THE STATUS OF THE TUNICATE GENERA APPEN- 

 DICULAR! A AND FRITILLARIA. 



BY PAUL BARTSCH. 



Appendicular ia Chamisso & Eisenhardt; hologenotype Appen- 

 dicular ia flagellum Cham. & Eis., 1821,* appears unrecognizable. 

 With the intention of saving this generic name, Fol in 1874 

 decided to give it a new status by redefining it and applying 

 it to organisms typified by Appendicidaria sicula, Fol. In reality 

 Fol here creates a new genus, Appendicular ia,'\ with A. sicida 

 Fol as hologenotype. 



This genus of Fol's has been recognized by subsequent writers 

 on the subject as the basic genus Appendicidaria. Appendicidaria 

 Fol, 1874, being preoccupied by Appendicidaria Cham. & Eis., 

 1821, according to the rules requires a new name and I propose 

 in its place Appendicula with Appendicidaria sicida Fol as holo- 

 genotype. 



Fretillaria was cited by Agassiz, 1846,+ but Quoy and Gaimard 

 referred to the animals as Fretillaires § and described them 

 under the name Oikopleura hifurcata Q. & G.ll Agassiz there- 

 fore becomes the author of the genus Fretillaria and Oikopleura 

 hifurcata is the hologenotype. 



Huxley in his ' ' Remarks upon Appendicularia and Doliolum" 

 states : 'i 



" The only other notice of the genus (so far as I am aware) 

 is that given by MM. Quoy and Gaimard. It was observed in
