothschild's new 

 species, Thalassigeron salvini. 



* "What Mr. Ogilvie Grant says is : " Although Sir Walter Buller first distinguished this species, he appears to 

 have overlooked the really important difference to be found in the shape of the bill and the wider white margin of the 

 wings." He says also : " The pale golden eyebrow-stripe commences immediately above the gape, but in some 

 specimens it is indistinctly continued towards the nasal opening, and is one of the least reliable characters." In 

 this Mr. Grant is quite at fault. The difference in the yellow facial streak is the great distinguishing feature between 

 the two species. So satisfied was Dr. Sclater that I was right in this respect that, without any reference to me, he gave 

 coloured drawings of the heads of both species (P.Z.S., February, 1889), in illustration of my paper, in order to bring out 

 this feature as distinctly as possible. Mr. Grant says further that I overlooked the broader white margin of the wing. 

 He is at fault again; for I stated the converse in my original description : " the posterior edge of the flippers, in its 

 middle portion, has a border of white nearly -25 of an inch in width, running off on both sides to a point." It is unfor- 

 tunate that the compiler of a portion of the British Museum ' Catalogue ' did not think it necessary to be more accurate.
