P. Labiclie Fsck — Cyanea. Labiche Q. and G., Yoy. Uran., PL 84, 

 lig. 1. — Pacific, wider the Equator (Quoy and Gaimard). 



What Pelagia australis Per. and LeS., and Pelagia conifera 

 Less., may be, I am unable to say. The species of this genus 

 are very closely allied, and vary greatly, according to their 

 age. Most of the descriptions thus far published contain only 

 delineations of individuals, and not specific characteristics. 



Placois Ag. — ^dQ ^. 125. — Pelagia Esch. (j). p.). 



P. discoidea Ag. — Pelagia discoidea Esck, Acal., PL 7, fig. 1. — 

 Southern Atlantic, near the Cape of Good Hope (Eschscholtz). 



Chrysaora Per. and ZeS., ^sc/^. — Restricted by At/., p. 125. 



C. hysoscella Esch. — Medusa hysoscella Lin. — Medusa fusca Penn. 

 — Medusa tuberculata Penn. — Aurelia (?) crenata Cham, and 

 E//S., Nov. Act., 1821, PL 29. — L>al>/cll, Rare Anim., Vol. I. 

 Pis. 15 and 17. — Cyanea chrysaora Ciiv. and M.-Ediv., in Cu- 

 vier's Regne Anim., PL 47. — Cyanea punctata Z?h^". — Chrys- 

 aora LeSueur Per. — Chr. aspilonota Per. and LeS. — Chr. 

 cyclonota Pa: and LeS. — Chr. spilhemicona Per. and LeS. — 

 Chr. spilogona Per. and LeS. — Chr. pleurophora Per. and 

 LeS. — Chr. mediterranea Per. and LeS. — Chi', macrogona 

 Per. and LeS. — Chr. cyclonota Gosse, Devonsh., PL 2. — Chr. 

 heptanema Per. and LeS. — Chr. oculata Less. — German Ocean 

 (Linnaeus) ; British Channel (Chamisso and Eysenhardt) ; Havre 

 (Peron and LeSueur) ; Atlantic Ocean (Vandelli and Lesson) ; 

 Mediterranean (Peron and LeSueur). 



Thus far, only one species of this genus is satisfactorily 

 known; but no comparisons have as yet been made to 

 ascertain whether specimens from the Mediterranean are 

 identical or not with those of the Atlantic and of the Ger- 

 man Ocean, though Peron and LeSueur have distinguished 

 several species among them. A comparison of the best figures, 

 such as those of Milne-Edwards, Gosse, Dalyell, and Chamisso. 

 does "not afford the means of settling this question. Nor 

 does Lesson's figure of Chrysaora oculata, Acal., PL 6, fig. 2, 

 differ. It is impossible, from the descriptions, to ascertain 

 Avhat are the generic affinities of the species named by Peron 

 and LeSueur, Chrysaora pentastoma, from Napoleon's Land (Aus- 

 tralia) and hexastoma, from Van Diemaiis Land; nor can 

 Lesson's Chrysaora cruentata be identified.
