immense masses off Algoa Bay, South Africa, and was called by 

 them Fritillaria, until they afterwards became acquainted with 

 the descriptions of Chamisso and Mertens. Recognizing as they 

 do the priority of discovery of the former, they yet adopt the 

 name conferred by the latter, and, without any very just reason, 

 give to the specimens observed by themselves a new specific 

 name, 0. bifurcatn.'" 



This is wrong in so far as the name Fritillaria is concerned, 

 which was not mentioned by Quoy & Gaimard, but must date 

 from Huxley, having the same hologenotype as Agassiz's name, 

 and thus becoming an absolute synonym of it. But Oikopleura 

 hifurcata Q. & G. appears unrecognizable. In the belief that 

 he was saving this generic name, as in the case of Appendicularia, 

 Fol in 1874* emended the diagnosis of Fritillaria to fit a group 

 of organisms which he had described in 1872. t Fritillaria Fol 

 1874 is therefore preoccupied by Fritillaria Huxley, 1857, and 

 since no other generic name appears to have been proposed to 

 replace Fritillaria Fol, 1874, 1 suggest for it the name Fritillura 

 designating Fritillaria magachile Fol as type.
