SOME FISHES FROM BORNEO. 



BY HENRY W. FOWLER. 



The Wistar Institute of Anatomy of Philadelphia has'received valu- 

 able collections of fishes from Borneo, principally from the Baram region 

 of Sarawak, or Brunei as given on some maps, in the British possessions. 

 The larger collections were made by Dr. William H. Furness, 3rd, of 

 Philadelphia, in 1898. They are all from the Baram basin. Previously 

 Mr. Alfred C. Harrison, Jr., and Dr. H. ]\I. Hiller had also obtained ma- 

 terial from the same region, together with some other from the Kapuas 

 river in western Dutch Borneo. 



The larger munber of forms are either fluviatile or fresh-water and 

 interesting on account of their apparent rarity. In order to facilitate 

 satisfactory comparisons I have tried to give more or less complete 

 accounts of these. Some others are represented by large series. 



Drs. Horace Jayne and M. J. Greenman kindly submitted the col- 

 lections to me for examination. I have also to thank them for their 

 recommendation to the Institute of the services of the artist. Miss 

 Helen Winchester, who made the accompanying figures. As usual the 

 line with each represents an inch. 



To the Academy of Natural Sciences of Philadelphia I am under 

 obligations for many courtesies, such as the use of the library and collec- 

 tions. Among the latter are a number of Borneo fishes received from 

 the Paris Museum by Prof. E. D. Cope, and presented by him to the 

 Academy. As these form part of the collections of M. Chaper, reported 

 by Prof. Leon Vaillant in 1893, they are of value as authoritative deter- 

 minations. I beg to thank Prof. Vaillant for their verification. Dr. 

 Samuel G. Dixon, President of the Academy, Dr. Henry A. Pilsbry, 

 ■Mr. Witmer Stone and Mr. James A. G. Rehn have kindly given assist- 

 ance and many suggestions. 



For convenience it may be inferred that the material examined under 

 each species was obtained by Dr. Furness, unless otherwise stated,
