. On the anatomy of vertebrates. Vertebrates; Anatomy, Comparative; 1866. 54 ANATOMY OF VERTEBRATES. python a large, vertically oblong, but short diapophysis extends from the fore part of the side of the centrum obliquely backward : it is covered by the ar- ticular surface for the rib, is convex lengthwise and convex vertically at its upper half, but slightly concave at its lower half. In the rattlesnake the diapo- physis devclopes a small, circumscribed, articular, tubercle, ib. d, for the ' vertebral rib ' or pleur- ajjophysis, pi; a parapo- physis,^', extends down- ward and forward below the level of the cen- trum ; the anterior zy- gapophysis, z, is sup- ported by a process, ib. d", from the upper end of the diapoijhysis. The base of the neural arch swells outward from its confluence with the centrum, and de- vclopes from each angle a transversely-elongated zygapophysis; that from the anterior angle, z, looking upward, that from the posterior angle, r', downward ; both sur- faces being flat, and almost horizontal, as in the Batrachians. The neural canal is narrow ; the neural spine, na, is of moderate height, about equal to its antoro-pos- terior extent; it is compressed and tnuicate. A wedge-shaped process, ' zygosphcne,' zs, is developed from the fore part of the. skeleton of the colii'a {Naija tripihli,nis).
