Fixed cheeks very narrow, forming' little more than a convex ridge 

 between the dorsal furrow and the furrow within the palpebral lobe; 

 they slope rapidly to the front, merging into the frontal limb, and pos- 

 teriori}^ downward to a very short postero-lateral limb; palpebral lobes 

 narrow, about one-third the length of the head; ocular ridge low and 

 merging into the rim of the palpebral lobe; frontal limb short and 

 sloping downward to a slightly convex frontal rim that is about twice 

 as wide as the frontal limb in front of the glabella; the line of demar- 

 cation between the frontal limb and rim is little more than a change in 

 direction of the slope, the slope of the rim being less. 



The outer crust is exfoliated over most of the head. Where pre- 

 served, the outer surface is smooth under a strong lens. The length 

 of the head of the. type specimen is 12 mm.; the glabella, exclusive of 

 the occipital groove, 6 mm.; frontal limb, 1 mm.; frontal rim, 2 mm. 



This species is doubtfully referred to the genus Anomocm'e^ as 

 the glabella does not have the parallel sides so characteristic of that 

 genus and the palpebral lobes are rather short. The reference to 

 Anoiiiocare is based on the character of the frontal rim, narrow fixed 

 cheeks, and the general configuration of the glabella.

ANOMOCARE BIANOS, new species. 



This species is represented by a portion of the glabella and the 

 frontal limb. The glabella appears to have been quadrilateral in 

 outline, broadly rounded in front, and moderately convex. It is 

 marked in the cast of the interior by very slight traces of three pairs 

 of short glabellar furrows and a very slight, narrow, median ridge; 

 dorsal furrow shallow, but well marked; frontal limb nearly flat for a 

 distance of 2 mm. in front of the glabella, where it curves downward 

 at an angle of about iS'^ for a distance of 3.5 mm. It is quite probable 

 that at the angle between the flat portion and the sloping front there 

 was some indication on the outer crust of a division between the 

 two parts; if so, the shorter inner portion would be the frontal limb, 

 and the sloping outer portion the flat frontal rim. Exterior surface
