seem to be sufficient ground for such a subdivision. I think it would 

 be better if all were placed with Athoryhia, as separate genera, in the 

 Agalmidie, and no subdivision of the group of any other kind at present 

 attempted. 



In the Neue Beitrdge, Gegenbaur substitutes the name Stephanomia 

 for that of Forskalia to designate a well-known form. He says, however, 

 nothing about the genera Halistemma and Agalmopsis, and neither 

 appears in his scheme of classification at the end of that work. Possibly 

 he considers both as simply species of Agalma. 



That which Claus in the last year (1879) has described and figured 

 under the name of Agalmopsis ittricularia, ought to be a new genus 

 rather than a species of Agalma or Agalmopsis.'^ 



There seems no reason why the name Stephanomia, which Lesson ap- 

 plied to both Stephanomia contorta and Apolemia uvaria of later authors, 

 should designate the form with a biserial row of nectocalyces that it now 

 does. Apolemia (PI. I. fig. 1) is a well-marked genus. Leuckart adopts 

 the name Forskalia of KoUiker in his Siphonoj)horen von Nizza, and in 

 his Zoologische Untersuchungen applies the name Stephanomia to the 

 same genus. He rightly says of the so-called Forskalia that it was first 

 described by Milne-Edwards under the name of Stephanomia contorta 

 {Siphonophoren von Nizza, p. 93). 



St. delle Chiaje's use of the generic name, in a description of Stephano- 

 mia ophiura, although hardly accurate enough to be quoted in this dis- 

 cussion, should be mentioned. His designation of a species as ophiura 

 is still retained in the nomenclature, and the form is easily to be known 

 from contorta, from which even the fishermen of Messina distinguish it, 

 although they affix to both a characteristic name, " Pinie di Mare." 



KoUiker {Siphonophoren von Messina, p. 18) says that Lesson is 

 wholly in error, " Wenn er die Stephanomia contorta und prolifera von 

 Milne-Edwards zu derselben {Apolemia uvaria) zieht." In the Nachtrag 

 to the same work he says : " Immer hin bleibe ich bei dem Genus For- 

 skalia das nach einem vollstandigen Thiere gebildet ist und kann der 

 Name Stephanomia fiir das nur unvollstandig bekannte Thier bleiben 

 fiir das er von Peron zuerst aufgestellt wurde." The "unvollstandig 

 bekannte Thier " was that same form whose anatomy Huxley later pub- 

 lished under the name which Peron gave it, although he says that 

 Peron's sketch has "no scientific value." What animal Peron had will
