Triassic Echinoderms of Bakony. 
of the markings, which appear to be relatively, as well as absolutely, more delicate. 
In E. granulosus the sutures are crenelate; or, if the crenellae cannot be seen, 
that is due to the presence of a peripheral rim, which structure does not occur in 
any of the present specimens. From all other species of Encrinus or Entrochus 
that I can find described, and certainly from all named Triassic species, E. can- 
cellistriatus differs in the same points as do the striate trochitae of E granulosiis. 
The relatively large number of specimens, their occurence at two localities, the 
absence of the striate form of the true E. granulosus, and the structural features 
just mentioned prevent me from regarding the columnals as derived merely from 
dwarfed individuals of E. granulosus. It is however possible that they represent a 
small race of a species as yet undescribed and living at a later date. Thus, a frag- 
ment of Hallstätter Kalk from Steinbergkogel, preserved in the Hofmuseum at Vienna, 
is full of columnals closely resembling those of the present species, though the largest 
attains a diameter of 4'7 mm. with a height of 1'8 mm. A similar but much larger 
form from the Hallstätter Kalk of Leisling near Goisern, and from the Karnische 
Stufe, zone of Tropites subbullatus , from Rapoltstein near Hallern, Salzburg, is also 
in that Museum. 
Encrinus sp. 
(Plate I, fig. 23.) 
A single columnal from the Cassian of Cserhät is placed with this genus 
because of its general resemblance to certain Entrochi assigned to E. cassianus by 
Laube (1865), especially that represented in Münster (1841) pl. V, fig. 4 c, and to 
a less extent that in Laube (1865) pl. VIII a, fig. 5g. 
Side-faces convex, with, in addition, a well-marked ridge, at about half the height, 
slightly wavy in outline and a little irregulär. Ridges on joint-face not clear, about 15, 
apparently short. 
Diameter at ridge 1’65 mm. Diameter at joint-face L3 mm. Height 1‘2 mm. 
Encrinus sp. 
Two columnals from Muschelkalk of Felsöörs, and Tamäshegy near Balatonfüred 
are too ill preserved to be further determined. Their measurements in millimetres are:
