Crinoidea, Encrinidae. 
17 
Total length of fragment about 34 mm. Width 8'6 mm. Average height of a 
columnal 1'5 mm., with no obvious alteration of height. Section circular. Side-face 
flat or slightly convex. Crenellae visible from outside, though not very clearly. 
Lumen apparently rather small, but its outlines are not distinguishable. Radial striae 
clean-cut but not deep, and apparently reach lumen. The ridges gradually increase 
in width, and some of them fork at about half-way to the periphery. The total 
number of crenellae cannot be counted, but I should estimate it at not less than 50. 
The relative size of the crenellae agrees with that in typical examples of E. silesiacus, 
and their number is consistent with the slightly greater diameter. There is no trace 
of cirri. 
This determination is of importance, because there is believed to be no other 
evidence for the age of the rock in this locality. This evidence indicates a Lower 
Muschelkalk age. 
Entrochus sp. 
(Plate I, fig. 26.) 
There is a fragment from the Cassian beds of Cserhät, consisting of two 
columnals which can not well be referred to any described species. 
The height of a columnal is L25 mm., the diameter is L5 mm. The sides 
are slightly convex. One joint-face shows very fine radiating striae, which are not 
quite regulär, but seem to anastomose. 1 The suture between the ossicles is obscure. 
The other joint-face scarcely shows the striae, only a faint roughness, perhaps due 
to weathering. 
With this may provisionally be placed two columnals, also from Cserhät, that 
have joint-faces similar to the last mentioned, and convex sides. Their measurements 
in mm. are: 
Diameter . . . 1'3 1‘5 
Height . . . . l'l 0'75 
TrochUa sp. 
(Plate I, fig. 27.) 
A single columnal from the Cassian beds of Cserhät. Sides smooth, slightly 
convex. Joint-faces show a minute axial canal, a smooth depressed central area, 
surrounded by slight, irregulär elevations, which might be crenellae either worn or 
modified; they are short and do not quite reach the periphery. 
Measurements: Height 1'3 mm.; greatest diameter 1'5 mm. 
This reminds one of Eugeniacrinus or possibly Millericrinus rather than of 
Encrinus. 
Entrochus sp. indet. 
Three fragments of columns from the Cassian beds of Cserhät, and one 
columnal from bed e 4, at cutting VI on the Veszprem-Jutas railroad, are not 
well enough preserved for description. They are all of small diameter. 
1 The arrangement of the striae reminds me of the specimen that S. v. Wöhrmann referred 
incorrectly to Encrinus granulosus (Jahrb. d. k. k. Geol. Reichsanst., Wien, XXXIX. p. 191, pl. V. 
f. 8; 1889). That, however, has a diameter of 5‘8 mm.; it came from the Cardita Oolith of Sun- 
tiger, Plaller Anger (See p. 11.).
