laterall}^ merges into the fixed cheek; from another point of view the 

 dorsal furrow might be considered to pass outside of the narrow, 

 elongate lobe, near the base of the glabella, and the furrow between 

 the glabella and the elongate lobe would then be an inner division of 

 the dorsal furrow. The surface of the glabella is somewhat irregular 

 on account of the lateral furrows, and a rather rounded, broad longi- 

 tudinal ridge which extends its entire length. 



Fixed cheeks less than half the width of the glabella; they rise from 

 the dorsal furrow and merge into the large eye lobe, and anteriorly 

 are divided by the strong ocular ridge which passes into the strong 

 palpebral lobe; in front of the ocular ridge the cheeks slope down- 

 ward to a second ridge which extends from the front line of the gla- 

 bella sub-parallel to the ocular ridge as far as the facial sutures; 

 frontal limb relatively long, slightly concave to the narrow, very 

 slightly rounded rim; postero-lateral limbs short and marked by a 

 strong curve within the narrow posterior rim. 



Surface smooth under a strong lens. 



The associated pygidium has a strong central axis marked by five or 

 six rings that are very distinct on the broad planulate margins. This 

 species is strongly characterized by its peculiar glabella with the 

 elongate, narrow lobes near its base; also by the broad, slightly 

 convex frontal rim. 



Formation and locality. — Middle Cambrian. Upper part of Chang 

 Hsia limestone, Chang Hsia, Shangtung, China.

ANOMOCARE DAUNUS, new species. 



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

 limb, and a fragment of a large, free cheek associated with it; also an 

 associated pygidium which has the same characteristic surface marking. 



Glal)ella slightly convex and marked by three pairs of very faintly 

 indicated furrows; it has a length of 16 mm. with a width of 12 mm. 

 near the base; it narrows slightly toward the rounded front; a fragment 

 of the fixed cheek indicates that the latter was nearly fiat between the 

 glabella and palpebral lobe; the frontal lobe is nearly flat for a distance 

 of 4 mm., when it .slopes downward to the thickened frontal rim, no 

 line of demarcation distinguishing the frontal rim. 



The free cheek indicates a moderate convexity for the head; also 

 that the margin, which is very narrow at the front, widens out grad- 

 ually toward the postero-lateral angle of the head; the base of the eye 

 lobe shows that the palpebral lobe and eye were relatively small; the 

 line of facial suture, as shown by the free cheek, shows that the postero- 

 lateral limb of the fixed cheek was large and more than half the width 

 of the cheek; also that the antero-lateral limb was strong.
