these birds were taken at Camp La Vaca and six at Camp 
Pital. This species may be considered the most constant 
and the most numerous of the Mallophaga found in tina- 
mou in Western Panama. 
Goniodes laticeps Piaget. A few specimens in various 
stages of development were found on five out of eight tina- 
mous, Tinamus major castaneiceps Salvadori, that were 
examined. 
Goniodes minutes Carriker. Several specimens were 
collected from each of two tinamous, Tinamus major cas- 
taneiceps Salvadori. 
Goniodes spinosus Piaget. A number of males and fe- 
males of this species were taken from two tinamous, Tin- 
amus major castaneiceps Salvadori, at Camp La Vaca. 
Kelloggia brevipes Carriker. Taken in considerable 
numbers from each of eight tinamous, Tinamus major cas- 
taneiceps Salvadori, examined. 
Omicholax robustus Carriker. Present in small num- 
bers on each of six tinamous, Tinamus major castaneiceps 
Salvadori, examined. 
Philopterus cancellosus Carriker. Several males and fe- 
males were collected from a Swainson’s toucan, Rhamphas- 
tos swainsonii Gould. 
Degeeriella francisi Carriker. This species was repre- 
sented by six specimens taken from a Wagler’s oropendula, 
Zarhynchus wagleri wagleri (Gray), at Camp Pital. 
Esthiopterum assesor Giebel. This appears to be the pre- 
dominating species of Mallophaga found upon the black 
vultures, Catharista urubu (Vieillot). Four of these birds 
were examined at Camp Pital and each yielded many 
specimens. 
Esthiopterum columbae Linnseus. One specimen was 
found on a Cassin’s dove, Leptotila cassini cassini (Law- 
rence), at Camp Pital. 
Esthiopterum tinami Carriker. One female of this 
species was taken from a tinamou, Tinamus major castane- 
iceps Salvadori.
