Chaperia tropica Waters, 1909. 



Chaperia galeata Busk, 1852. 



Chaperia bilamellata Waters, 1898. 



In this list given by Levinsen there is not a single species recognized as iden- 

 tical with the genotype of JulHen. 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 hilamellata Waters, 

 1898, has been perfectly drawn with its chitinous appendages. Levinson classified 

 this genus in the Bicellariidae.
