64 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 73 



nomenclatorial work based upon the principle advanced by Fol, it 

 is not at all impossible, though it is not yet clear, that the most far- 

 sighted course might perhaps be to suspend the Rules by validating 

 Oikopleura 1831, in spite of the fact that it is antedated by Ap- 

 pendicularia 1820, and at the same time to suppress Appendicularia 

 1872 in favor of Appcndiciila 191 5 in order not to admit nomencla- 

 torial practices of this nature. 



On basis of the foregoing data, the Secretary recommends that the 

 Commission adopt as its Opinion the following : 



(i) Appendicularia Chamisso and Eysenhardt, 1820, has priority 

 over Oikopleura Mertens, 1831. 



(2) Appendicularia Fol, 1874, is a homonym of Appendicularia 

 1820, and should be suppressed unless it can be shown that a strict 

 apphcation of the Rules will result in greater confusion than uni- 

 formity. If suppressed, the name Appendicula 191 5 is available as 

 substitute. 



(3) The contention of the Appellants that a change of the ordinal 

 [read family] name Appendiculari[i]dse is involved is not made 

 clear to the Commission in the premises contained in the presenta- 

 tion of the case. 



(4) See also proposition to table, page 69. 

 Opinion written by Stiles.

 Skinner, Stejneger, Stiles.
