Marcajiata, 8.E. Peru, 2500 ft., March 13,

10 mm. 



This rare bird cannot be referred to the genns Cajisii'iiipi.i, but appears to be 

 most nearly related to certain species of otlier genera, notably Li'ptopogon poecilotis 

 Scl. and I'ogonotriccus vene.zuelanns, as has already been suggested in another 

 connection.* In structure these three species are very much alike, having extremely 

 slender legs and feet, the tarsus covered with a single fused lamina, the rectrices 

 pointed at the tip, etc. C. orhittdis and P. reiu\::ui'lanus agree perfectly in the 

 shape of the bill, while L. poecilotis has the culmen slightly more rounded above, 

 not distinctly ridged. The style of coloration is also very similar, the chief 

 characteristics being the slaty cap, abruptly contrasted with the green back, the 

 double-bar across the wing, the yellow under surface, and the pale lower mandible. 



L. poi'cilot/s may, however, be recognised by its deep ochreous (instead of 

 sulphur-yellow) wing-bands and whitisli (not yellow) chin, besides some minor 

 differences. 



C. orbitalis shares the sulphur-yellow wing-bauds with P. V('i)e.:uelaiius, but 

 differs in various important points. The crown is darker, sl.aty grey (not cinereous) ; 

 the back deep olive-green (instead of light grass-green) ; the under parts are deeper 

 yellow, and washed with greenish on sides of throat, cheeks, and chest (which is 

 not the case in P. temxuelanihi) ; the legs and feet dusky brown (instead of 

 yellowish flesh-colour) ; the large, semilunar black patch on the posterior ear- 

 coverts, so conspicuous a feature in both L. poecilotis and P. cenezuelanus, is 

 scarcely indicated by a few small dnsky olive spots. 



The female from S. Gaban lately received at the Munich Museum appears to 

 agree in coloration with the type, but is considerably smaller, this difference being 

 evidently sexual. 



It is difficult to determine to which genus the three species just dealt with should 

 be assigned. They are nndonbtedly out of place in the genus Leptopogon, which 

 has a much more rounded, elongated bill, stronger feet, etc., but the}' are no typical 

 Pogonotriccus either. Although I feel sure that they will ultimately have to be 

 separated generically, I am unwilling to do so without a thorough revision of all 

 the related groups of this family.

The type-specimen is in rather ])oor condition, the under parts being stained 

 and discoloured, yet there can be no donbt that it belongs to M. p. pulcher, and not 

 to its ("olombian representative .1/. pulcher bellus Scl.,t as sujjposed by the late 

 P. L. Sclater. {
