Notice of Possible Suspension of the ‘Rules of Nomenclature in the 
Cases of Holothuria, 1758, vs. Physalia, 1801, and Bohadschia, 
1833, vs. Holothuria, 1791. 
In accordance with the requirements prescribed by the International 
Congress of Zoology, notice to the zoological profession is hereby 
given that on or about October 1, 1917, the undersigned proposes 
to recommend to the International Commission on Zoological 
Nomenclature that the Rules be suspended in the following cases :— 
Holothuria, Linn., 1758 (type physalis), vs. Physalia, Lamarck, 
1801 (type pelagica). The effect of suspension will be to retain 
Physalia as generic name for the Portuguese Man of War. ~ 
Bohadschia, Jaeger, 1833, vs. Holothuria, Bruguiére, 1791. The 
effect of the suspension will be to retain Holothuria for the Sea 
Cucumbers. 
The motion for suspension includes the following points :— 
(1) Suspend the Rules in the case of the generic names in 
question ; 
(2) Permanently reject Holothuria, 1758, type physalis ; 
(3) Validate Physalia, 1801, type pelagica (syn. physalis, 1758) ; 
(4) Accept Holothuria as dating from Bruguiére, 1791, despite 
the existence of Holothuria, 1758 (if rejected) ; 
(5) Said suspension is not to be construed as invalidating any 
specific name. 
The grounds advanced for suspension will be :— 
(a) A strict application of the Rules in these cases will result in 
greater confusion than uniformity, because ‘ 
(6) The cases involve a transfer of generic names, almost 
universally accepted in the sense given above since 1791 (for 
Holothuria) and since 1801 (for Physalia), t6 genera in other 
groups in connection with which they have been used by only a 
very few authors during more than 100 years. 
The undersigned cordially invites zoologists to communicate, not 
later than September 1, 1917, to him or to any other member of 
the Commission, either their approval or disapproval of the 
proposed action. 
C. W. Srizzs, 
Secretary to Commission.
