somewhat truncate as in 7. ¢abulatus Cope and other species of the 
genus. The distal extremities of the quadrates do not project as 
far backward as do the supraoccipitals. The skull roof is formed 
of the regular elements except that a quadrate seems to be indicated 
by a scale of bone on the posterior angle. The nostrils are oval and 
the pineal foramen is small. 
The premaxilla is probably a relatively large element though its 
boundaries are not definite. The nasal is of an oblong shape and

borders the frontal anteriorly. The frontal forms the whole of the 
interior border of the orbit and borders the parietal broadly behind. 
The parietal is a large element and the pineal foramen is inclosed in 
the median suture about midway of the parietals. ‘The supraoccipital 
is wider than long and with the epiotic forms the greater part of the 
posterior border of the skull. The prefrontal apparently forms the 
entire anterior border of the orbit and sends an acuminate projection 
to the side of it. The maxilla is excluded from the orbit and is an 
elongate element with sharp conical teeth of which there are four 
preserved. These measure about one millimeter in length. The 
jugal lies along the lateral border of the orbit and it is acuminate 
both anteriorly and posteriorly. It borders the supratemporal
