ASAPHISCUS ? ANAXIS, new species 

 Plate 63, figs. 2, 2a 



This species is represented by a number of cranidia from 7 to i6 

 mm. in length. It is characterized by a narrow, upturned frontal 

 border and rather broad, strong glabella and occipital ring. 



Surface as far as known slightly roughened by what may be a fine 

 granulation. 



Cranidia of a similar type occur at several localities in the Mary- 

 ville limestone. 



Formation and locality. — Upper Cambrian : (107) Maryville lime- 

 stone ; Bull Run Ridge, northwest of Copper Ridge, 11 miles (17.7 

 km.) northwest of Knoxville, Knox County; (119) beneath NoH- 

 chucky shale, on Cub Creek, 1.5 miles (2.4 km.) southeast of Morris- 

 town, Hamblen County; also (123b) top of Maryville limestone, 

 near base of Nolichucky shale; Rogersville, 0.5 mile (0.8 km.) east 

 of depot on left of railway, in wagon road, and (125) north side of 

 big creek below Harlan's mill, 4 miles (6.4 km.) northeast of Rogers- 

 ville, last two in Hawkins County, all in Tennessee. 



ASAPHISCUS ? DURIS, new species 

 Plate 63, figs. 8, 8a 



The cranidium representing this species is not unlike that of ^. f 

 Horns, figure 6, but is proportionally broader, and its outer surface is 

 closely granulated. 



Formation and locality. — Upper Cambrian ?: (loyf) ; about 2 

 miles (3.2 km.) north of Bakers Summit, Bedford County, Penn- 

 sylvania. 



ASAPHISCUS ? FLORUS, new species 

 Plate 63, figs. 6, 6a-b 



This is a small species, the cranidium of which would have been 

 referred to Ptychoparia or Liostracns except that the associated 

 pygidium has a slightly concave border and the anchylosed segments 

 are clearly of the Asaphiscus type. 



Formation and locality. — Upper Cambrian ?: (loyg) Kittatinny ? 

 limestone ; Drab, Blair County, Pennsylvania. 



A similar form occurs at locality loye, Upper Cambrian. ?: Kit- 

 tatinny ? ; limestone in lower part of upper quartzite division of the 

 " Kittatinny "; i mile (1.6 km.) southwest of Ore Hill, and 4 miles 

 (6.4 km.) south of Roaring Spring, in Bedford County, Hollidays- 

 burg quadrangle (U. S. G. S.), Pennsylvania.
