deeper toward the sides, with a shallow pit near the dorsal furrow; 

 occipital ring- of medium width, very slightly convex; dorsal furrow 

 shallow, but clearl}' indicated at the sides and front of the glabella. 



Fixed cheeks naVrow, flat opposite the palpebral lobes; the}' curve 

 gently down toward the posterior furrow and more abruptly in front; 

 palpebral lobes small, less than one-tifth the length of the head; the 

 marginal rim is prominent, and passes obliquely into the low, broad 

 ocular ridge which crosses the cheek obliquely to the antero-lateral 

 angle of the glabella; frontal limb sliglitly concave, passing with very 

 slight interruption into the flattened rim, the line of demarcation 

 between the limb and rim being little more than the angle formed by 

 the union of the sloping limb with the more nearl}' horizontal rim. 



Surface minutel}' grarudar, the granules being irregularly distrib- 

 uted, and rising abruptly' from the general surface, A head 15 nun. 

 in length has the same width at the palpebral lobes. 



Ohservafions. — This species ma}' be compared with Anomocare tem- 

 enus Walcott," A. latelimhatum, Dames,'' and A. f dauUs Walcott.'' 

 From the flrst it differs in its broader glabella and less distinctly 

 marked line between the frontal limb and rim; from the second it 

 differs in a more rounded glabella, and narrower frontal limb; and 

 from the third in having a more conical glabella and less concave 

 frontal limb. The small palpebral lobe is like that of Anomoeai'e 

 hergio7ii Walcott.'' It may be that the two species will be found to 

 belong to another genus. 



Fonnation and locality. — Middle Cambrian; 4 miles south-southwest 

 of Tung-yii-chon, Shen-si, China.

ANOMOCARE ERIOPIA, new species. 



The description of Anoniocare teimntis^XaV'ott'' covers the principal 

 features of this species. A. ei^iopla differs in having a broader tixed 

 cheek, less distinctly defined furrow between the frontal limb and 

 frontal rim, and in the absence of a median ridge on the glabella. The 

 associated pygidium differs from that of A. temenii^ in having a pro- 

 portionately more convex axis, smaller pleural lobe, and in having the 

 furrows on the pleural lobe extend nearh^ across the border of the 

 pygidium. A. criopla differs from ^4. taflan Walcott' in its broader 

 frontal lind), and more depressed frontal limb and border, broader 

 fixed cheeks, and less distinctly defined glabella.
