Triassic Echinoderms ot Bakony. 
Outside the Balaton district, the only specimens that I have been able to refer 
to I. tyrolensis major are some from the Upper Cassian Beds between Verwies 
on the Falzarego road and Cortina. They are preserved in the Palaeontological 
Museum, Munich, under the name «Pentacrinus tyrolensis», and registered «1894, 
XIII, 231»; that Museum has kindly presented two of these fragments, an inter- 
syzygium of 6 columnals in all and a series of 4 internodals, to the British Museum 
(registered E 7111). 
Isocrinus tyrolensis var. a. 
(Plate II, figs. 51—53, 55, 56.) 
Material. — Six specimens do not quite agree with the diagnosis of either the 
species or the subspecies just described. They are : a and b from the Quarry near 
Cutting I on the Veszprem-Jutas railway ; c and d from bed e in Cutting I; e and 
f from Jeruzsälemhegy. All are Raiblian. 
a (figs. 52, 53, 55, 56) is an intersyzygium with four internodals including 
the Itypozygal. b (fig. 51) is a single internodal. These two specimens resemble 
one another more than they do the others. 
Description of Specimens. —- Section markedly quinquelobate (b), or 
substellate (a). 
Side-faces as in type of I. tyrolensis. Normal joint-face (seen in b) has raised 
area merging into adradial crenellae, of which there are about five on each side of 
a radial groove; they are not easily distinguished from the peripheral crenellae, 
which are well-marked and may be as many as 24 to the petal; petal-floors depressed. 
Epizygal joint-face has peripheral crenellae still well-marked, but longer and merging 
into the slightly depressed petal-floor. Hypozygal joint-face also has peripheral cre¬ 
nellae well-marked, but sub-confluent externally; an incipient radial triangle, but no 
radial groove; perradial crenellae long; petal-floors slightly raised. From two to 
four cirrals preserved in each radius. Distal face of cirral 3 shows sub-elliptical 
outline produced below, with rim pronounced except below, lumen supracentral, 
surrounded by a stout and very short fulcrum. 
Measurements of a in millimetres : Diameter, 4’4; average height of columnar, 
l'O; length of IR, 2‘4; length of r, 1 *4; transverse diameter of 3rd. cirral, 7*0 ; vertical 
diameter, 0'6 to 0'8. 
c and d are intersyzygia, each with five internodals. Though laterally crushed 
they appear to have resembled a and b in transverse section and in number of 
crenellae. 
e and / are intersyzygia, each with seven internodals. The syzygial faces 
are worn, but present a general agreement with those of a. The fragment e is 
not curved, but the sides of the internode along the interradial ridges are slightly 
concave. f is curved, and its side-faces closely resemble those of the holotype of 
I. tyrolensis. Measurements in millimetres:
