190 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. I44 



late, perforate tubercles on both adapical and adoral surface except 

 in medial region of interambulacrum 5 adorally; large nonscrobicu- 

 late, noncrenulate, nonperf orate tubercles on adapical surface and 

 in medial region in interambulacrum 5 adorally. 



Occurrence. — Upper Cretaceous (Maestrichtian) of France. 



Location of type specimen. — Not known. 



Remarks. — Lambert and Thiery (1921, p. 374) and others have 

 considered Lamarck's Galerites ovatiis as a nomen nudum and used 

 Goldfuss's Clypeus leskei instead. However, Lamarck includes a 

 description of his species, and it cannot be considered a nomen nudum.

 p. 79. Type species by original designation, Galerites oi'alus Lamarck, 1816. 



Remarks. — Phylloclypeiis De Loriol is a junior objective synonym 

 having the same type species as Clypeolampas.

Synonyms : Hiingaresia Szorenyi ; Psendovulechinus Szorenyi. 



GENERIC DESCRIPTION 



Medium to large, inflated, smooth marginal outline, often with 

 greatest width anterior to center, adorally flattened; apical system 

 tetrabasal ; petals broad, open, unequal, posterior petals longer than 

 others, outer pore greatly elongated transversely, joined to inner pore 

 by narrow conjugation groove ; ambulacral plates beyond petals single 

 pored ; periproct inframarginal, transverse ; peristome anterior, wider 

 than high, pentagonal ; hour relets well developed, phyllodes broad- 

 ened, single pored, with many pores ; buccal pores present ; no large 

 tubercles adapically, tubercles slightly larger adorally, with narrow 

 naked zone in middle of interambulacrum 5. 



Comparison with other genera. — Vologesia is very similar to 

 Clypeolampas. Both genera have a large test, strikingly similar 

 petals with narrow, slitlike outer pores in the poriferous zones, 

 inframarginal transverse periproct, and an inflated adapical surface 

 and flattened adoral. Vologesia differs in having no large tubercles 

 adapically and in having a less developed floscelle with less inflated 

 bourrelets, and narrower, less crowded phyllodes.
