Diagnosis.
Small colonies that show all the basic characters listed above for the family Cordagalmidae and are particularly distinguished by the presence, on all the tentacles, of tentilla that, as
Carré (1968)
remarked were devoid of desmonemes and acrophores, characteristically present in the adult terminal filaments of many monoecious physonect siphonophores, such that those of
Cordagalma ordinatum
have come to be called "tentilles de
type
larvaire" or larval-type tentilla. The palpons do not have a palpacle.
