 Christian PIeinrich Pander. 

 Rytidolepis Pander, 48; orthotype R. quenstedti Pander (fossil). Besides this 

 nominal genus, the following additional generic names have been given in 

 this paper by Pander. All are based on fragments of dermal armor, not 

 identified and some of them, according to Eichwald (1860), likely to belong 

 to Eurypterid crustaceans rather than to fishes. These are Coccopeltus, 

 Cyphomalepis, Trachylepis and Phlebolepis. The following is the list of 

 these nominal genera and their type species as given by Woodward : 

 Rytidolepis (uenstedti), 48. 

 Schediosteus (mustelensis), 49. 

 CoccoPELTus (asmussi), 50. 

 Cyphomalepis (egertoni), 51.
