XXXII. — Additional Remarks oti the Classification of the 

 Genera of Chiroptera. By G. E. DoBSON, M.A., M.B., 

 F.L.S., &c. 



Since mj Conspectus of the Suborders, Families, and Genera 

 of Chiroptera was published in the ' Ann. & Mag. Nat. Hist.' 

 for Nov. 1875, the system of classification adopted by me has, 

 among other notices, been especially referred to in Mr. Wal- 

 lace's 'Geographical Distribution of Animals,' and in a review 

 of my ' Monograph of the Asiatic Chiroptera ' which appeared 

 in the last number of this journal. In both instances the 

 writers appear to regard my new families Emhallonuridoe. 

 and Nycteridce as equivalent to Noctilionidce^ Gri'S-Jj and Mega- 

 dermata, Peters, respectively. 



As it would necessarily follow, if these opinions were 

 accepted, that zoologists must consider the new names proposed 

 by me additions only to the already much overcrowded list 

 of synonyms, I think it very necessary to point out, to those 

 who may not have time or opportunity to compare my clas- 

 sification with those previously published, the differences which 

 exist between the natural families indicated by me under the 

 names Emhallonuridce and Nycteridce and those previously 

 known as Noctilionidce^ Gray, and Megadermata^ Peters, respec- 

 tively. 



In the Table below I have placed, for the purpose of com- 

 parison, the names of the genera composing the families Nyc- 

 teridce and Einhallonurid<e in parallel columns with those con- 

 taining the genera of Megadermata^ Brachyura and 3Iolossi, 

 Peters, and Noctilionidce, Gray.
