BIBLIOGRAPHY. 



In order to facilitate the studies of those among my readers who may be inclined to 

 pursue researches among the Pulmograda Gymnopthalmata, I have drawn up the following 

 catalogue raisonne 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 Medusae. 



1739. Janus Plancns. ' 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, /, under the description of "Urtica soluta 

 Marsupium referens et motus vitaleis manifestissime edens Maris Ariminensis." The 

 figure, plate xcii, fig. 9, of the ' Encyclopedie Methodique,' is sometimes quoted as if it 

 had been taken from Plancus, and represented the same species (2d ed. of Lamarck, 

 An. sans Vert., vol. iii, p. 131), but is really copied from Slabber, and represents in all 

 probabiUty an Oceania. 



1746. Linnaeus. 'Fauna Suecica/ 1st Ed. 



In the first edition of this work three Medusse are enumerated, of which the third is a 

 naked-eyed species. " 1288. Medusa orbicula cruce alba picta. Hsec 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. Linnaeus. ' Systema Naturae,' 10th Ed. 



Medusa cruciata, M. pilearis, and M. marmpialis, are the naked-eyed species enumerated. 



1758. The Rev. W. Borlase published his ' Natural History of Cornwall,' in which there are some of 

 the earliest figures of British Medusse, 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 Marinae Aquae Innatantibus 

 atque in Littoribus Belgicis obviis," in the ' Acta Helvetica,' vol. iv, p. 38. 



In his paper is contained the first notice of Thaumantias hemisphtsrica. The description is 

 fiill 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 quae in Itinere Orientali observavit Petrus Forskal. 

 Post mortem auctoris edidit Carsten Niebuhr.' Havniae, 1775. 



Forskal observed and described twelve pulmograde Medusae during his voyage. Of these, five 

 were inhabitants of the Red Sea, and the remainder of the Mediterranean. Among the
