t P . brunneus is, of course, not a synonym of simplex ( cf . F.B.I., 
2nd ed. vii, p, 87) but a distinct species : modestus Blyth is a nomen nudum 
but it refers to brunneus and not to simplex , 
3 We have never seen exact topotypes of P. b, zafhaeus but we cannot 
separate Bornean birds which are said by Oberholser to be eaphaens.
