PLATE VII 
Fig. 1. Ciidochiriis sp. Species described by Springer. Anal side of calyx 
with arms attached. From the soft clay at the top of the Brassfield formation 
at the quarry northwest of the railroad station at Centerville, Ohio. 
Fig. 2. Stereoaster squamosus sp. nov. A, entire specimen, actinal side. 
B, the greater part of the same specimen enlarged. ^ C, a part of one of the arms 
enlarged still further. The arms are numbered with Roman numerals. The 
arrows in figure 2C point to depressions within which the pores are seen to occur 
in pairs; the letter a in the same figure points to a large pit for which there ap- 
pears no structural reason. The overlapping of the plates within the central 
area is seen best within the lower, lefthand side of this area, and near the basal 
parts of ray II in figure 2B. There is no evidence of system in the arrangement 
of the plates, such as would be expected among the Stelleroidea.
