Four frontal lobes well marked, median pair extremely narrow, sep- 

 arated by a deep and narrow triangular fissure which is rounded 

 at the base; lateral fissures short, also rounded. The broad pre- 

 orbital lobe which covers the eyestalk has a closed fissure, the outer 

 piece of the lobe overlapping the inner and forming a slight 

 emargination on the anterior edge. Middle and outer lobes of supra- 

 orbital margin subtriangular and blunt; middle lobe with inner edge 

 slightly concave, outer slightly convex; outer lobe with nearly 

 straight margins, the outer one about half as long as inner; exor- 

 bital tooth broad, trending inward, outer margin more or less con- 

 vex. Antero-lateral lobes 2, dentiform, subequal, acute, outer mar- 

 gins convex, inner straight or a little concave, sinuses forming a 

 small U ; a third tooth is very small but dentiform. Lower margin 

 of orbit oblique, the inner lobe slightly in advance of the line of the
