CATHARUS FUSCATER HELLMAYRI Berlepsch 



Catharus fuscater hellmayri Berlepsch, Orn. Monatsber., vol. 10, no. 5, May 1902, 

 p. 69. (Chiriqui.) 



Characters. — Gray of under surface, including sides and flanks, defi- 

 nitely darker; throat grayer. 



A juvenile in the Museum of Comparative Zoology from Coliblanco 

 de Sarapiqui, on Irazu, Costa Rica, taken August 23, 1899, has the 

 entire crown fuscous-black; hindneck natal brown; back, rump, scapu- 

 lars, and wing coverts between natal brown and bone brown, wings and 

 tail fuscous; throat and upper foreneck buffy brown, with the bases of 

 the feathers grayish white; sides of neck, breast, and area adjacent 

 olive-brown, with indistinct spots of dull chamois, and basal shaft 

 streaks of grayish white; flanks and undertail coverts olive-brown. 

 The culmen (in the dried skin) is fuscous; rest of the bill, tarsi, and 

 feet light brownish yellow, indicating that these areas were light- 

 colored in life, as they are in the adult bird. 



An adult male in the Museum of Comparative Zoology collected 

 above Boquete, Chiriqui, March 1, 1901, has the following color notes 

 on the label, made by W. W. Brown, Jr., "Iris white; orbital ring and 

 tarsus orange-vermilion; upper mandible vermilion, region of nostrils, 

 and tip of culmen dusky; under mandible vermilion." 



Measurements.— Males (10 from Chiriqui), wing 88.0-94.4 (89.7), 

 tail 64.6-73.6 (68.5), culmen from base 17.5-19.0 (18.2), tarsus 34.1- 

 36.8 (35.4) mm. 



Females (4 from Chiriqui), wing 78.6-81.9 (89.7), tail 54.0-60.4 

 (58.2), culmen from base 15.3-17.8 (16.5), tarsus 31.3-35.0 (33.4) 

 mm. 



Resident. Found in the mountains of Chiriqui, recorded on the 

 eastern face of the volcano above Boquete at 1200-3000 m, and in 

 eastern Chiriqui at Chame, and above Tole, including the upper valley 

 of the Rio Caldera (Bajo Mono). 



This race was known early in Panama, mainly from a series collected 

 in 1901 by W. W. Brown, Jr., on the mountain slopes above Boquete 

 (Bangs, Proc. New Engl. Zool. Club, vol. 3, 1902, p. 50). It may be 

 restricted in distribution, as I did not find it during several seasons on 

 the western and northern slopes of Volcan de Chiriqui, from above 

 El Hato and Cerro Punta to near Sereno on the Costa Rican boundary, 

 nor on the headwaters of the Rio Chiriqui Viejo. From eastern Chiri- 

 qui, Salvin (Proc. Zool. Soc. London, 1867, p. 132) received an early 

 specimen taken by Arce in the Cordillera de Tole, above Tole. 



Ridgely (in litt.) suggests that the restricted range may be based on
