The crocodile is the nearest to thetypical condition in the musculature of the lateral and ventral part of the tail muscula-ture forms a broad mass that extends to the endof the tail; it lies immediately under the skin andsprings from the caudal ribs (transverse processes—Gadow) and from the spinous processes of all thecaudal vertebrae. The entire side musculature ofthe tail ends cephalad in several portions; the mostventral and medial of these bound the cloaca as anat least slightly developed, morphological sphinc-ter; the lateral portion is attached to the pos-teroventral border of the ischium; while thedorsal portion is inserted by two heads on the firstcaudal rib and on the posterior spine of the
