STEPHANOCARE ? MONKEI, new species 



Plate 14, fig. 7 



Steplianooare sp. Monke, 1903, Jahrb. Konig. Preuss. Geol. Landesanst. und 

 Bergakad., Vol. 23, Pt. i, p. 144, pi. 8, figs, i, la, 2-4. (Described and 

 discussed.) 



Doctor Monke doubtfully refers a cephalon, two pygidia, and a 

 free cheek to Stephanocare. Similar pygidia occur on the platy 

 limestones collected by Mr. Blackwelder and as they are clearly dis- 

 tinct from any described species I give them the specific name of 

 S. ? monkei in recognition of the most excellent work done by Doctor 

 Monke on this interesting fauna. The generic reference is in doubt 

 as we have no entire specimens of Stephanocare richthofeni Monke 

 and of this species for comparison. 



Formation and locality. — Middle Cambrian: (C6) thin slabby 

 limestone in the upper shale member of the Kiu-lung group, 2.5 

 miles (4 km.) southwest of Yen-chuang, Sin-t'ai District, Shan-tung, 

 China. 



Collected by Eliot Blackwelder. 



PTYCHOPARIA GRANOSA, new species 



Plate 14, fig. 8 



Ptychoparia granulosa Walcott, 1905, Proc. U. S. National Museum, Vol. 

 29, p. 78. (Species described as below. This species is believed to be 

 congeneric with Hall and Whitfield's species; since the name granulosa 

 is therefore preoccupied for Ptychoparia, granosa is proposed.) 



Not Crepicephalus {Loganellus) granulosus Hall and Whitfield, 1877, 

 Geol. Expl. Fortieth Parallel, Vol. 4, p. 214, pi. 2, figs. 2, 3. 



The gently convex central portions of the cephalon, exclusive of 

 the free cheeks, are all that is known of this species. These indicate 

 a rather broad, semicircular cephalon, with small free cheeks, wide 

 fixed cheeks, narrow, short, convex glabella, and narrow, flattened 

 frontal rim ; glabella marked by three pairs of faintly impressed but 

 clear glabella furrows ; frontal space between the glabella and rim 

 broader than the frontal rim and slightly convex ; palpebral ridge 

 narrow, clearly defined, and merging into a rather small pye lobe. 



Surface finely granulose.
