148 BIRDS OF THE REPUBLIC OF PANAMA PART 3 



through eastern Honduras. To the south it continues beyond the 

 Panamanian border through western Colombia to western Ecuador, 

 and to the east across the Caribbean slope from the lower Rio Atrato, 

 through the departments of northern Antioquia and Cordoba. It 

 shows considerable individual variation in Panama, which in the male 

 is found mainly in the amount of gray on the forehead, and in the 

 extent of the black area on the back. On the Pacific slope, from 

 Cerro Azul to the Colombian border, most males are slightly paler 

 gray above. Females throughout show much variation from light to 

 dark, particularly on the lower surface. 



Salvin and Godman received specimens from McLeannan at Lion 

 Hill, and from Arce taken at Chepo, and it is on these that they 

 based their name, as they state in the original description, "Descr. 

 maris et feminae ex Panama. Mus. nostr." The action of Hellmayr 

 (Proc. Zool. Soc. London, 1911, p. 1158) in designating Panama 

 as the type locality actually was not required. 



In Colombia from extreme eastern Cordoba and the lower Mag- 

 dalena Valley through most of the Provinces of Magdalena and 

 western Guajira, there is a paler race, T. p. subcinereus Todd, in 

 which the male is lighter gray on the lower surface and on the side 

 of the head, and the female is lighter brown, both above and below.

P. L. Sclater (Cat. Birds Brit. Mus., vol. 15, 1890, p. 211) lists the 

 range of this species as "Hab. Panama, Colombia and Ecuador" with 

 no indication as to why Panama was included. As the three sub- 

 species now recognized are known only from the upper Tropical 

 and Subtropical zones of Colombia, the inclusion of Panama evi- 

 dently came through a lapsus calami. The same distribution found 

 in R. B. Sharpe (Handl. Gen. Spec. Birds, vol. 3, 1901, p. 16), ap- 

 parently came from the statement made by Sclater. There is no pres- 

 ent record for multistriatus nearer Panama than the northern end of 

 the central Andes near Valdivia, Antioquia.]
