eye and are gently convex horizontally. Longitudinally they are 

 rather convex to match the curvature of the whole cranidium. Eye 

 lines prominent. Eyes small. The brim is of normal width. The 

 preglabellar area is slightly wider than the rim. The rim is wide and 

 thick in the middle, narrowing gradually toward the anterior angles. 

 However, as the anterior angles are approached the narrowing is 

 much more abrupt, giving rise to a rather peculiar depression in the 

 anterior furrow. The surface, except the bottoms of the furrows, is 

 covered by two sets of granules. A small set somewhat uneven in size 

 is numerous and is overlain by a series of larger granules scattered 

 irregularly over the entire cranidium. In addition, the preglabellar 

 area has vertical anastomosing lines.

KOCHINA WASATCHENSIS, n. sp. 



Plate 12, figs. 12-14 



This species is represented by a number of cranidia none of which 

 are altogether complete. The glabella has the usual shape and size 

 and is slightly keeled. The fixigenes are wide at the forward end of 

 the eye, equaling the full width of the glabella at that point. Eye 

 lines are clearly defined. Eyes small and situated well behind the 

 midpoint of the cranidium. In cross section the fixigenes are gently 

 convex except at the anterior angles, which are considerably depressed. 

 Longitudinally the curvature is also slight. The brim is wide and 

 concave and has the usual rim, which is much more thickened on 

 some specimens than on others, a feature due to the degree of impres- 

 sion of the doublure. Surface nearly smooth except for vertical 

 anastomosing lines on the preglabellar area.

KOCHINA? ELONGATA, n. sp. 



Plate 12, figs. 15, 16 



A single cranidium in the oolitic rock from the Brigham locality 

 lies next to a specimen of Wimanella maladoisis. 



The cranidium is not fully typical of Kochina because of its 

 narrowness and the proportionately great width of the glabella. In 

 some respects it appears to be closer to Inglefieldia. However, the 

 brim structure and eye size and position refer it to the genus rather
