The Slavonian grebe (P. auritus, L.) is much more

 each other both in size and colouring-; but may be dis-

Cormorants. 



The weights of two of the above-cited eared grebes were 

 i of oz. and ill oz., while those of a series of Slavonians 

 range from 1 1 1 to 1 3} oz. 



The Great Crested grebe is a much larger bird, a 

 female shot February 3rd, 1881, weighing 31 oz., while a 

 male, obtained two years later, scaled 32I oz. Both these 

 had been feeding on small fish ; while the gullet of a 

 Red-necked grebe (P. g'riseig'end), shot at the same 

 season, was crammed with shrimps. The latter species 

 is rather less common and weighs 18 to 19 oz.
