The type species is Cyta-is tetrastyla Eschscholtz, 1829, of the Mediterranean and eastern 

 parts of the tropical Atlantic. Eschscholtz states that it has 8 simple oral tentacles and 4 

 marginal tentacles, but he figures at least 10 oral tentacles. More recently species of Cyttcis 

 have been found with 8, 16, or even 32 oral tentacles.
