* T here use Diaphana for the restricted genus Utriculus, as adopted by G. 0. 
Sars. It is peculiar in lacking the odo ntophore. Utriculus is predccupied by 
Schumacher (1817). Our “Utriculus Gouldii” is, in its ; and de — a 
lichna and should called Cylichna na Gouldii. The Diaphana pertenuis 
(Migh.) is very distinct from it.
