De Lafresnaye has given an account of the species of this peculiar 
South American genus of Tyrants in the ‘ Revue Zoologique’ for 
1846, p. 360. Bonaparte in his ‘Conspectus’ has rather extended 
the list; but his 4th and 5th species from Desmarest seem rather 
doubtful, and the Muscicapa diops of Temminck is, I believe, quite 
incorrectly stated to be identical with Hartlaub’s Todirostrum grana- 
dense, and does not belong to this genus. There is also little doubt 
that Todus melanocephalus, Spix, is the same as Todus cinereus, 
Linn., and the first and third species of the Conspectus are therefore 
coequal. The latest additions to this genus are :— 
1. T. ruficeps, Kp. in these Proceedings, 1851, p. 52=T7. multi- 
color, Strickl. Cont. Orn. 1852, pl. 85. fig. 2.—(Todirostrum pecto- 
rale, Kp.of the same page does not differ from Hartlaub’s granadense.) 
2. T. chrysocrotaphum, Strick]. Cont. Orn. 1850, p- 48. pl. 49. 
3. T. striaticolle, Lafr. Rev. et Mag. de Zool. 1853, p. 58. 
4. T. fumifrons, Hart]. Journ. f. Orn. 1853, p. 35; and 
9. T. rufilatum, Hartl. l. c. 1855, p. 98. 
The present elegant species I cannot identify with any of those 
previously described. It is a typical Todirostrum, and may be placed 
near 7’. cinereum, the type of the genus, from which it is easily 
distinguished by its pure black head, yellowish-olive back, and white 
throat. I obtained the only example of it I have yet seen from the 
MM. Verreaux, by whom it was received along with many other 
rare and valuable species from Santa Martha, on the north coast of 
New Grenada. ; 
Mr. Gould has specimens of the Todirostrum spiciferum, Lafr. 
(Aves, Pl. LXXXIV. fig. 2), from Chamicurros in North-east Peru. 
This species, with its largely-developed crest, quite reminds one of 
the Muscivora regia (Gm.).
