CAMARHYNCHUS INCERTUS Ridgway. 

 BUPFT OROTJITD FINCH. 



Adult male unknown; adult female similar to that of C. compres- 

 sirostris but smaller (the bill especially), with upper parts brighter 

 olivaceous and under parts distinctly yellowish buff; similar in colora- 

 tion to O. salvini, but much larger; wing, 63.50; tail, 38.10; culmen, 

 13.46;' tarsus, 20.83. 



Adult female. — Above bright buffy olive, the pileum rather dis- 

 tinctly streaked with grayish dusky, the back and scapulars more 

 obsoletely and broadly streaked or spotted with the same, entirely uni- 

 form posterior to the back, the color lighter and more distinctly huffy 



do not seem to warrant such procedure, as may be seen from the following, where 

 measurements of the type, and of females of C. psittaculus, together with those of C. 

 affinis, C. incertua, and C. pauper, all of which are recognized as species by the authors 

 named, are given for comparison: 



Locality. 



One female of C. peiltaculus from 

 Charles Island 



Three females of C. psittaculus from 

 James Island (average) 



One female of C. psittaculus from 

 Jervis Island 



One female (type) of C compressi- 

 rostris from Jervis Island 



One female (type) of C. incertus 

 from James Island - .

If two allied species {psittaculus and incertus) can occur together on James and 

 Duncan islands and also on Charles Island {psittaculus and pauper), I see no reason 

 why two {psiitandus and compressirostris) may not occur together on Jervis Island. 

 Without question the measurements of, the bill of C. compressirostris a,nd a Jervis Island 

 specimen of C. psittaculus differ much more than do those of the latter from the same 

 measurements of C. psittaculus from the different islands. According to the evidence 

 before me, therefore, I must continue to recognize C. compressirostris as a distinct 

 form until the contrary has been proven. 



^ Type now in the Tring Musuem. 



- Messrs. Rothschild and Hartert give the length of the culmen in three specimens 

 as 12-13 mm.
