INTRODrCTIOJT. XXXV 



Their northern limit corresponds very closely to the isothermal of 

 55°. A specimen of Nyctinomus cestonii in the British Museum is 

 said to have been sent from Jersey ; but this is not quite certain, the 

 highest northern locality in Europe from which it has hitherto been 

 recorded being Switzerland, and in Asia, Amoy. Nyctinomus brasi- 

 liensis extends to Port Lucas in California, and to Charleston in 

 South Carolina. In the Southern Hemisphere Mysiacina tuherculata 

 occurs in New Zealand. 



Among the remaining families which are limited either to the 

 Eastern or Western Hemispheres, the Bhinolophidce have the highest 

 northern and southern range, two species extending into Southern 

 England, Northern Germany, and Japan, and southwards to the 

 Cape of Good Hope. The Pleropodidce, Nycteridce, and Phyllostomidce 

 scarcely extend beyond the tropical zones in both hemispheres. 



In bringing this Introduction to a close, T take the opportunity 

 of acknowledging the very liberal manner in which I was permitted 

 to examine the valuable collections of the Leyden, Paris, Berlin, 

 and Stuttgart Museums, respectively under the care of Professors 

 Schlegel, Milne-Edwards, Peters, and Krauss, to whom my especial 

 thanks are due. At Leyden, Dr. Jentink very kindly personally as- 

 sisted me when examining the unequalled collection of Pterojiodidce ; 

 and at Berlin I had the great advantage of seeing the many rare 

 specimens of species described and noticed in the valuable papers 

 published during the past twenty-four years by Prof. Peters, to 

 whom we owe the first attempt to arrange scientifically many of 

 the genera of Chiroptera, more especially those of the leaf-nosed 

 Bats of both hemispheres. At Berlin also, through the great 

 liberality of Prof. Peters, I had the privilege of inspecting the 

 beautifully executed series of unpublished plates representing the 

 species of Chiroptera in the collection of the Boyal Zoological 

 Museum and other rare species. 



Among many friends who have kindly assisted me by the loan 

 of specimens, I am especially indebted to Mr. E. R. Alston, Dr. J. 

 Anderson, Mr. C. Barron, Mr. W. T. Blanford, Mr. J. A. Clarke, 

 Prof. W. H. Flower, Prof. A. H. Garrod, Messrs. Godman and Salvin, 

 Colonel H. H. Godwin- Austen, Dr. P. L. Sclater, Mr. R. B. Sharpe, 

 Eev. S. J. Whitmee, Mr. J. Wood-Mason, and to Drs. J. J. Lamprey 

 and T. W. Wright, of the Army Medical Department, who sent 

 me several valuable specimens collected by them on the West coast 

 of Africa.
