CYTHEREIS, Skogsberg 1928,p.38-56, described as a sub- 
genus of Cythereis Jones, a Cretaceous genus, but 
actually based for the most part on Cythereis 
(Cythereis) montereyensis, nespe, living 
California. Skogsberg indicates the type must be 
one of Jones species, but does not indicate which. 
He divides his own species into 6 groups, some 
of which are quite different from C.(C.) monte- 
reyensis and would fall within Hemicythere Sars 
1925. This subgenus = Eucythereis Klie 1940, by 
Klie in his description. 
CYTHERELLA [6 species, the lst. Cytherina ovata Roemer 1840, 
pel04,pl.16,f.21 being designated genotype by 
Ulrich 1894,p.684] Jones 1849,p.28 [as subgenus 
of Cythere by Jones; Cypridae-Cytherinae by Brady

CYTHERELLIDAE Sars 1866,p.124, a family of Podocopa for the 
genus Cytherella. 
CYTHERELLIFORMES Skogsberg 1920,p.158, a suborder "for all
