36 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 73 



The point was also raised in regard to the general advisability of 

 including in the list the original type localities of certain type species 

 as published by the original authors. 



Discussion. — The Secretary feels very strongly on the point that 

 at the present moment the Commission should show preference to 

 cases which can be agreed upon by unanimous consent, and that 

 so far as possible, it seems wise to postpone consideration of names 

 that may be questioned from any point of view whatsoever, until the 

 world conditions become more settled. 



In accordance with this policy, three of the names in question, 

 namely, Doris, Elephas, and Equus, have been tabled temporarily 

 and without prejudice, and the original type localities have been 

 omitted from the list. 



After elimination of the three names and the type localities just 

 referred to, there remain 27 generic names with genotypes, in regard 

 to which no objection, question, or criticism of any kind has been 

 raised. 



The Secretary has verified personally all the references given 

 below, and so far as evidence is available it appears that these 27 

 generic names are nomenclatorially available and valid under the 

 Code, and that the type designations given are in accord with the 

 Rules. The only question which it seems possible to raise in respect 

 to these type designations is the point whether certain of them are 

 type by subsequent designation, or type by absolute tautonymy ; 

 whichever method is followed the end result remains the same. 



Upon basis of the foregoing premises, the Secretary recommends 

 that the following 27 generic names, as definitely fixed by the type 

 species mentioned, be adopted in the Official List of Zoological Names.
