simple trinomials for varieties of animals, and pointed out that, 

 besides geographical races, there were several other kinds of 

 variation which might be designated by prefixing letters to the third 

 name. With regard to ambiguous names, of which Mr. Sclater 

 gave Lepus timidus as an example, he was of opinion that Linnseus 

 meant to include both the Mountain Hare of Norway and the 

 Common Hare under this name, and he thought that Lepus timidus 

 could be retained for the latter, without causing confusion. 



Dr. H. 0. PoEBES thought that if objection were taken to tauto- 

 nyms — which were but the logical result of the law of priority — 

 the genenc and not the specific name ought to be changed. The 

 generic portion of a name was liable to change at any time with 

 the increase of our knowledge, and it was evident that, if it became 

 necessary to place the species in some other genus, the law of 

 priority \vould demand the replacement of that name as its specific 

 designation. The result of this would be that, by change in the 

 specific part of a tautonym, there would be a constant liability to 

 change iu hoih parts of the appellation of a species. 



Mr. W P. KiEBY was of opinion that botanical names should not 

 knowingly be used again in Zoology, and remarked that the Germaii 

 Zoologists were not practically unanimous on this question. He 

 was inclined to think that the 10th edition of the ' Systema Naturae ' 

 was the most logical one to follow. He stated tliat when preparing 

 his ' Synonymic Catalogue of Diurnal Lepidoptera,' the idea had 

 occurred to him of making Doubleday and Westwood's ' Genera ' 

 his starting-point for nomenclature, but he had found this im- 

 practicable, and was consequently obliged to revert to the strict 

 law of priority.
