description, and DeBluinville even published one of the draw- 

 ings of LeSiteiir. This is certainly quite sufficient to establish 

 the priority of the genus Pegasia, and even more satisfactory 

 than the descrijitions of Kdlliko; no one of which is illus- 

 trated. Here are included all the Thalassantheoe, with more 

 than six tentacles, alternating with single radiating pouches. 

 Lesson's genus Scyphis contains many-rayed species of the 

 same type ; no structural differences being indicated. Many 

 species still referred to -^quorea may also belong here, as, 

 undoubtedly, some Polyxenia do, while others are true M- 

 quoridae.

To avoid unnecessary changes, I enumerate here the species 

 described by different authors, under the names under which 

 they were published, though some of those of Quoy and 

 Gaimard, and especially those of Leuckart, of Gegenbaur, and 

 of Kolliker Avill, no doubt, prove identical, as they were all 

 observed in the Mediterranean.
