A levision of Ernst Haeckel's determinations of a collection of Medusae 163 



Linerges draco Haeckel. 

 1880, p. 496. 

 (100) 5°N. 107° E., China Sea; Caspersen, 1869. 1 specimen. 

 Haeckel by a misprint gives the longitude as 107" W. in the China Sea. This is 

 the type specimen. Later on the species has been recorded from the Malayan Archi- 

 pelago (Maas, 1903, p. 24) and New Britain (Neu Pommern) N.E. of New Guinea 

 (Thiel, 1927, p. 27). I think we should follow Thiel in regarding it as a valid species. 



Liniscus sandalopterus Haeckel. 



1880, p. 497. 

 [Linuche unguiculata (Schwartz).] 

 (167) 2° N. 21° W., off Sierra Leone, West Africa; Strandgaard, 1857. 4 

 specimens. 

 In his monograph Haeckel also records this species from the tropical part of the 

 Atlantic collected by Koch and Hedemann, but in the list these specimens are deter- 

 mined as Liniscus cyamopterus (see below). Liniscus sandalopterus has not been 

 observed, since it was described by Haeckel, and the specimens evidently belong to 

 Linuche unguiculata. L. sandalopterus accordingly is ah obsolete name. 



Liniscus cyamopterus Haeckel. 



1880, p. 497. 

 [Nausithoe punctata Kolliker.] 

 (103) Atlantic Ocean, without particulars; Koch, 1860. 1 specimen. 

 (106) Atlantic Ocean ; Hedemann. 3 specimens. 

 The specimens are labelled L. cyamopterus, and they are provided with the same 

 name in the list; they are, however, large specimens of Nausithoe punctata Kolliker. 



Pelagia per la. 



1880, p. 506. 



[Pelagia noctiluca ( Forskal).] 



(177) Northern Atlantic; Olrik, 1860. 3 specimens. 

 Pelagia perla is identical with P. noctiluca. 



Pelagia phosphora Haeckel. 



1880, p. 506. 

 [Pelagia noctiluca (Forskal).] 

 (170 and 231) 7" N. 22° W. Hygom, 1850. 3 specimens. 



(171) 8° 38' N. 24° 58' W. Mathiasen. 1 specimen. 



(172) 36°N. 41"W. Galathea, 1842. 3 specimens. 

 (175) 7-13° N. 57° W. Hygom. 6 specimens. 

 (174) Atlantic Ocean ; Hygom. 2 specimens. 



(178) 11°N. 22°W. Hygom, 1853. 1 specimen. 

 (180) Cape Verde Current; Prosch. 4 specimens. 

 (225) 14° N. 20° W. Prosch. 



Haeckel has referred all these specimens to his new species Pelagia phosphora, 

 which, however, cannot be kept apart from P. noctiluca (Forskal). 



A young specimen, labelled Pelagia ju\.. No. 116 in the list, taken in the Bay of 

 Biscay, 47° N. 7° 30' W., likewise belongs to P. noctiluca.
