The axis has a sharp hypapophysial ridge extendingfrom below the base of the odontoid process to beyond the poste-rior surface of the centrum, where it underlaps the next similar ridge and backwardly produced process are developedfrom the two succeeding cervicals, beyond which the ridge gra-dually subsides to the seventh vertebra. From the third to thesixth cervical inclusive, the pleurapophysial part of the transverse. 1 xcir. p. 218, no. 925, a., figured in xcv. pi. vi. fig. 2, also in xcvi, fig. 344. SKELETON OF AKTIODACTYLA. 461 process equals or exceeds the length of the vertebra, and thoseparts are arranged so as to overlap each other. There is a dis-tinct, but less extensive diapophysial portion projecting externalto the vertebrarterial canal: this part alone represents the trans-verse process in the seventh cervical. The spines of the thirdand seventh cervical vertebras are vertical, those of the inter-mediate ones incline forward. The spines of the anterior dorsalvertebras are remarkable for their height, those of the posteriordorsal and of the lumbar vertebras for their antero-posteriorextent, the anterior angle being produced forward and overlappingthe spine in advance. A distinct metapophysis begins to bedeveloped from the second dorsal, and attains its greatest lengthon the twelfth. There are no anapophyses. The notches forthe nerve
