To the straight-billed humming-birds, which the French Zoologists name 

 Oiseaux mouches, belong a still greater number of species than to the 

 preceding division. The bill is of very various lengths in some even 

 shorter than the head, and awl-shaped, as Ornismya Lindenii PABZUDAKI, 

 GUEB. Revue et Mag. de Zool. 1849, ?1 - 8 > Oxypogon Lindenii GOULD 1. L 

 PL 13; Ornismya microrhyncha BOISSONNEAU, GUEB. Magas. de Zool. 

 1840, Ois. PL 16; in most longer than the head, as, Trochilus sparganurus 

 SHAW, Omismya Sappho LESS. Ois. mouch. PL 27, 28, Cometes sparganu- 

 rus GOULD 1. 1. PL 47 ; in some as long even as the whole body, Trochilus 

 ensiferus, Ornismya ensifera BOISSONN., GUEB. Magas. de Zool. 1840, 

 Ois. PL 15, Docimastes ensiferus GOULD L 1. PL 7. Here the bill is 

 in some degree bent upwards; such is more decidedly the case in other 

 species, of which the bill is less elongated, as Trochilus recurvirostris, 

 Campylopterus recurvirostris SWAINS., LESS. Ois. mouch. PL 37, Colibr., 

 Ois. m., Suppl. PL 34. and Trochilus avocetta LESS. Colibr., Ois. m., Suppl.
