' For this type see the papers and works, 

 quoted above, of KiJlliker, Gegenbaur, Leuckart, 

 and Huxley. For the embryology, especially the 

 paper of Gegenbaur on Diphyes turgida, Zeits. w. 

 Zool., 1834, p. 332, and for the budding, tlie work 

 of Huxley, especially PI. 5. The Calycophorida; 

 Leuck. do not constitute a natural division, since 

 the communities of the Hippopodidaj have not the 

 same organic complication as the Diphyid.T, while 

 the PrayidK have. The AbylidoB differ from the 

 two latter families, by the great inequality, angular 

 form, and position of the twin sterile Medusas. 



- To this genus belong also D. Boryi Q. and 

 G. — D. eampanulifera Escli. ; Gegenb., Neue Beitr., 

 PI. 30, figs. 23-26.— D. angustata Escli., Ac, PI. 12, 

 fig. 6. — D. regularis Meyen, and D. Steenstrupii 

 Gegenb., Neue Beitr., PI. 29, figs. 27-29. 



^ It is my impression that D. appendiculata, 

 Escli., Ac, Ph 12, fig. 8; Hurl, PI. 1, fig. 2. — D. 

 Sieboldii Koll, PI. 11, figs. 1-8 (with which D. 

 gracilis Gegenb., Zeit. w. Zool., PI. 16, figs. 5-7, 

 and D. acuminata Leuck., Zool. Unters., PI. 3, 

 figs. 11-19, are synonymous), and D. Kochii Will, 

 belong to another genus for which the name Muggisea 

 BuscJi may be retained. D. biloba Sars ; D. Sarsii 

 Gegenb., Neue Beitr., PI. 30, figs. 30 and 31 ; D. 

 turgida Gegenb., Zeitsch. w. Zool., 1854, PI. 23, 

 formerly D. Sieboldii Gegenb., and D. truncata Sars, 

 Faun. litt. Norv., PI. 7, figs. 1-15, form a third 

 genus, for which I propose the name of Huxleyia. 

 The generic relations of the many species of this 

 family have not yet been sufficiently considered, 

 nor is it easy, when the young and adult and 

 the secondary buds differ so widely.
