NO. 3 CASSIDULOID ECHINOIDS — KIER I9I 



Remarks. — I was unable to find any specimens of the type species 

 of this genus but studied seven species of Vologesia ovum (Gratte- 

 loup), a species that appears to be congeneric with it. I include a 

 photograph (pi. 35, fig. 5) of one of these specimens and a text 

 figure of one of its phyllodes (text fig. i6i). The apical system is 

 tetrabasal in this species. 



Range and distribution. — Upper Cretaceous (Cenomanian to Mae- 

 strichtian) of Europe and Persia. 



Synonym of VOLOGESIA 



Hungaresia Szorenyi, iQSSa. Geo!. Hung., ser. Palaeont., vol. 26, p. 76. Type 

 species, Hungaresia hungarica Szorenyi by original designation. 



DESCRIPTION OF TYPE SPECIES 



VOLOGESIA HUNGARICA (Szorenyi) 

 Plate 33, figures 5-7; text figures 183, 184 



Hungaresia hungarica Szorenyi, 1955. Geol. Hung., ser. Palaeont., vol. 26, 

 P- 77, %• 25, pi. ID, figs. 14-22. 



Material. — Two specimens, a cast of the holotype, and new photo- 

 graphs were studied. 



Shape. — Large, 53 mm. long, elongate, with well-rounded anterior, 

 posterior margin, highly inflated adapical surface, flat adoral, sharp 

 margin, steep sides. 



Apical system. — Anterior, tetrabasal, with large madreporite (text 

 fig. 183), small genital plates 3, 4, i. 



Ambulacra. — Petals long, open, narrow, with narrow interporif- 

 erous zones, wide poriferous zones with conjugate pores, outer pore 

 very elongated transversely, slitlike. 



Periproct. — Inframarginal, transverse. 



Peristome. — Very eccentric anteriorly, transverse, pentagonal, small. 



Floscelle. — Bourrelets well developed, inflated ; phyllodes widened, 

 single pored, with two series of pores in each half -ambulacrum (text 

 fig. 184) ; buccal pores present. 



Location of type specimen. — Hungarian Geological Institute, Buda- 

 pest. 



Occurrence. — Upper Cretaceous (Senonian), Sumeg, Kovesdomb, 

 Bakony. 



Remarks. — Szorenyi states that this species has a monobasal apical 

 system, but the system is definitely tetrabasal (text fig. 183). Her 

 species is almost indistinguishable from Vologesia ovum (Gratte-
