Presentation of case. — Circular Letter no. 26, dated April 29, 

 1916, contained a list of 30 generic names proposed for inclusion in 

 the Official List of Zoological Names. Said Circular Letter was 

 mailed to approximately 350 zoological institutions, laboratories, and 

 professional zoologists throughout the world, and 20 copies were sent 

 to each Commissioner for distribution in his own country. The 

 Circular Letter contained an invitation to all persons interested to 

 express their approval or disapproval of these names. All of the 

 names were published by Apstein in 191 5. The names of fishes have 

 been reported upon favorably by Commissioner Jordan, who has 

 studied them for the Commission. The names of the mammals have 

 been laid before the Advisory Committee on the Nomenclature of 

 Mammals ; the genotypes of the mammalian names agree with the 

 genotypes accepted by Palmer 1904. 



It would appear, therefore, that ample notification has been given 

 the zoological profession that these names would come before the 

 Commission for final vote. 



Seventy-five zoologists have responded to Circular Letter no. 26 ; 

 sixteen of these expressed approval of all of the names. Twenty- 

 six additional responses raised no objection and made no comment 

 on any of the names. In thirty-three instances only a portion of 

 Circular Letter no. 26 was returned to the Secretary, but no adverse 

 comment was made on any names in the rest of the list. 



In connection with 27 of the generic names in said Circular Letter, 

 no objection, question, or adverse comment of any kind whatsoever 

 has been raised. In connection with three names, namely, Doris, 

 ElepJias, and E quits, points have l)een raised which indicate the 

 advisability of again referring these three names to specialists in 

 the groups in question for further consideration.
