To some of the Linnaean genera he dare not, however, assign a place, for instance, Buceros, Haematopus, Merops, Glareola (B risson's genus, by the by) and Palamedea.
The Oyster-catcher of Europe is the Haematopus 2 ostralegus or Linnaeus, belonging to the group now called Limicolae, and is generally included in the family Charadriidae; though some writers have placed it in one of its own, Haematopodidae, chiefly on account of its peculiar bill - a long thin wedge, ending in a vertical edge.
Differing from this species in the possession of a longer bill, in having much less white on its back, in the paler colour of its mantle, and in a few other points, is the ordinary American species, with at least three races, Haematopus palliates.
