Chart X\'I. • Finds of Lcuckartiara nobilis Hartlaub. O Uccurreiice in the North Atlantic according to the literature ▲ Occurrence of Catablema mullicirrala Kishinouvc in the North Atlantic. two quadrants, two in eadi of the two otlK-rs. The number and arrangement of young tentacles cannot be determined. It appears from the above that the mode of dcveh)pnient of tlie tentacles in Lcuckartiara nobilis is sometimes octagonal, sometimes duodecimal, both cases about equally frc(iuent, and sometimes both represented in one and the same individual, some of the (juadrants ha\ing 2 tentacles of 2nd order, others only one, which is tlien placed interradially. — Inirther it will be observed that e\en in tlie largest specimens the number of fully developed tentacles does not exceed 12 or 16 (according to the mode of development), and all the other tentacles are much smaller. During tlie hrst time the dcvclopmenl of the tentacles ])rocceds very gradually, and tentacles of every size are found. At a diameter of about 10 mm tjie jierradial tentacles are still somewhat larger than the next ones, but shortly afterwards the indixidual lias evidently attained its maximal number of fully developed tentacles (12—16), and all the others remain nuuli smaller, no middle- sized being found; the number of small tentacles is, however, continually increased, at least for some time. This fact establishes a characteristic difference between L. nobilis and L. brcviconis: in the latter species
