 (1S33) ; but the measuivments given in the original description clearly show 

 that the author hud the large form before him. This is found in various parts 

 of Ecuador, and I believe that Bogoti skins would also belong to this large form, 

 Prioni/7i)/nc/i</s jjlat;/rlii)nchiis jAat>/rh>/nrlii(s :'Li iulli. ). or they may be intermediate. 

 All those from Panama, however, are very mnch smaller, and the back aud abdomen 

 are slightly more tinged with yellow. The average measurements are : —

Two males, Pariiniba, :i;")nii feet. "Iris dark brown (greenish brown), bare 

 skin round eye green ; feet greenish bine, soles yellowish white ; base of maxilla 

 below diagonal Hue aud mandible reddish brown (chocolate-brown)."' (Sic .') 



184. " Rhamphastos ambigiius Sw." 



Two otiicr skins from Paramba have shorter wings, and (in skin) the base 

 of ma.xilla and mandible look almost black, while in the two specimens mentioned 

 above these jiarts look more or less reddish. These latter would be R. tocard, 

 while the two smaller ones would have to be called, according to museum usage, 

 R. amhiguHS. Mr. Rosenberg calls the mandible and base of maxilla of one of 

 them dark chocolate, of the other dark brown ; bnt neither does he call these 

 parts of the bill black, nor those of the former supposed species red. 



1 do not for a moment believe that they are two species, but the diflForence in 

 size rei[uires attciition. The same sexes, however, must be compared, as i\ie female 

 is always considerably smaller than the male, and especially the bills dififer much 

 in size, a jieculiarity not mentioned in the Cat. B. Brit. Mies. XIX. p. 127. 



Since these lines were written we have received some more skins from Paramba, 

 and again we find the same phenomenon ; bnt in one the base of the bill is cjuilc 

 intermediate in coloiu-, and the wing shorter. 



185. Pteroglossus sanguineus Gould. 



Cachavi and Paramba, ouu to 3uimi feet. In both sexes is the "iris yellow; 

 feet green." Mandible black, with a narrow white border at base. The three birds 

 sent are undoubtedly typical P. sanguineus, and not P. erythropygia.
