RE [Cnidaria] help with identification

[Peter.Schuchert at ville-ge.ch]

Dear Deborah,
identifying medusae on photographs is usually rather difficult, sometimes
plainly impossible. Using Arai & Brinckmann-Voss (1980), I would say that

"Little Red email.jpg" looks like:
Trichydra pudica Wright, 1858 (=Pochella polynema Hartlaub, 1917)


while "cnidarian net 2 email.jpg" could perhaps be a young:
Ptychogena lactea A. Agassiz, 1865

For a correct identification I would need the preserved specimens.

Kind regards,
Peter
