208 7 Triassic Echinoderms of Bakony. 
Horizon, «in einem gleichfalls schwarzgrauen, etwas verwitternden und dann 
schmutzig gelblichbraun erscheinenden Kalksteine», now recognised as Raiblian. 
Remarks on previously described Specimens. — The radioles 
of the holotype are peripheral and infra-ambital. Those referred by ScHarHAuTL to 
C. marginata, and transferred by Wourmann (1889, p. 195) to C. parastadifera, 
are probably circumapical or possibly secondary radioles. 
The localities given by Wourmayn are Ostreenkalk of Haller Anger, Baren- 
alpe, etc. The original of his fig. 19 is from Ueberschall, Haller Anger, and is 
preserved in the Palaeontological Museum, Munich, the authorities of which have 
kindly permitted me to study it (Pl. XIII, fig. 375). The holotype I have not seen, 
but ScHaFHAUTL’s account and figures are so clear, and have been so thoroughly 
checked by Wourmann, that this is no serious omission. 
Material from Bakony.— Fragments from beds a and b of Cutting IV 
on the Veszprém-Jutas Railroad number 648, a few being on matrix; from Cut- 
ting I are 12, without bed designated, and 6, of which some are doubtful, labelled 
bed e; from the quarry near Cutting I are 129, four being on matrix; from Jeru- 
zsalemhegy, 43: — Total = 837. Although the species is abundant at Cutting IV, 
most of the specimens are very fragmentary, and a large number are obscured by 
an oolitic growth; those not thus broken or obscured are chiefly the smaller forms. 
The specimens from the other localities are as a rule better preserved, and since 
the largest selection is afforded by the Quarry near Cutting I, the following account 
will be based on those except when other localities are definitely mentioned. 
In length complete radioles range from 4°5 mm. to 11°6mm.; but some frag- 
ments indicate radioles of slightly greater length. The longest complete radiole is 
one on matrix from Cutting IV, 12°7 mm. long, and there is no evidence that this 
length was ever exceeded. The mean between these two extremes agrees almost 
exactly with the 85 mm. given by ScuarHduTL as the average length. 
In shape the radioles, whatever their length, vary much, being either baculi- 
“form, or sub-clavate, or bilaterally compressed and lanceolate, with all intervening 
variations, and even triangular in section. The major axis is generally straight, 
but may be curved, even markedly so. Pari passu with the variation in shape, 
the greatest thickness varies much, both absolutely and in relation to the length. 
This will be clear from the following measurements.
