Chaperia bilamellata Waters, 1898. 
In this list given by Levinsen there is not a single species recognized as iden¬ 
tical with the genotype of Jullien. The best known species of this group is Chap¬ 
eria galeata Busk, 1852. The best figures have been drawn from the fossils. The 
only good figures of the recent specimens have been given by Jullien, 1888, which 
have not the characteristic lamellae. On the contrary, Chaperia bilamellata Waters, 
1898, has been perfectly drawn with its chitinous appendages. Levinson classified 
this genus in the Bicellariidae.
