skull. ‘Together the parietals form a wide oval inclosing on the 
median suture the circular pineal foramen. ‘The parietals are 
sculptured with coarse radiating grooves and ridges much after the 
manner of 7°. radiatus. ‘The pittings present on that form are, how- 
ever, absent here. The sutures bounding the supraoccipital are toler- 
ably well assured and these show that element to have been rather 
large, quadrate and with the usual relations for the element. The 
epiotic is distinct. It is triangular and small. It is produced into an 
angle on the posterior border strongly recalling a similar condition in 
T. punctulatus Cope. The boundaries of the prefrontals and the 
upper borders of the maxillae are not clearly ascertained. ‘They may 
have had the outline indicated (Fig. 11). The lachrymal has not 
been detected. The postfrontal and postorbital form the posterior 
boundary of the orbit although the limits of the latter element have 
not been definitely ascertained. The position of the squamosal is 
well assured, although its entire boundaries are not determined. It 
has the usual relations of the squamosal and joins the parietal broadly. 
The jugal is broad and widens posteriorly to abut on the supratem- 
poral which, as usual, forms the quadrate angle of the skull. The 
sutures bounding the quadratojugal and the posterior end of the 
maxilla are not determined. 
There are but two fragmentary vertebrae preserved and an estimate 
based on the length of these remains gives about thirty presacral 
vertebrae. ‘The structure of the vertebrae preserved cannot be ascer- 
tained but the neural spines appear to have been low and stout. 
There are six elements of the pectoral girdle preserved. ‘These 
are: the two clavicles, the interclavicle, the coracoid of one side and 
the scapulae. ‘The interclavicle is rhomboid in form and acuminate 
posteriorly. It is sculptured with radiating grooves and ridges. 
The interclavicle is different from the same element in 7. punctulatus 
Cope in that the base is acuminate, not truncate, as in the latter form. 
The clavicles present much the same shape as does that element in 
T. tabulatus Cope. It is ornamented by a sculpturing of radiating 
lines which take their origin from the lower external angle as the bone 
lies in the matrix. The clavicle is somewhat triangular in shape and 
lies close to the skull, but this close approximation of the pectoral 
elements to the cranium is due probably to post-mortem shifting since
