Pelagia cyanella Peron & Lesueur. 

 1880, p. 507. 

 [Pelagia noctiluca (Forskal).] 

 (176) No locality stated. Galathea exped. 1 specimen, determined P. cyane/lal 



Stenoptycha dactylometra Haeckel. 



1880, p. 526. 



Cyanea capiUata (L.). 



This species is not in the list, and no specimen is preserved, but the coloured 



drawing by H. P. C. Moller, mentioned by Haeckel in his monograph, is in our 



possession. It evidently represents a young Cyanea capil/ata with only 5 tentacles 



in each of the eight groups. 



Cyanea arctica Peron & Lesueur. 

 1880, p. 530. 

 [Cyanea capillata (L.).] 

 (183) Davis Strait; Olrik, 1866. 2 specimens. 

 (220) Greenland; Holboll, 1841. 1 specimen. 

 Haeckel determined these specimens as Cyanea arctica. As previously demonstrated 

 by me (Kramp, 1942, pp. 128 If) the common Cyanea occurring in the Greenland 

 waters and along the east coast of North America differs in no way from the European 

 C. capillata. 



Aurelia flavidula Peron & Lesueur. 



1880, p. 555. 



[Aurelia limhata Brandt.] 



(181) Davis Strait; Olrik, 1866. 5 specimens. 



The complicated history of the Greenland and East- American forms of Aurelia 



was thoroughly dealt with by me in a previous paper (Kramp, 1942, pp. 109 ff), to 



which I refer, especially concerning the discussion (p. 122) of the specific names of 



the two species. The present specimens belong to the yellow form with complexly 



branching and anastomosing canals described from the northern Pacific by Brandt 



(1838) as Aurelia limbata. It was probably the same species, which was observed at 



Greenland by O. Fabricius (1780), and it was to this that Peron and Lesueur applied 



the name A. flavidula. Unfortunately, L. Agassiz accepted this name for the common 



American Aurelia which, however, belongs to the same species as the European 



A. aurita (L.), though the American form differs somewhat from the European and 



should be designated as a distinct variety, A. aurita var. occidentalis (Kramp, 1942, 



p. 125). 



This variety of A. aurita also occurs along the southern part of the west coast of 

 Greenland ; it is not mentioned in Haeckel's list, but to a drawing by H. P. C. Moller 

 of a six-rayed specimen (locality not stated) Haeckel has added the name Aurelia 

 flavidula var. sex radiis. Another drawing by Moller ( Frederikshaab, 1 839) apparently 

 represents A. limbata.
