434 FEINGILLIDJE. 



short of the base of the middle claw ; inner toe entirely separated at the base from the 

 middle toe, and the outer with only the first phalanx united ; hallux about equal in length 

 to the lateral toes, but much stronger, its claw decidedly larger than that of the middle 

 toe. Wings decidedly longer than the tail, very concave beneath, the third, fourth, and, 

 fifth quills nearly equal and longest, the second a very little shorter, the first about 

 equal to the seventh. Tail about equal to the wing measured to the end of the 

 secondaries, nearly even or very slightly rounded, consisting of twelve rectrices, which 

 are acute, but not stiffened at the points ; the outer web of the median rectrices broader 

 at the base than the inner web. 



There is a small notch near the tip of the maxilla ; the rictal bristles are hardly 

 perceptible, and the posterior face of the tarsus on both sides is entirely undivided.

"Above dull olive-bro-wn, the back Trasbed with rusty; wings dusky, the middle and greater coverts tipped 

 with pale rusty, forming two distinct bands, the inner secondaries broadly edged with darker rusty ; 

 remaining secondaries narrowly skirted with dark umber-brown, the primaries with light dull ochraceous 

 or yellowish-olive. Tail dusky, the outer webs slightly greenish-olive. Pileum indistinctly streaked with 

 dusky ; sides of the head and neck dull olivaceous, lighter than the crown and nape ; chin and throat still 

 paler, the feathers pale only beneath the surface, the rest of the lower parts dull, light olivaceous, tinged 

 with deeper olive across the breast and along the sides. MaxiUa blackish, paler along the edge ; mandible 

 whitish ; legs and feet (in the dried skin) light brownish ; iris pale blue. Wing 2-5, tail 2'2, culmen 0*58,

1. Sporophila Othello, Bp. Consp. Av. i. p. 498. 



Major, nigerrimus, remigibus extus basi late albis, tectricibus inferioribus nigris.

This species is placed with S. crassirosfris in the section Coccoborus. The description 

 suggests Oryzohorus viuttingi {antea, p. 348), but the size of the wing-speculum does 

 not appear to correspond, and there are no dimensions given to guide our judgment. 



2. Oriturus mexicanus, Bp. Consp. Av. i. p. 469. 



TInicolor, uniformis. 



Hah. Mexico {Mus. Lugd.). 



Can this refer to Haplospiza uniformis (antea, p. 366)'? 



G. E. Gray places 0. mexicanus as a synonym of Hcemophila rufescens (Hand-1. ii. 

 p. 91, no. 7343) ; but this cannot be correct, the description corresponding in no way. 

 Two words of definition are not enough to give a species a proper status.
