Horizon and locality: Collected at Mazon Creek in 1S71, near Morris, Illinois The remains on which the present species is based consist of an almost entire skull, 26 consecutive vertebrae, both fore limbs, 20 ribs preserved on the right side of the body, and a portion of the ventral armature (plate 4, fig. 4). The skull is very broad posteriorly, its width being one-third greater than its length, with due allowance for crushing. A pineal foramen is not preserved. The sutures bound- ing the premaxillaries, the maxilla?, the nasals, the prefrontals, the frontals, a portion of the parietals, the squamosal, the supratemporal, the quadratojugal, and the quadrate (?) are fairly well preserved. The arrangement of these elements can be discerned by reference to figure 29. The prefrontals are unusually large and are triangular in shape. The supra- temporal is also quite large. The surface of the skull bones is smooth and there is nowhere an indication of sculpture. Portions of 4 sclerotic plates are preserved in the right orbit. These measure by mm. The orbits are large and the interorbital space is less than the transverse diameter of the orbit. Thirteen teeth, apparently pleuro- dont, are preserved on the left maxilla. They are short, sharply pointed, smooth, and unequal. The first 2 left maxillary teeth from the anterior end are short; then follows a tooth which is one-third longer than these two; the fourth tooth is somewhat shorter than the third; the fifth and sixth are still shorter and are practically equal in size, though somewhat larger than the first two. The right mandible is preserved almost entire, though so badly eroded that l
