The =hand= consists of four digits, that corresponding to the thumb of the human hand, judging from the analogy of the frog probably being the one that is absent. [Illustration FIG. 23.

I. II. III. IV. V. digits.] Each digit consists of a somewhat elongated =metacarpal= and of two or three phalanges. The metacarpals are contracted in the middle and expanded at either end. They are connected with the carpus by cartilage, and the articulations between the several phalanges, and between the metacarpals and phalanges are also cartilaginous. The second, third, and fifth digits have two phalanges apiece, the fourth, which is the longest, has three. The second metacarpal in the specimen examined and figured articulates partly with carpale 2, partly with carpale 3. C. THE PELVIC GIRDLE. The pelvic girdle of the Newt is in a much less modified condition than is that of the Frog (see p. 165). It consists of a dorsal element, the =ilium=, a posterior ventral element, the =ischium=, and an anterior ventral element, the =pubis=, to which is attached an =epipubis=. The =ilium= is a somewhat cylindrical bone which at its ventral end meets the ischium, and forms part of the =acetabulum=. It is then directed upwards and slightly backwards, and is attached to the ribs of the sacral vertebra. The =ischia= are a pair of somewhat square bones which meet one another in the middle line; they form part of the acetabulum, and are united to the ilia above. In front of the ischia is a narrow cartilaginous area which represents the =pubes=. Projecting forwards from it is a bifid cartilaginous =epipubis=. D. THE POSTERIOR LIMB. This is divisible into a proximal portion, the =thigh=, a middle portion, the =crus= or =shin=, and a distal portion, the =pes=. The =thigh= consists of a single bone, the =femur= (fig. 23, A, 1), which has a thin shaft and expanded ends. The anterior part of the pre-axial border and posterior part of the postaxial border bear slight outgrowths. The =crus= or =shin= includes two short bones, the =tibia= and =fibula=, which are nearly equal in length. The pre-axial bone or tibia is a straight bone thickest at its proximal end, the postaxial bone or =fibula= (fig. 23, A, 3) is a rather stouter curved bone of nearly equal diameter throughout. The =pes= includes the =tarsus= or =ankle=, and the =foot=.
