TWO NEW SUBSPECIES OF BIRDS FROM THE SLOPES 



OF MOUNT PIRRI. EASTERN PANAMA 1 



By E. W. NELSON 



The two subspecies described below were part of the rich o 

 tion made by E. A. Goldman in Eastern Panama, during- the seasi n 

 of 1912, while engaged in the Smithsonian Biological Survey of 

 Panama. Other new birds from this collection were described in a 

 recent paper. 2 



The present subspecies are additional evidence that the fauna of 

 Mount Pirri is more closely related to that of South America than 

 to that of the Canal Zone 



CAPITO MACULICORONATUS PIRRENSIS, new subspecies 

 Mount Pirri Bavbet 



Type. — No. 238116. adult male, U. S. National Museum (Bio- 

 logical Survey Collection) from Cana (1,800 feet alt.), at base of 

 Mount Pirri, Eastern Panama; collected April 11, 1912, by E. A. 

 Goldman. (Original number 15468.) 



Distribution. — Known only from type locality. 



SubspeciHc characters- -Colors closely similar to those of 

 C. 111. rubrilateralis Chapman, from Cauca, Colombia (Bull. Am. 

 Mus. Xat. Hist., vol. 31, p. 144, July 23, 1912), including the brigh! 

 red side-patches, but the breast patch is a deeper and more oral 

 \ ellow as in typical maculicoronatus. The measurements also agree 

 with those of the tvpical form in being distinctly less than in 

 rubrilateralis. 



Measurements of type. — Wing, 81 millimeters; tail, 44; culmen, 

 2\ ; tarsus, 20. 



Remarks. — The present form cannot well be referred to either 

 typical maculicoronatus or to rubrilateralis, since it has the coloi of 

 the latter and the size of the former. Its range is intermediate 

 between those of its two relatives, and it is thus an intergrading 

 form which appears worthy of recognition. 



PSEUDOTRICCUS PELZELNI BERLEPSCHI, new subspecies 

 Px.-rlepsc.il Flycatcher 

 Type. — No. 238137. adult male, U. S. National Museum (Bio- 

 logical Survey Collection), from Mount Pirri, Eastern Panama; 

 collected April 2^. 1912, by E. A. Goldman. (( Iriginal No. [5578. 1
