Summary. — The Secretary is authorized and instructed to insist that cases 

 presented for opinion shall be accompanied by reasonably complete data to 

 enable fair consideration of the points at issue. Pyrosoma 1804 has priority 

 over Monophora 1804. Cyclosalpa 1827 is not invalidated by Holothuria 1758 

 (type physalis), which does, however, invalidate Physalia 1801. The present 

 use of Holothuria (type tubulosa) in echinoderms is not in accord with the 

 Rules, but authors are advised to use Physalia 1801 for the Portuguese Man of 

 War, and Holothuria 1791 as genus of Sea Cucumber, pending action upon 

 possible suspension of the Rules in these two cases. As presentation of the 

 cases of Salpa, Appendicularia, Doliolum, and Fritillaria is incomplete and 

 contains errors, these cases are laid upon the table indefinitely, but without 

 prejudice; unless it can be shown that an application of the Rules in these 

 cases will result in greater confusion than uniformity, the Rules should be 

 enforced. 



Statement of case. — The following names were submitted to the 

 Commission by 12 special workers in the Tunicafa, with request that 

 the names be protected against change : 



Doliolum, Pyrosoma, Salpa, Cyclosalpa, Appendicularia, und Fritillaria 

 sind gegen Aenderung zu stiitzen.
