, the more especially that this species, although not that inwhich it is exhibited in the highest degree of development or extension, isyet, as being one of the largest known, peculiarly well adapted for such anexamination. Two figures, therefore, are here introduced. In Fig. 1 are seen:—The upper and lower mandibles a b, the tongue c d,the terminal barbed portion c, the fleshy part d, the orbit and eye e, thesalivary gland f, the hyoid bones g g, the neck h h, the furcula i i, theoesophagus jj, the trachea k, its lateral muscles / /, the cleido-tracheal m m. In Fig. 2 are seen:—The lower mandible b, the salivary glands//^ thehyoid bones g g, the oesophagus j jj, the trachea k, the lateral muscles / /,the cleido-tracheal m m, the glosso-laryngeal n n, the muscles by which thetongue is exserted o o. The bill of this species, Fig. 1, a b, measures 3 inches and 2 twelfths fromthe angle of the mouth; and the tongue, c d, which lines in the broad groove 222 THE IVORY-BILLED WOODPECKER.

THE IVORY-BILLED WOODPECKER. 223 of the lower mandible, reaches to 2 twelfths of the extreme tip, but at thewill of the bird may be exserted so as to extend 3^ inches beyond the pointof the bill. The tongue itself presents the appearance of a slender fleshyworm-like body, having a middle longitudinal groove on its upper surface,which is transversely wrinkled, and terminated by a slender tapering bonypoint, of which the margins and part of the upper surface are covered withacicular prickles, which are in some degree moveable and directed back-wards, but not capable of being bent outwards, much less in the direction ofthe tip of the tongue. The length of this organ is apparently 2 inches 8twelfths; but if measured from the base of the basi-hyal bone, only 1 inch11 twelfths; its breadth at the base 2J twelfths, slightly tapering to the endof its fleshy part, where it somewhat suddenly contracts, so as to have abreadth of little more than 1 twelfth. The length of the horny tip is 9twelfth
