Feet inunense- ly larg(! and strong, roughly granular-retic- ulate; tarsi little feath- ered above in front; toes all free to the liase, the outer versa- tile. Claws very large, all of equal lengtlis, or taper- ing terete, not being scooped out under- neath, but all compressed, and the middle one sharply grooved on the inner face. I?ill tooth- less, contracted at the cere, elsewhere inflated, with very large hook; gonys convex, ascending; nostrils oval, oblique, without tubercle, and in tlie edge of the cere. The peculiarities of the plumage and of the feet are in evident adaptation to the senii-aqnatic piscivorous ha1)its of these "fishing hawks," which require a water-jtroof covering, and great talons to grasj) their slippery quarry. The structural characters arc rather those of the buteonine than the falconine birds of prey, in the coracoid aiTangement, etc. The supraorldtal shield is rndiinentary, leaving the eye flush with tlic side of the head. The family consists of a single genus, and probably but one cosmopolitan species, the well-known Os[)rey, Pamliov lutliaetits. PAXDl'ON. (Or. TlavSiiav, Lat. Pmidion, noui. propr.
