NO, 3 CASSIDULOID ECHINOIDS — KIER III 



this species, it could not be known whether this species was closely 

 related to Echinolampas or Conoclypiis. The presence of phyllodes 

 with buccal pores is evidence that jaws did not occur in E. raulini.

Material. — One specimen studied from the Lambert Collection at 

 the Sorbonne, and one from the Museum of Comparative Zoology, 

 Harvard. 



Shape. — Very large, subcircular, domed, adoral surface flat. 



Apical system. — Monobasal, with small ocular plates. 



Ambulacra. — Petals long, extending almost to margin, broad, with 

 interporiferous zones four times width of poriferous zones ; pores 

 slightly conjugate, outer pore of pore pair slightly elongated trans- 

 versely, inner round; poriferous zones of unequal length: more 

 pore pairs in right zone of petal III, posterior zones of petals II and 

 IV, and outer zones of petals V and I ; petals straight, with no 

 tendency to close distally. 



Periproct. — Inframarginal, transverse. 



Peristome. — Slightly anterior, transverse, pentagonal. 



Floscelle. — Bourrelets well developed, inflated, vertically sided, 

 phyllodes (text fig. 93) well developed, slight broadening near peri- 

 stome ; single pored, with many pores arranged in three series in each 

 hal f -ambulacrum : 10 to 12 in each outer series, 6 to 8 in each of 

 two inner series. 



Occurrence. — Miocene of Mediterranean countries. 



Location of type specimen. — In Michelin Collection, probably at 

 £cole des Mines, Paris.
