Agassiz, 1862 ( Kramp, 1959 ) . Remarks: For the diagnosis see Schuchert (2007) . The genus currently comprises the species Catablema vesicarium (A. Agassiz, 1862 ) , C. multicirratum Kishinouye, 1910 , and C. nodulosum Bigelow, 1913 . According to Hartlaub (1914) , Kramp (1959 , 1961 , 1968 ), Arai & Brinckmann-Voss (1980) , and Schuchert (2007) , the three can be distinguished as follows, characteristics that were also used to identify the present material: C. vesicarium ‒ up to 32 tentacles, rarely 48, bell size up to 3 cm , in North Atlantic and Arctic Sea C. nodulosum ‒ 8 to 16 tentacles, bell-size up to 2 cm , in North Pacific C. multicirratum ‒ 80 to 160 tentacles, bell size up to 6 cm ; in North Pacific and Arctic Sea.
