ns. They taper very much in the other direction. Longest rib, of which there are 8, is 18 inches; also two abdominal ribsaftd three phalanges. These were found in a slab at the Waipara, close to the vertebrae (10 d),and the evidence for connecting them with this genus is afforded by thepeculiarly-excavated form of the head of the rib, which appears to tit thearticulated surface on the tubercle, and also their striated surface ; and, further,certain fragments of spinous processes intermixed with the ribs also assist inthis determination. No. lOy.—Three caudal vertebrae, from the Amuri Bluff, evidently belongto the same species with the above, and form one of the most importantlinks in connecting palaeontologically these widely-separated localities. No. 10^^.—A slab of 20 caudal vertebra3, chevron processes, and neuralspines, which also belong to this species. Obtained from the base of theboulder bed at the Amuri. The most anterior vertebra is 2*3 inches in diameter, whilst the last

There is,however, one detached vertebra of minute size, the centrum being only•75 inch, which would apparently indicate that the diameter of the caudalvertebrae either diminished suddenly, or that the number must have been verygreat. The length of the centrum is 1-5 to 1-2 inches, while that of thesingle small vertebra is only 5 inch. They are all proccelian, quadrilateral in section, with a small triangularneural canal, enclosed by a stout spinous process 3 inches in height by 1 inwidth. The chevron bones are 5-5 inches in length, the bifurcate processes 1-5,articulating with facets on the lower aspect of the centra, and obliquelydirected backwards, in the same way as the first of the series of chevronbones in the Tuatara. No. 10 c.—Eight vertebrae from another slab, also from the Amuri Bluff,probably from the cervical portion of the column. They are
