Triassic Echinoderms ot Bakony. 
equal length the height of the collerette above the annulus is 2'3 mm. in f, and 
from 1’5 to 1 '9 mm. in h. 
In a strongly striated shaft (i) about the size of h, the number of striae to 
l'O mm. is 8 on the adapical face and about 6 at the distal end of the adoral face. 
2. Radioli spatuliformes. 
(Pl. X, figs. 262-264.) 
From among the 57 specimens of this form found at Jeruzsälemhegy, 19, 
lettered a s, are selected for measurement and outline drawings. All these draw- 
ings represent the outer or adapical face.
