Allied Species and Representative Forms.—P. philip- 
pensis, With the rufous extending over the chin and throat, 
ranges from China to the Malay Archipelago; P. capensis, 
with more white on the wings than in P. fluviatilis, inhabits 
Madagascar and Africa, also India and Ceylon; P. tricolor, 
closely allied to our bird, but showing more extensive rufous 
marking on the face, inhabits Borneo, New Guinea and many 
of the smaller Islands in the Malay Archipelago; P. nove- 
hollandie, a bird much about the size of P. fluviatilis, but 
differing in several details, inhabits Australia, Java, and New 
Guinea; P. dominicus, smaller than our bird, is found in the 
Southern States, Mexico, Central and South America as far 
as Patagonia. 
Note.—A specimen of the American Pied-billed Grebe, 
(Podilymbus podictpes), stated to have been procured near 
Weymecuth, in January, 1881, was exhibited by Dr. R. 
Bowdler Sharpe at the meeting of the Zoological Society of 
London, on June 21st, 1881. The bird was lhttle more than 
a nestling and still showed the long stripes on its neck. 
Mr. Saunders is of the opinion that it was probably an 
accidental exchange of specimens by the dealer, for he sold 
the bird as merely a Little Grebe.
