NO. 1415. CAMBRIAN FA UNAS OF CHINA— WALCOTT. 5 7 



convex, slopino- obli<}uely downward and passing into the smooth, 

 nearly flat frontal rim almost without interruption from the very 

 shallow transverse furrow; palpebral lobes small, about one-third the 

 length of the glabella. 



The only surface markings are the fine, irregular lines that extend 

 from in front of the glabella outwar^ across the broad frontal limb to 

 the frontal rim. The type and only specimen of the head in the col- 

 lection has a length of 11.5 mm., with a width at the palpebral lobes 

 of S mm; the glabella is 6 mm. in length, the frontal limb 2 mm., frontal 

 rim 1.5 mm., and occipital ring and furrow 2 mm. 



This species is somewhat doul)tfully referred to Anomocarella, as 

 the frontal liml) and rim are relatively long. It resembles Anomoca- 

 rella chinensls in the narrow fixed cheeks and the absence of glabellar 

 furrows.

 Mi Tien formation, in gray, crystalline, fossiliferous lime tone; Chao 

 Mi Tien, Shangtung, China.

ANOMOCARELLA CHINENSIS, new species. 



Head of medium size, moderately convex, and longitudinally irregu- 

 larly quadrilateral, exclusive of the free cheeks. Glabella moderately 

 convex, rising gentl}' from the dorsal furrow toward the center, so as 

 to give it a slightly ridged appearance. A glabella 5 mm. in width 

 has a length of 7 mm., exclusive of the occipital ring; siu-face appar- 

 ently smooth; occipital furrow very slightly defined; occipital ring 

 broad, very slightl}^ convex, with a slight node a little in advance of 

 the center; dorsal furrow shallow, but distinct on the sides and in front 

 of the gla])ella. 



Fixed cheeks about one-half the width of the glabella, slighth^ con- 

 vex; they merge laterally into the furrow outlining the palpebral 

 lobe, and posteriorly slope rapidly to the posterior margin; ocular 

 ridges low, rounded, and passing outward and merging into the narrow 

 palpebral lobe; they clearly mark the division between the central 

 portion of the fixed cheeks and the rapid slope to the frontal rim; 

 palpebral lobes about one-third the length of the head; frontal limb 

 narrow in front of the glabella, widening out at the sides and sloping- 

 downward with a gentle convexity; frontal rim nearly flat, separated 

 from the Frontal limb hy a shallow furrow that curves slightly back- 

 ward near the center so as to form an obtuse angle. In some exam- 

 ples there is a slight deepening of the furrow on each side of the 

 incurved portion of the frontal rim; postero-lateral limbs short, and 

 marked by a rather shallow, broad furrow parallel to their posterior 

 margin.
