. The cyclopædia of anatomy and physiology. Anatomy; Physiology; Zoology. 268 AVES. Fig. 118. This distinguished ornithologist proposes to divide the Tenuirvstrcs into the following families: Cinnyridtc, Sugar-eaters; Trochilidie, Humming-birds;—in which families the beak and feet are more remarkable for their tenuity and length : and Promeropide, Hoopoes; Me- liphagidte, Honey-suckers ; Nectariniade, Nec- tar-birds ;—in which the slenderness of the beak and feet is less remarkable. The Fissirostres, (jig. 118 J, like the Tenuirostres, are distinguished by a habit of feeding on the wing, but as their food, instead of Rostrum of the vegetable juices, consists of Caprimulgus. living insects, the form of the beak is modified accordingly, and is re- markable for its sliortness and the wideness of its gape, especially in the typical families. In these the mode of catching the prey is con- formable to their distinguishing characters ; they receive it in full flight into the cavity of their mouths, which remain open for that purpose, and where a viscous exudation within and a strong fence ofvibrissa on the exterior, assist in secur- ino- the victim. The longer-billed Fissirostres, on the other hand, seize their food by their bills. The following are the families of the Fissirostral tribe: Hirundinida;, Swallows; Cuprimnlgidte, Goat-suckers; these are characterized by the short, wide, and weak bill. Todidte, Todies ; Halcyonidte, King-fishers; eaters; these latter fa- mil ies are characterized by their stronger and longer bill, and fur- ther differ from the preceding in having the external toe nearly as long as the middle one to which it is united as far as the penultimate joint; they are therefore termed Syndactylcs by Cuvier.
