NO. 3 CASSIDULOID ECHINOIDS — KIER I99 



interporiferous and poriferous zones wide, with interporiferous zone 

 slightly wider; pores conjugate, outer pore elongated transversely in 

 all petals but less in petal II than in other petals. 



Peristome. — Anterior, round, large. 



Periproct. — Inframarginal, round. 



Floscelle. — Bourrelets present but slightly developed, no inflated; 

 phyllodes (text fig. 165) slightly developed, single pored, with only 

 slight crowding of the pores near the peristome. Three large pits, 

 presumably for sphaeridia, in each ambulacrum behind the buccal 

 pores, with regular arrangement, first pit half -moon-shaped followed 

 by two round pits. 



Occurrence. — Upper Cretaceous ( Maestrichtian-Danian of Dou- 

 ville) from Bekrit, Morocco. 



Location of type specimens. — Sorbonne (Lambert Collection) 

 Paris, France. 



Genus ZUFFARDIA Checchia-Rispoli 



Zuffardia Checchia-Rispoli, 1917. Rend. Roy. Accad. Lincei, ser. 5a, vol. 26, 

 p. 492. Type species by original designation, Pseudocatapygus sanfilippoi 

 Checchia-Rispoli. 



GENERIC DESCRIPTION 



Medium, oval, highly inflated ; apical system monobasal ; petals 

 well developed, broad, ambulacral plates beyond petals single pored ; 

 periproct marginal, longitudinal ; peristome pentagonal, higher than 

 wide ; bourrelets well developed, phyllodes single pored ; buccal pores 

 present. 



Comparison with other genera. — Zuffardia is similar to Pliolampas 

 in having broad petals with broad poriferous zones of equal length, 

 a longitudinal pentagonal peristome, and similar phyllodes. It differs 

 in having a more inflated test, a marginal periproct, and a smoothly 

 rounded posterior margin. 



Range and distribution. — Upper Cretaceous (Senonian) of Tripoli.
