2 Contopus brachytarsus, Sclater, Cat. Am. B. 1862, 231. {Empidonax brachyt. ScL. Ibis, 

 1859, p. 441.) A strongly marked race, but distinguishable from schotti only by just apprecia- 

 ble differences in color (being paler beneath), and shorter wing and bill, the latter broader at 

 the tip. 



3 Contopus {brach,tarsus var. ?), var. schotti, Lawu. Ann. N. Y. Lye. IX, 1869, 202 (Yucatan). 

 Very nearly related to G. richardsoni, but easily distinguished by the very different proportions.'
