The jaws are straightand rather long, the lower very deep at the base. There aretwelve cervical vertebra?, eight dorsal, twelve lumbar and sacral,and eight caudal. The ribs, eight in number, are stout, thetwo anterior incomplete. Of the caudal vertebrre the last oreighth is extremely large, presenting a broad plate beneath ;the seventh is anchyloscd with it; the eighth has a deep notchbehind at its lower part, into which is received the very stronginferior spinous process of the sixth, when the tail is do^vnward curve of the tail is performed chiefly at thejoints between the fifth and sixth, and the sixth and the latter the tail may be curved upwards, so as to lie flat 70 PICIN^. on the back. This, however, is not peculiar to lateral processes of the caudal vertebrae are very large, soas to prevent much lateral motion. In the accompanyingfigure, which represents the sternum of Picus pileatus, the. body is seen to have two notches on each side behind, a ratherlow crest or ridge, which however is much prolonged anteriorly,a slender furcula, of which the crura are extremely compressed,and not widely separated, long coracoid bones, and scapulaesingularly curved downwards and enlarged at the end, inwhich respect they differ from those of any birds known to humerus is large, and has a small bone in its metacarpus consists of two undivided bones; there are,besides the pollex, two digits, one of two phalanges, the otherof one. The pelvis is of moderate size. The femur also mode-rate. There is a small patella. The tibia is rather stout, andthe fibula extends to half its length ; the tarsal bone is slender;the phala
