latter are four naked-eyed species, viz. M. proboscidalis (i. e. Dianesa proboscidalis) 

 M. mollicina (Genus?), M. pileata [Oceania pileata), M. aquorea (i. e, ^quorea 

 Forskalina). His descriptions and drawings are very characteristic. The latter were 

 published in a separate volume, of ' Icones.'

Eight species are enumerated under the genus Medusa in this work. One of them is the 

 Medusa palliata of Bohadsch, which is an Actinea, being the Adamsia maculata of British 

 naturalists. Three appear to be naked-eyed Medusse, viz. M. hemisphcerica, M. bimorpha, 

 and M. digitale. The first is the Thaumantias hemisphcerica ; the second and third were 

 communicated to Miiller by Otho Pabricius, the latter being our Turris digitalis.

This work contains several figures of Medusae. Plate ii, figs. 1 and 2, are very bad figures 

 of Saphenia dinema : six vessels are represented instead of four. Plate xii, figs. 1 and 2, 

 is the Thaumantias cymbaloidea of authors, and in all probability a bad representation of 

 T. hemispharica. Plate xii, fig. 13, is either Turris neglecta, or an allied species. Plate 

 xiv, fig. 1, appears to be an Oceania. The two latter are the Oceania tetranema, and 

 0. sanguinolenta of Peron and Leseuer.

Of the Medusae described in this excellent work, M. digitale is our Turris digitalis; 

 M. bimorpha and M. campanula appear also to have been naked-eyed species, though the 

 latter may possibly have been a young Cyancea.

 Royal Swedish Academy,' vol. ix. 



The Medusa here described is probably a naked-eyed species, though I confess I do not 

 clearly understand the figure (not badly executed) given. It is the Linuche unguiculata 

 of Eschscholtz. Actinea pusilla appears to be a floating animal of its tribe, and possibly 

 a species of Arachnactis. Eschscholtz and Lesson make a Medusa of it under the name 

 of Melicertum pusillum. 



1788. J. F. Gmelin. The 13th edition of ' Systema Naturae,' of Linnaeus. 



The Medusae are contained in vol. i, part 6 of this compilation. Such naked-eyed species 

 as are given (viz. Medusa marsupialis, M. hemisphtsrica, M. dimorpha, M. campanula, 

 M. digitale, M. proboscidalis, M. mollicina (?) and M. pileata), are taken from Plancus' 

 Miiller, Otho Pabricius, and Porskal.

A good figure of Thaumantias hemisphcerica is contained in this excellent and most useful 

 work.

A synopsis of the Medusae known up to that time, and a very valuable one for its date 

 The naked-eyed species described by Forskal, Otho Pabricius, &c., are enumerated and 

 characterised with great acuteness. 



1791. The collection of figures of Medusae in the six plates (pi. xc-xcv) devoted to Acalephce, in the 

 ' Encyclopedic Methodique,' contains several naked- eyed species. 

 Plate xcii, figs. 9 and 10, are copied from Slabber, and represent a Turris and an Oceania ■ 

 fig. 11 IS Oceania pileata, copied from Porskal; figs. 12-15 are copies of Slabber's figure 

 of Obeha sph^ulina, and figs. 7-8 of his Medusa perla, both, however, evidently as we 

 have seen, the figs, of higher Medusae. In plate xciii, we have fig. 1 representing 'l>iamBa
