 Cytaeis tetrastyla Eschscholtz. 



Cijtaeis tetrastyla Eschscholtz, 1829, p. 104, taf. 8, fig. 2. (For synonymy see 

 Hartlaub, 1911, p. 139; Vanhoffen, 1911, p. 204).

These specimens support Vanhoffen 's (1911) contention that a 

 single species of Cytaeis inhabits all three great oceans, for I can find 

 nothing to separate them from the series collected by the Albatross 

 in the eastern Pacific (Bigelow, 1909a, p. 190, "C. vulgaris"), with 

 which they agree, not only in general structure, and in the pigmenta- 

 tion of the cores of the tentacles, but in the presence of Medusa buds 

 on the walls of the manubrium.
