to the tips, with a narrow edging only of reddish, instead, as in both the other species, of 

 having the entire inner wehs of most of these feathers light cinnamon. The bill is shaped as 

 in crinii%s, but the edges are slightly convex instead of straight ; it is broader than in mexi- 

 canus. 



It is probable that the male of this species is somewhat differently colored froro the female 

 described above. 



It is not irnprobable that this bird may belong to the genus Blacicws of Cabanis (Journal fiir 



Ornithologie III, Nov. 1855, 480,) characterized as having the wings shorter than in Myiar- 



ckus ; the bill much depressed, flat, and broad ; the tail somewhat emarginated. In this event, 



and should the genus be considered worthy of retention, the present speciei^ will be called 



Blacicus lazvrencii. 



List of specimens.

Ch.— rHeetd with a blended depressed moderate crest. Tarsus decidedly longer than middle toe, which is sca^c^Iy longer 

 than the hind toe. Bill rather narrow ; width at base about half the culmen. Tail broad, long, slightly forked ; equal to the 

 wings, which are moderately pointed, and reach to the middle of the tail. First primary shorter than the sixth. 



This genus agrees with the preceding in the length of the broad tail, but has a longer tarsus 

 and a different style of coloration. The species are distinguished as follows : 



Sooty black ; belly and edge of the tail pure white S, nigricans. 



Brownish olive above; crown darker ; beneath and edge of tail jellowish.. S.fuscus, 



Grayish brown ; belly reddish cinnamon S. sayus. 



This genus I first find referred to by Bonaparte in tlxe notice of Delattres' collections, in 

 Comptes rendus, 1854, where he names Sayornis nigricans. I am, however, inclined to believes 

 that he has given a conspectus of the Tyrants in the Paris Ateneo italiano for 1854, and in it 

 this genus. 



Cabanis calls the supposed " Tyrannula fusca" of Cuba Aulanaa: fuscus, and claims the " T, 

 nigricans" as type if Bonaparte's name be untenable.
