ventral limit and origin, respectively, of the transverse process, a faint impression situated about 1 cm below the articular surface of the proc. oM. post, represents the fossa lateralis arcus vertebrae described by baroness de FEJÉRVÁRY-LÁNGH in the caudal vertebrae of O j)l

h isaurus. On a level with the upper limit of the facies costales, or just a little above it, there is. on each side, a small nutritive foramen —foramina pro introitu ramulorum nutritivorum lateralium ramorum dorsalium arteriarum intercostalium, briefly: foramina nutritiva lateralia — which lie about midway between the facies costales and the antero-ventral edge of the proc. obi. posteriores. Incisura lateralis arcus vertebrae subparaboloid. more rounded and open in the anterior part, because of the anterior outline's following an antero-lateral direction, more strongly bent and rather closed in the posterior one, for the posterior outline's forming an almost right angle with the longitudinal axis of the vertebra. Processus obliqui posteriores considerably smaller than the anterior ones. Such configuration seems to be brought about by the special conditions of strain obtaining in the anterior and posteriorparts, respectively, of the vertebrae: the anterior part has to support the considerable bulk of the posterior portion of the neural arch, that bulk being implied by the very strongly marked caudado rostral declivity of the neural arch and the striking narrowness of the spinal canal. The clarification of the various kinetomeehanical moments that bore upon the peculiar development of the single skeletal elements in Megalania is, as stated above, a task incumbent upon those specialists who are gratified with more or less full sets of the material concerned. — The dorsal surface of the processes under inspection is slightly convex, following a downward direction in distal sense; it is rather smooth, with fine structure lines running parallel to the direction followed by the processes themselves, i. e. at right angles to the longitudinal axis of the vertebra. Greatest distance between lateral edges of proc. obi. post. 111.5 mm. — The posterior (caudad) surface is very large, presenting the shape of an acuteangled equilateral triangle on either side; the facies rhomboideae (FEJÉRV., 1918, emend. F.-LGH., 1923) are, thus, pretty large; they are marked with faint subvertical structure lines, slightly converging towards the linea medialis (FEJÉRV.) visible on the posterior surface of the neural arch. The posterior edge of the articulation surface of the proc. obi. post, is enlarged into a visibly projecting, rather broad torus terminális proc. obi. post. (F.-LGH., 1923) which marks the limit between the oblique processes' articulation surface and their facies
