The remains of //. aciedentatits are too scanty to warrant much certain inference as to its form. Its vertebrie would seem to have resembled those of H. Lyelli, but to have been elongated and more thoroughly ossified. Its ribs are similar in form and proportion to those of the last-named species. A pelvic bone and some detached phalangial bones, as well as very fragmentary limb bones, would indicate that its limbs were well developed. Its external scales are similar to those of the last species, but larger, and a few fragments of skin show scales and appendages similar to those of H. Lyelli, but of greater dimensions. The microscopic structure of its bone is also 2 B I li â¢,i' ; I f -Id B.
