s I have seen the posteriortendinous ends of the longissimus dorsi extend beyondthe hinder opening of this channel, and in some casesalmost reach the superior caudal muscles. Of course,in Eeptiles, the muscle is continuous the entire lengthof the back and tail, to the very tip of the latter. In our subject the longissimus dorsi also arises bya series of short and distinct tendons alternately fromthe anterior and posterior extremities of the summitsof the neural spines of all the dorsal vertebra3.It will be remembered that the free margins of theseneural spines above are l^ifurcated behind and pointedin front. Now the tendons of this series attached tothe points in front extend forwards and merge intothe muscle, and are tendons of insertion, while those Opisthotenar (Tnnerer Bauch).
