BIBLIOGRAPHY. 
In order to facilitate the studies of those among my readers who may be inclined to 
pursue researches among the Pu/mograda Gymnopthalmata, I have drawn up the following 
catalogue raisonné of authors, works, papers, and figures bearing upon the subject, not 
confining the notices to British species only, but extending them to all described or figured 
forms of Naked-eyed Meduse. 
1739. Janus Plancus. ‘ De Conchis minus notis Liber. 4to, Venice. 
In this is contained the first figure of the Carybdea marsupialis,—and a very miserable 
representation it is,—in Plate iv, f. 5, f, under the description of ‘“ Urtica soluta 
Marsupium referens et motus vitaleis manifestissime edens Maris Ariminensis.” The 
figure, plate xcui, fig. 9, of the ‘ Encyclopédie Méthodique,’ is sometimes quoted as if it 
had been taken from Plancus, and represented the same species (2d ed. of Lamarck, 
An, sans Vert., vol. ii, p. 131), but is really copied from Slabber, and represents in all 
probability an Oceania. 
1746. Linneus. ‘ Fauna Suecica, 1st Ed. 
In the first edition of this work three Medusz are enumerated, of which the third is a 
naked-eyed species. ‘1288. Medusa orbicula cruce alba picta. Hee omnium minima 
est, tota gelatinosa vitrei coloris, discum pingit crux magna alba, ad margines usque 
extensa, margo integer est: caret appendicibus omnibus, sc. cavitatibus, pistillis, 
staminibus, branchiis.” p. 368, 
In the second edition the specific name Cruciata is added. 
1758. Linneus. ‘Systema Nature.’ 10th Ed. 
Medusa cruciata, M. pilearis, and M. marsupialis, are the naked-eyed species enumerated. 
1758. The Rey. W. Borlase published his ‘ Natural History of Cornwall,’ in which there are some of 
the earliest figures of British Medusee, but no naked-eyed species is represented by him. 
Pennant (British Zoology, vol. iv, 1787) and Turton (British Fauna, 1807) contented 
themselves with following Borlase, making no additions to his list. 
1760. L. T. Gronow (Gronovius). ‘ Observationes de Animalculis aliquot Marine Aquze Innatantibus 
atque in Littoribus Belgicis obviis,” in the ‘ Acta Helvetica,’ vol. iv, p. 38. 
In his paper is contained the first notice of Thaumantias hemispherica. The description is 
full and good for its time; the figure bad, and scarcely recognisable. Cydippe pileus is 
described and figured in the same paper. 
1775. P. Forskal. ‘Descriptiones Animalium que in Itinere Orientali observavit Petrus Forskal. 
Post mortem auctoris edidit Carsten Niebuhr.’ Havniz, 1775. 
Forskal observed and described twelve pulmograde Meduse during his voyage. Of these, five 
were inhabitants of the Red Sea, and the remainder of the Mediterranean. Among the
