Nest, &c. ous molluscae. Its nest is said to be made upon the banks 

 of rivulets, under the cover of low bushes or tall herbage, 

 and its eggs, from ten to twelve in number, are stated to be 

 of a pure white, and not much larger than those of a pigeon. 

 During its summer migration it is found upon the coast, and 

 frequently in deep water, at a considerable distance from 

 land. It is to be regretted, that no author has described the

 a slight difference is observable, as compared with that of the 

 Golden-Eye, and the nostrils are placed nearer to the base, 

 shewing its connexion with the genus ffavelda,
