Characters. In general structure the members of this genus are not unlike Neoswthora, 
but, besides being much larger, they have the tail proportionately longer and a differently 
shaped bill. The culmen is far more convex and in its apical portion strongly curved, the 
mesorhinium not flattened at all, being somewhat elevated and decidedly rounded; the sigmoid 
curve of the commissure rather more pronounced; the lower mandibleless high and notso swollen, 
with the gonys not abruptly ascending; the tip of the bill, though not acute, distinctly pointed, 
not blunt. In the wing the fifth, sixth and seventh primaries are the longest, the first primary 
somewhat more than half as long as the wing. Tail about four-fifths of the length of the 
wing, slightly rounded; the outermost rextrix being from to to 15 mm. shorter than the central 
one; the penultimate rectrix about 6 mm, longer, but a little shorter than the third and so on, 
Legs and feet relatively stronger than in Neoswthora, apparently more adapted to terrestrial 
habits. 
Coloration. Back and wings clear olive or pale rufescent brown, tail duller, more 
greyish. In one species (P. ruficeps) the top and sides of the head are bright ferruginous, in the 
other (P. gularis) the upper part of the head is ashy grey, with a well-defined black frontal- and 
superciliary stripe, while the lores, cheeks and ear coverts are white, more or less shaded with 
pale cinereous. Bill (in skin) bright yellow.
