and was so obscure that it escaped the search of even a careful in- 

 vestigator like Sherborn. 



I therefore conclude that the continued use of Salpci should not 

 be afifected by the existence of Dagysa; and that Dagysa should not 

 be used until, and unless, it be definitely proved to denote some 

 genus that is not Salpa. 



I agree, however, with Clause 2 of the drafted Opinion, and 

 therefore I concur in Clause 3. 



Hoyle : I am of the opinion that the use of Dagysa for Salpa will 

 cause much confusion. Salpa is a name used not only by specialists 

 but in laboratories, text-books and numerous books of travel. Under 

 these circumstances I am obliged to divide my vote on the final c[ues- 

 tion as I cannot vote fo^ or against in toto. 



CASE'-' OF APPENDICULAR! A 1820, OIKOPLEURA 1831, 



APPENDICULARIA 1874, APPEXDICULA 1915, 



AND APPENDICULARIID/E 



Chamisso and Eysenhardt (i82oa,"^ 362) propose the genus Appen- 

 dicularia, with the monotype A. Hagcllum 1820, a new Artie species 

 taken in St. Lawrence Gulf [Bay], Bering Strait. They give no 

 generic diagnosis, but they print a short specific diagnosis and they 

 figure the species. 



As shown above (footnote 7), Mertens (1831a, 205-220) claims 

 to have found this same species {A. Uagelliim) in its type locality 

 (St. Lawrence Gulf [Bay], Bering Strait) and definitely to have 

 recognized it as A. tlagelliim; he deliberately renames the genus as 

 Oikopleura and the species as chamissonis. This species is the only 

 one he cites for Oikopleura, hence it is genotype both by renaming 

 and by monotypy. 



Accordingly, until it is proved that Mertens was wrong in con- 

 sidering the two animals identical, Oikopleura 1831 must be con-
