BANGS AND PENARD: NOTES ON AMERICAN BIRDS. 373 



CoMETORNis, gen. nov. 



Type. — Todirostrum .sqiiamaccrista Lafresnaye, Rev. zool., 184G, 

 p. 363. 



Generic characters. — (See Ridgway, Bull. 50, 1'. S. N. M., 1907, 

 pt. 4, p. 369, under Lophotriccus). 



The specimen, Lafr. coll. 4,632, listed by Verreaux as one of the 

 types of T. spicifcrum, has a label, in Verreaux's handwriting, and is 

 marked as ha\-ing come from Peru instead of Brazil. This specimen 

 does not agree with the description, and there is nothing to support 

 Verreaux's statement that it is a type. It is, however, the bird to 

 which the name spicifcrum has been erroneously applied by authors. 

 We propose to call it 



CoMETORNIS VITIOSUS, sp. HOV. 



Type.— M. C. Z. 77,348, Lafr. coll. 4,632. "Perou" (Verreaux). 



Specific characters. — Differs from other species in this genus in having 

 the elongated crest-feathers edged with whitish instead of cinnamon or cinna- 

 mon-rufous. 



Description of type. — Top of head blackish, the elongated crest-feathers 

 edged with whitish; upper parts olive-green, wings and tail dusky, margined 

 with olive; wing-coverts and outer secondaries broadly tipped and edged with 

 yellowish green; under parts grayish, slightly striped, breast with dusky 

 markings; lower belly, sides and under tail-coverts pale greenish yellow. 



Measurements. — Type. Adult — wing, 51.0; tail, 37.5; tarsus, 

 15.0; exposed culmen, 11.0. 



Remarks. — We would have preferred a freshly collected specimen 

 for the type, rather than the old Lafresnaye specimen, but we have no 

 other. Fortunately it is in a good state of preservation. 



The species and subspecies of the new genus are : —
