General form subovate, convex; cephalic shield subtriangular, strongly convex; anterior and lateral margins smooth, round edges; posterior lateral angles produced into long subuliform spines; posterior margin nearly transverse; glabella subglobose, constricted at the base, projects beyond the anterior and lateral margins; two minute rudimentary lobes are separated from the anterior lobe by deep furrows each side of the central axis; neck furrows broad and shallow upon the central axis, deepens laterally, and extends to the posterior lateral angles; neck segment a narrow elevated ridge; movable cheeks triangular, convex.

Eyes prominent, subglobose, directed forward and outward from the central eminences of the cheeks; visual surface occupies the outer lateral margins; facial sutures, as far as determined, extend from the posterior third of the lateral margins to the posterior base of the eyes, thence to the top of the eye, curve around the outer margin and then down to the anterior base.

Thorax a little longer than the cephalic shield; axial lobe with ten segments, arching forward, narrows very gradually, posteriorly as wide
