species, it is doubtful whether one should not distinguish those from the Pachy- 
cardia tuff of the Seiser Alp (Zirret, 1900, Brom, 1900, 1904); while those from 
the Cardita beds of Raiblian age (WoOnrMaNN, 1889) are not C. Buchi, but are 
possibly C. testudo. To these questions we shall recur. 
Anaulocidaris testudo n. sp. 
(Interambulacrals, Pl. VII, figs. 164—187. Radioles, Pl. X, figs. 256—272.) 
Diagnosis. — An Anaulocidaris with relatively thin radioles: Radioli 
remiformes slightly curved downwards and not concave on inner face (length not 
known to reach 20 mm.); Radioli spatuliformes with handle bent at an angle to 
the blade, concavity of inner face rarely exceeding *125 of thickness of blade, no 
distinct ridges (length not known to exceed 183 mm.); Radioli trulliformes with 
width usually exceeding twice the length, ridges from handle to distal angles slight 
or absent, outline of blade six-sided with sinuous distal margin and distinctly bev- 
elled proximal margin, striae passing on to outer face cross one another at right 
angles; Radioli paletiformes with straight sides, bevelled on outer face, which is 
flat, thin blades, ridges of inner face faint or absent. 
Material. — The interambulacrals are mentioned on p. 95. 
The radioles number 473, distributed according to their forms and _ their 
localities as follows:

From among these specimens it is convenient to select as holotype one 
of the spatuliform radioles, comparable with the holotype of Cidarites Buchi Mbnst., 
and to take this from the locality in which the species is most abundant, namely 
Jeruzsélemhegy. As conforming with these conditions I fix on the original of Pl. X. 
figs 262—264. 
Description of the Radioles. — Our knowledge of Anaulocidaris has 
grown up piece-meal, and no complete account of the radioles of the genotype has 
ever been published. The total number of specimens of A. Buchi preserved in the 
Museums of Munich, Vienna, Tiibingen, and London, which, with the exception of 
some at Strassburg, include all the specimens hitherto mentioned in scientific 
literature, does not come near the number of specimens of A. festudo from either 
of the chief Bakony localities. Consequently it seems advisable to base on this 
abundant material a detailed description of the radioles of A. festudo. Except in 
those minor characters which will subsequently be indicated, this description will 
apply also to A. Buchi, and will enable us to reconstitute the whole aspect of this 
remarkable genus. 
The following description is based on the specimens from Jeruzsalemhegy,
