The fixigenes are almost flat and slope down from the dorsal furrow 

 in line with the lateral slope of the glabella. Surface finely granulose.

DRUMASPIS BRISCOENSIS, new species 



Plate 5, Figures 4-8 



This species is represented by several cranidia, of which two ex- 

 foliated examples are figured. 



The glabella is rectangular, with a practically straight front margin 

 and slightly rounded anterior angles. Four sets of furrows are clearly 

 defined in exfoliated specimens. In cross section the glabella rises 

 with a flat curvature above the dorsal furrow, while longitudinally it 

 is curved throughout, the curvature increasing from the rear forward. 

 Brim of moderate width consists of a thickened rim, widened slightly 

 in the middle. Fixigenes at their widest point slightly more than a 

 fourth the glabellar width. Eyes rather sharply bowed. Anterior 

 fixigenes depressed sharply. Portion of the test preserved appears to 

 be smooth,

DRUMASPIS GOODSIRENSIS, new species 

 Plate 5, Figure 9 



Only the holotype cranidium has been found at this locality. 



The glabella tapers slightly forward to a straight anterior margin. 

 'Jlie usual three pairs of glabellar furrows are developed. Owing to 

 crushing in the shale matrix, the convexity cannot be determined. The 

 fixigenes at their widest point are a little more than a third the glabellar 

 width. The eyes are not greatly bowed and, because of the relatively 

 great width of the anterior fixigenes, depart from the course of the 

 dorsal furrow only at a small angle. Brim of average width, con- 

 sisting of a slightly thickened rim of about the same width as the 

 anterior furrow.
