width of poriferous zones; petals with tendency to close distally. 

 Pores conjugate, outer pore elongated transversely, inner round. 



Periproct. — Inframarginal, transverse. 



Peristome. — Anterior, depressed, pentagonal with steep sides. 



Ploscelle. — Bourrelets well developed, inflated; phyllodes single 

 pored (text fig. 90), in ambulacrum III two series of pores in each 

 half-ambulacrum, 8 to 10 in each outer series, 4 to 6 in each inner; 

 in other ambulacra usually 3 series in each half -ambulacrum with 2 

 to 4 pores in a middle series ; buccal pores present. 



Occurrence. — Recent of Indian Ocean. 



Location of type specimen. — Unknown. 



Remarks. — Echinolampas ovifonnis has been considered by most 

 authors as a junior subjective synonym of Echinanthus ovatus Leske. 

 As discussed in more detail on page 226, Leske's figure of his E. ovatus 

 is so poor as to make positive identification of it impossible. 



Synonyms of ECHINOLAMPAS 



? Aplolampas Lambert, 1906. Ann. Soc, Alpes-Maritimes, vol. 20, p. 32. Type 

 species by monotypy, Echinolampas montevialensis Schauroth. 



Remarks. — Lambert actually erected this genus for the specimens 

 that Dames (1878, p. 42) referred to Echinolampas montcvialensis. 

 In 1918 Lambert made a new species Aplolampas lonigcnsis for these 

 specimens of Dames's and stated that this new species was the type 

 species of his Aplolampas. This action is not valid, however, since 

 only the species referred to in the original description can be the 

 type species. E. montevialensis must be the type species. Unfor- 

 tunately, Schauroth's figures of this species are very crude, and it 

 is not possible to know many of its generic or specific characters. It 

 does resemble Echinolampas, and Aplolampas is herein provisionally 

 considered a synonym of Echinolampas. Lambert's A. lonigensis has 

 never been well figured either, and its generic affinities are not clear. 



Craterolampas Cotteau, 1891. Pal. franc, ech. fiocene, vol. 2, p. 186. Type 

 species by original designation, Echinolampas raulini Cotteau.
