FAMILY PIPRIDAE 34I 



around the large end, and scattered narrower lines, partly brown and 

 partly grayish brown on the lower half. It measures 15.1 X 21.1 mm. 

 Schonwetter (Handb. Ool., pt. 16, 1969, p. 129) lists two sets of two 

 from eastern Panama as 14.8-15.1x20.8-21.1 mm. In a set of two 

 of the related race Manacus vitellinus milleri of northwestern Co- 

 lombia, in the British Museum (Natural History), collected near 

 Remedios, Antioquia, by T. K. Salmon, one is elliptical in form, the 

 other long elliptical. In color, one is faintly buffy white, marked 

 heavily on the larger half with more or less confluent lines of cin- 

 namon-brown, in part verging toward chocolate and grayish brown. 

 The other tgg has these markings covering most of its surface, with 

 the basal color showing only in part. They measure 20.1 X 14.9 and 

 21.6x15.3 mm. 



MANACUS VITELLINUS CERRITUS Peters 



Manacus ccrritus Peters, Proc. New England Zool. Club, vol. 10, September 22, 

 1927, p. 9. (Almirante, Bocas del Toro, Panama.) 



Characters. — Male, with forepart of body and upper back yellow, 

 or only slightly orange ; lower surface more greenish yellow ; rump 

 and upper tail coverts brighter green. 



Female and immature male, darker green throughout. 



Measurements. — Males (10 from Bocas del Toro), wing 51.8- 

 55.0 (53.5), tail 31.2-36.8 (34.4), culmen from base 11.1-12.8 (11.9), 

 tarsus 20.0-22.6 (21.6) mm. 



Females (10 from Bocas del Toro), wing 52.9-56.3 (54.6), tail 

 32.1-35.7 (33.9). culmen from base 11.8-12.5 (12.1), tarsus 19.7- 

 21.4 (20.7) mm. 



Resident. Locally, fairly common in western Bocas del Toro, near 

 Changuinola and Almirante ; Isla Bastimentos. 



This interesting form was named by Peters from a series of eight 

 specimens collected by Hasso von Wedel near Almirante. Later this 

 collector secured others, part of them from Changuinola. In January 

 and February 1958, I found it frequently along the shores of the 

 southern arm of Bahia de Almirante on the slightly elevated land back 

 of the mangroves, and also along Quebrada Nigua, but in lesser 

 number. It was seen especially on the low elevations above the small 

 streams flowing into Ensenada de Ambrosio (the southern arm of 

 the bay) to the west of Isla Pastores. Among those who spoke 

 English the area was known as "Water Valley." Specimens in the 

 collections of the Gorgas Memorial Laboratory were taken during 

 banding operations near Almirante, on October 10 and November 12,
