and are about equally long. The ilium is small and elongated. It 

 joins the ischium behind, and from the point of union a small 

 forwardly directed pubis is given off. The hind limb is large and 

 well preserved. The tibia and fibula are both remarkably widened 

 at the distal end. The tarsal bones are few in number ; astragalus, 

 calcaneum, and two tarsal bones of the second row are identified. 

 There are five digits in which the number of phalangeal bones 

 is 1, 2, 3, 4, 3. 



Splienosaurus Sternbergii (Herm. von Meyer). The skull in this 

 type is unknown, and the skeleton described has already been treated 

 of by Fitzinger and von Meyer. It consists of 18 thoracic vertebree, 

 sacral vertebra, and a few tail-vertebrge, the pelvis and both femora. 

 The characters of the vertebrae may be sufficiently gathered from the 

 accompanying figures.

The early ribs are six times as long as the vertebra with which 

 they are connected ; but they are shorter posteriorly, so that the loth 

 is only as long as the vertebra. Caudal ribs are developed and attached 

 by a broad plate which makes the base triangular. The pelvis 

 resembled that of Chelydosanrus. 



Cochleosaurus Bohemicus. — This species is known from a skull, in 

 which the anterior part is not preserved, but the length is estimated 

 at 17 cm. and the breadth at 15 cm. The orbits are relatively small, 

 oval, separated by twice their diameter. The parietal foramen is 

 inconspicuous. The upper surface of the skull is covered with 

 angular pits of varying size, which radiate over the bones on which 

 they occur, and obscure the sutures. The jugal bones are unusually 

 wide and large. The supra-occipital bones are prolonged backward 

 into remarkable spoon-shaped processes, more like those which are 

 common in the epiotic bones. A second species, Cochleosaurus falax, 

 is founded on a supra-occipital bone of a small animal, in which the 

 posterior process is expanded in a triangular form. The surface of 

 the bone is marked with two large furrows and many small ones. 



Gnudrya latistoma has a skull which is semicircular in front, with 

 densely placed teeth in the premaxillary and maxillary bones ; the
