NO. 1458. CAMBRIAN FAUNAS OF CHINA— WALCOTT. 581 



AGRAULOS (?) MELIE, new species. 



Central portions of head, exclusive of the free cheeks, convex. 



Glabella truncato-conical, convex, about one-half the length of the 



head, and marked by three pairs of short, faintly impressed glabellar 



furrows, and a narrow, median, longitudinal ridge; occipital furrow 



[transverse, rounded, shallow, and fading out toward the center of 



[the glabella; occipital segment narrow at the sides, widening rapidl}^ 



[to the central portion, which is as high as the glabella at the back, 



land sloping toward the occipital furrow at the base of the glabella; a 



[minute node occurs at the center of the segment; dorsal furrow 



I shallow, but strongly outlined. 



Fixed cheeks narrow, elevated at the palpebral lobes, and sloping 

 toward the glabella; a narrow ridge extends from the anterior, outer 

 edge of the furrow on the inner side of the palpebral lobe to the 

 furrow in front of the antero-lateral angle of the glabella, which 

 corresponds to the ocular ridge; palpebral lobe long, narrow, and 

 separated from the tixed cheek by a narrow furrow; frontal limb 

 convex, rising to a prominent boss or swelling in front of the glabella, 

 from which it is separated by a strong furrow; at the sides the frontal 

 limb is narrow, and merged into the narrow lixed cheeks; postero- 

 lateral limbs short, narrow, and separated from the tixed cheeks 'b}' a 

 narrow, shallow furrow. 



Surface finely punctate under a strong lens. The largest head in 

 the collection has a length of 6 mm. 



Oh.'^ervations. — This species is characterized by the tumid frontal 

 limb, and the ridge within the palpebral lobe on the fixed cheek, a fea- 

 ture found on Agraidos, but not on an}' of the described forms from 

 China.

Genus ANOMOCARE Angelin. 

 ANOMOCARE BIGSBYI, new species. 



Of this species only the central portions of the head, exclusive of 

 the free cheeks, are known. Glabella moderately convex; a gla])ella 

 9 mm. in length has a width of 9 mm. at the base and 6 nmi. in front; 

 front rounded from the anterior side of the ocular ridges; surface 

 marked by a pair of faintly impressed posterior furrows that extend 

 obliquely backward from the dorsal furrow toward the center; a sec- 

 ond pair of furrows is indicated by a smooth place on the surface; 

 occipital furrow very shallow at the center, broader and slightly
