1190 MR. C. E. HELLMAYR ON THE 



This series, which belongs to the Tring Museum, enahles us 

 at last to make out the status of P. granadensis, originally based 

 upon an adult female from the same district (Cali). I am sorry 

 to say that Mr. Bangs under P. canus simply redescribed the 

 true granaclensis. This is quite evident on comparing the two 

 descriptions, which agree almost word for word. In a note 

 appended to the diagnosis of P. o. harterti *, I have already 

 alluded to the distinguishing characters of P. o. granaclensis, but 

 a few additional remarks may not be out of place here. The 

 geographical vaiiation of this group was quite unsatisfactorily 

 understood until Mr. Hartert t pointed out the differences 

 existing between the three races then known to him. Hartert 

 was, however, not acquainted with granaclensis Lafr., for the 

 birds from Western Ecuador to which he applied that name proved . 

 to be distinct and were subsequently separated by me as P. o. 

 harterti. 



According to our present knowledge, the following subspecies 

 of P. olivacetos are easily recognizable :■ — 



(a) P. OLivACEus OLIVACEUS Lafr. 



Type from Bogota. 



Adult. Back warm greenish bi^own or olivaceus brown ; chest 

 strongly tinged with deep olivaceous ; breast and abdomen 

 yellowish with well-defined, though narrow, dusky stripes, 

 particularly on the lower bi-east and flanks ; quills edged with 

 olivaceous. Adult males with tijDS to feathers of forehead 

 " flame scarlet" (rather duller than pi. vii. fig. 14 of Ridgway's 

 Nomenclature). 



Hab. Apparently the Eastern Cordillera of Colombia. All the 

 specimens I have seen, eleven at Tring, and nine in the Munich 

 Museum, are of the well-known Bogota form. 



(6) P. OLIVACEUS FLAVOTINCTUS RidgW.J 



Type from Pozo Azul, Western Costa Rica. 



Adidt. Back not unlike P. o. olivctceios, but mostly somewhat 

 darker ; edges of remiges brighter and deeper olivaceous yellow ; 

 chest decidedly darker, more brownish, less greenish; dusky 

 strijies of breast and abdomen wider and less sharply defined. 

 Adult males with tips to feathers of foi'ehead dull " cadmium 

 orange" (Ridgw. Nomencl. pi. vi. fig. 2.) 



Hah. South-western Costa Rica (south of Pozo Azul de Pirris) 

 and Chiriqui §.

 V\'. Costa Rica). 



§ An additional subspecies, P. olivaceus panamensis Eidg-w. (Proc. Piol. Soc. 

 Wash. xxiv. 1911, p. 34: Lion Hill Station, Panama) inhabits Panama (Lion Hill, 

 Tocoume). There is a single adult male from tlie latter locality, obtained 

 by E. Andre, in the Tring Museum. This form is nearest to P. o.Jfavotincttts, but 

 has the chest buffy yellow (instead of brownish) and the back much paler, light 

 earthy-brown.
