Aiiiin.il -mall, ovate in outline, tapering posteriorly from the base of the 

 rephalon; protuberant anteriorly. (Vphalon with entire, broadly .subcircular anterior 

 margin-. geiial angles obtusely rounded, surface elevated, flattened above. Qlabella 

 pmtiiberan*. its convex frontal lobe extending considerably beyond the anterior 

 margin of the shield; obovate; greatest width across the anterior portion of the 

 frontal lobe and equal to the axial length. Anterior margin subcircular to the do 

 furrows which are deep, convergent and slightly incurved. Lateral furrows obscure, 

 lint still more distinctly developed than is usually the case in species of this genus. 

 The first pair lies a short distance from the anterior extremities of the dorsal 

 furrows, is short and directed somewhat anteriorly; the second and third furrow- 

 are but slightly longer, somewhat more transverse. None of these pass far inward 

 and their inner extremities are separated by a regularly convex median portion of 

 the glabella. They are equidistant and the lobes are, therefore, of about the same 

 size. One-half the length of the glabella is taken by the frontal lobe and the width 

 of the glabella at its base is one-half its width at the base of the frontal lobe. 

 < 'ccipital groove narrow, occipital ring broader than the lateral lobes and extending 

 considerably beyond the base of the glabella, forming a proportionally broad axis. 

 Kye-nodes very convex, the eyes themselves being small, elevated and situated at 

 about the middle of the cheeks. Outwardly, beneath the eyes, the surface is 

 depressed convex. The facial sutures terminate posteriorly, directly at the genal 

 angles. The occipital groove i- dearly defined over the cheeks and is continuous 

 with a lateral marginal groove. Surface coarsely and evenly tubercled over the 

 glabella and the cheeks, within the marginal furrow. .

 segment, thence gradually tapering. The pleura-, at about the middle of then -width,
