454 Mr. W. R. Ogilvie Graut on the 



female for the first time, and it may be briefly described as 

 follows : — 



Adult female. Like the female of D. dorsale, Sharpe, but 

 at once distinguished from this as from all the allied species 

 by having the rump bright yellow ; it further differs from 

 D. dorsale in having the breast and rest of underparts olive- 

 yellow, only a band down the middle of the breast and belly 

 beiug pure yellow. 



I observe that Messrs. Bourns and Worcester have sepa- 

 rated the Cehu example of the D. trigonostigma group from 

 D. dorsale, Sharpe, from Pauay. Having no series, but only 

 one male bird from each island, I do not presume to say 

 much on the subject, but the differences, even if constant, 

 are extremely slight. 



In the Museum collection there is also a male specimen 

 from Catbalogan, Samar, collected in March 1888 by Mr. E. 

 L. Moseley. This specimen appears to be perfectly similar 

 to our specimen of D. dorsale from Panay ; but possibly this 

 also can be regarded as a distinct species. It is certainly not 

 D. cinereigidare, to which Prof. Steere refers the specimen 

 that he obtained from Samar. If our friends in America 

 have a large series of these birds collected in Samar, they 

 may perhaps find that the bird from there is not D. cinerei- 

 gidare, but a distinct representative form. 



64. PlPRISOMA ^RUGINOSUM. 



Prionochilus aruginosus, Bourns & Worcester, Occ. Pap. 

 Minnesota Acad. Sci. i. no. 1, p. 20 (1891). 



A single male example, without doubt referable to this 

 species of Thick-billed Flower-pecker, was obtained by Mr. 

 Whitehead in the highlands of Lepanto. It should, however, 

 be referred to the genus Piprisoma, having nine primaries^ 

 the first reaching to the tip of the wing, the tail square, and 

 the nostril perfectly bare of hairs [see Oates, Fauna Brit. 

 India, Birds, ii. p. 375 (1890)]. The adult male specimen 

 before me agrees exactly Avith the description given of 

 Messrs. Bourns and Worcester's male type. Mr. Rothschild 

 has also recently obtained this bird from Mindoro.
