Chap. VI. TABULAR VIEW. 153 



R cruciatus Ag. — Rhizostoma cruciata Less., Voy. Coquille, PI. 11, 

 fig. 1. — Coast of Brazil (Lesson). 

 Toxoclytus Ag. — Eight short arms with cylindrical base, widening 

 at their extremity into broad, arrow-head like, appendages, 

 bordered with numerous folds of the marginal lobes. 



T. roseus Ag. — Rhizostoma rosea Regn. in Less., Cent. Zool., PI. 34. 

 — Atknitic Ocean, in the Tropics (Reynaud). 



T. Dubreuilli Ag. — Cephea Dubreuilli Beyn. in Less., Cent. Zool., 

 PI. 23. — Rhizostoma Dubreuilli Less. — Gulf of Bengal (Rey- 

 naud). 

 Melitea Per. and LeS., 1809 (name preoccupied). — Orythia Lmk. 

 (p. p.). — Rhizostoma Esch. and Less. (p. p.). — I suspect that 

 the base of the arms alone are preserved in the only figure 

 published of this genus, and that, besides the short lobes rep- 

 resented, it had long arms, like Thysanostoma. 



M. purpurea Per. and LeS. — DeBl, Man. d'Actinol, PI. 35, fig. 5, 

 from a drawing by LeSueur. — Rhizostoma purpurea Esch. — 

 Orythia purpurea Lmk. — New Holland: DeWiifs Land (Peron 

 and LeSueur). 

 Thysanostoma Ag. — Eight very long, papillate arms, with a distinct 

 round lobe, projecting outward from their base. 



Th. Lessoni Ag. — Melitea brachyura Less., Cent. Zool., PI. 80. The 

 name brachyura, for a species with very long arms, cannot 

 be retained. — Rhizostoma brachyura Less., Zool. Coq. — Netv 

 Guinea : Dorehy (Lesson). 

 Evagora Per. and LeS. 1809. — Orythia Lrnlc. (p. p.). — Rhizostoma 

 Esch. (p. p.). Owing to the number of the arms, which 

 exceeds that of the other genera, I have some doubts as 

 to the position of this genus, in the family of Rhizostomidoe 

 proper. As characterized by Peron and LeSueur, this genus 

 embraces two distinct types, one of which, the E. tetrachira, 

 has been removed to Ocyroe (Aurelia) by BlainviUe. 



E. capillata Per. and LeS. — DeBl, Man. d'Actin., PI. 35, fig. 3, 

 from a drawing by LeSueur. — Orythia capillata Lmk. — 

 Rhizostoma capillata Esch. — Neio Holland : EndracMs Land 

 (Peron and LeSueur). 

 2d Family. LEPTOBRAcmDiE Ag. This family embraces Rhizostomeae with 

 veiy long, slender arms, provided with a small cluster of mar- 

 ginal fringes near their termination. Four genital pouches.
