On the western side of the lower Atrato Valley and north at least to the 

 Panama R. R., it is replaced by C. I. mentalis Cass. 



I have seen no Peruvian specimens of this species. Should the south- 

 west Colombian bird prove to be different it would doubtless stand as Celeus 

 loricatus fraseri (Malh.) described from Babahoyo, w. Ecuador.

(1751a) Celeus loricatus mentalis Cass. 



Celeus mentalis Cass., Proc. Acad. N. S. Phila., 1860, p. 137 (Turbo; R. 

 Atrato; type in Nat. Mus., examined). 



Celeus squamatus Lawr., Ibis, 1863, p. 184 (Lion Hill, Panama; type in Am. 

 Mus., examined). 



Inhabits eastern Panama from at least the Canal Zone eastward to the 

 western side of the lower Atrato Valley. 



Comparison of Cassin's type, a female in the National Museum, and nine 

 specimens from eastern Panama (Cana, Marraganti, Chepigana, El Real, 

 Tapaliza, Boca de Cupe) with our eight specimens of loricatus, shows that 

 mentalis is a strongly marked form which may be distinguished from the 

 more southern race by the almost entire absence of bars on the back and 

 inner wing-quills, the smaller black area in the feathers of the crown, more 

 ochraceous underparts on which the black markings are narrower and a 

 more extensive ochraceous-tawny area on the throat, which in the male 

 separates the black markings of the breast from the red of the upper 

 throat. 



Examination of Lawrence's type of Celeus squamatus shows that it is 

 referable to this form.

 Picus rubricoUis Bodd., Tabl. PI. Enl., 1783, p. 37 (Cayenne). 



A female from La Morelia differs from two from British Guiana in hav- 

 ing the outer webs of the inner primaries rufous from a point just beyond 

 the primary coverts to their base. A small amount of rufous is therefore visi- 

 ble in the closed wing, and the bird thus shows some approach toward C. 

 trachelopyrus.
