OF THE A^HTR. 



By Leo Berg, 



Of the Zoological Muwum of the Iiiijjerial Academij of Scienrcii, Saint Petersburg. 



This paper contains a review of the Cobitithi? known to inhabit the 

 water S3\steni of the Amur River. It is based on material belonging 

 to the Zoological Museum of the Imperial Academy of Sciences at St. 

 Petersburg and duplicates in the United States National Museum.

After comparing- JL miguillicaudatu-s from East Asia with specimens 

 of Jf. /W/Z/.y from Europe (see table), I became convinced that they 

 are closely allied (as noticed already by Doctor Giinther.)^' The only 

 obvious distinguishing character is the color; in European and \^^est 

 Siberian specimens there are on the sides of the body longitudinal 

 bands, while in east Asiatic specimens the bands are substituted b}' 

 irregularh' distributed dark spots. Some specimens from Amur, as 

 regards the color, are intermediate between angtdllicaudatus and 

 fossllis. As the plastic characters are identical in both species, I 

 regard anguilUcaudatus as a subspecies oi fossllis.
