ANOMOCARELLA (?) BURA, new species. 



This species is represented by the central portions of a single head. 

 Glabella convex, subquadrilateral, arching very gently from the occip- 

 ital ring forward, and near the front rather more rapidly downward 

 to the furrow within the frontal rim; without traces of glabellar fur- 

 rows; occipital furrow narrow, clearly defined; occipital ring rather 

 wide, slightly convex, and projecting a little backward at the center; 

 dorsal furrow shallow, narrow, bvit clearly defined. 



Fixed cheeks about one-fourth the width of the glabella; palpebral 

 lobe more than one-third the length of the head, with a relatively 

 broad outer rim, outlined by a very narrow, faintly defined furrow; 

 ocular ridge short, broad, low, and merging into the palpebral lobe; 

 postero-lateral limb short; frontal rim slightly rounded, separated 

 from the glabella and fixed cheeks b}^ a narrow furrow. 



Surface apparentl}^ smooth, but with a few scattered, very fine 

 punctge as seen with a strong lens. The type and only specimen has 

 a length of 3 mm. 



The generic reference of this species is doubtful, as the frontal limb 

 is absent. The quadrangular, smooth glabella, relatively large palpe- 

 bral lobes, and narrow fixed cheeks relate it more closely to Anomo- 

 carella than to other genera. 



Formation and locality. — Middle Cambrian, upper portion of Chang 

 Hsia formation, in oolitic limestone; Chang Hsia, Shangtung, China. 



Collected by Eliot Blackwelder, of the Carnegie Institution of 

 Washington Expedition to China. 



ANOMOCARELLA CARME, new species. 



Outline of head, exclusive of free cheeks, elongate quadrilateral, 

 moderately convex. The convexity of the glabella is so slight that it 

 is scarcely raised above the general surface of the head; its outline is 

 truncato-conical, with the front rounded; the interior cast appears to 

 be without traces of furrows; occipital furrow transverse, narrow, 

 rounded, and shallow; occipital ring of medium width, slightl}- con- 

 vex; dorsal furrow lightly impressed on the sides of the glabella and 

 scarceh" perceptible in front of it. 



Fixed cheeks narrow, scarcely more than a line in front of the pal- 

 pebral lobes; they widen out slightly in front and merge into the 

 frontal liml), and posteriorly into the postero-lateral limb; postero- 

 lateral limbs narrow, length unknown; frontal limb broad, slightly
