Presentation of case. — The Secretary's Circular Letter No. 122 

 contained a list of 61 names suggested for inclusion in the Official 

 List of Generic Names. Practically all of these are in Commissioner 

 Apstein's (1915) list of Nomina Conservanda. The addition (jf 

 Lavcrania is made in order to meet a difference of o])inion among 

 specialists as to classification. 



The Secretary has personally checked these names and believes that 

 they are all nomenclatorially available and valid, and tliat, therefore, 

 they can be adopted in harmony with the Rules instead of as Nomina 

 Conservanda. He has changed the dates given by Commissioner 

 Apstein in several instances to agree with the dates found in Wash- 

 ington.
