The original <>f this evidently new form is a part of a cephalon (considerably 

 more than one-half), preserving the outline of the frontal and lateral limb and the 

 confiKiir.it ion of the surface. The anterior curve is subseraicircular, broadly round- 

 ing to the sides where the margin is straight for a considerable distance, thence 

 incurving rather abruptly at the angles of the genal expansions. The outline thus 

 formed may be termed subquadrate-ungulate, and its peculiar curve is a distinguish- 

 ing character of the species.

General surface of cephalon moderately elevated. C label la subtrigonal, tapering 

 anteriorly to an obtusely' rounded extremity. Length about one-half that of the 

 cephalon axial ly; slightly greater than the width across the base. The top of the 

 glabella is somewhat abraded but its lobatipn is quite distinct, showing that the 

 frontal lobe is long and conical, extending for about one-third the glabellar length, 

 the first pair of lateral lobes faint, the second pair a little longer; the third pair is 

 comparatively large, ovoid, attached by a narrow neck to the basal and most elevated 

 portion of the glabella. Of the glabellar furrows the third are largest and deepest 

 Occipital furrow broad and shallow; occipital ring narrow in the middle widening to 

 the axial furrows. The frontal limb is broad, convex just in front of the glabella 

 becoming deeply concave and elevated at the margin, to the full hight of the glabella. 

 This general concavity of the marginal area is continued over the cheek, to the 

 extremity of the cheek-spine, becoming, however, less, posteriorly. The outer 

 marginal nm '* thickened all around; the inner margin elevated but not thickened 

 except at the continuation of the occipital ring on the cheeks. Eyes situated in a 

 transverse line which crosses the glabella at about one-third its length from the 

 anterior extremity, elevated and widely separated from the glabella by the broad 

 dorsal furrows. A low ocular ridge extends from them obliquely backward toward 

 the posterior extremity of the glabella.
