NO. 7 OPINIONS 115 TO 123 19 



Discussion. — By Conmiissioner Bather : 



The name Lithostrotion in the sense proposed by the writers is so commonly 

 used in textbooks as well as in scientific papers that stability of nomenclature 

 is more likely to be attained by suspending the rules in this instance than by 

 enforcing them. I therefore commend the proposal that L. striatum be fixed as 

 genotype of Lithostrotion to the favorable consideration of the International 

 Commission on Zoological Nomenclature. 



The papers in this case have been submitted to Dr. T. Wayland 

 Vaughan, and his reply is appended herewith for the information of 

 the Commission and as a part of the Opinion: 



I have received your letter of January 5 and the papers relative to recognition 

 of Lithostrotion striatum as the genolectotype of Lithostrotion. I am not able 

 to check all of the references given by Mr. Lang but I can check his reference to 

 Edwards and Haime's British Fossil Corals. I am convinced that the presen- 

 tation of Messrs. Lang and Stanley Smith is in all respects correct. Unless 

 there is some urgent reason not known to me I incline to agree with the recom- 

 mendation of Messrs. Lang, Smith, and Bather. I think that you know the 

 standing of these three men. It is very high and Doctor Bather is one of the 

 most distinguished paleontologists living. If their recommendation is not adopted 

 the name Lithostrotion will have to replace Lonsdaleia McCoy, 1849, which 

 would be unfortunate. I don't like to express a positive opinion until I am 

 entirely sure that I have considered all of the different angles, but I am not 

 inclined to make any opposition to the recommendation you have referred to me.
