CYTHERIDEIDINAE Sylvester-Bradley and Harding 1952,p.75h-

CYTHERIDEIS yones 1856a,p.157,158 [2 species: C. unisulcata, 
Ce. unicornis] Jones 1857,pe46 (10 species) as 
a subgenus of Cythere. The genus is dead. 
Sylvester-Bradley and Harding 1953 designated 
Ce unicornis as genotype, which was the first time 
one of the original 2 species was designated. C. 
unicornis = Cypridea spinigera Sowerby by Jones 
and Sherborn 1887,p.386, and therefore Cytherideis 
becomes a synonym of Cypridea Bosquet 1852. Many 
of the more than 100 species which have been 
described under the name Cytherideis should be 
transferred to Cushmanidea Blake 1933, or Ponto- 
cythere Dubowsky 1939.
