LIST OF ZOOLOGICAL NAMES" 



1. The international committee invited by 

 the secretary of the International Commission 

 on Zoological Nomenclature to make a detailed 

 study of the nomenclature of ticks (Ixodoidea) 

 and consisting of the following specialists in 

 this group, W. Donitz (Berlin), Albert Hassall 

 (Washington), L. G. Neumann (Toulouse), 

 G. H. F. Nuttall (Cambridge) and Cecil War- 

 burton (London), has submitted its first report. 



2. Said committee unanimously agrees that 

 the following eight generic names are the cor- 

 rect names for the genera in question, and that 

 the correct genotypes, according to the Inter- 

 national Eules of Zoological Nomenclature, 

 are the species cited: 



Amblyomma Koch, 1844a, 223-231, type cajen- 

 nense Fabrieius, 1787. 



Argas Latreille, 1796a., 178, type reflexus Fabri- 

 eius, 1794. 



Dermacentor Koch, 1844a, 235-237, type reticu- 

 latus Fabrieius, 1794. 



Scemaphysalis Koch, 1844a, 237, type conoinna 

 Koch. 



Hyalomma Soch, 1844a, 220-223, type cegyptium 

 Linna3us. 



Ixodes Latreille, 1796o, 179, type ricinus Lin- 

 naeus. 



Mhipicentor Nuttall & Warburton, 1908, 398, type 

 iicornis Nuttall & Warburton. 



BMpicephalus Koch, 1844a, 238, 239, type «a?i- 

 guineus Latreille. 



3. Notice is hereby given that the under- 

 signed will wait until July 1, 1912, for any 

 zoologist to raise any objection to any part of 

 the report of the special committee. If no 

 valid point is raised by the date mentioned, the 

 undersigned will transmit the list to the Inter- 

 national Commission with the motion that 

 these names be incorporated in the " Official
