Here again the principal difference seems to be in 

 the head. However, as two of these varieties are 

 known to the natives of Assam by different names, 

 there is reason to believe that they may really be dis- 

 tinct species. 



Dr. Gimther has given Barbus macrocephalus a 

 separate place in his Catalogue, but remarks that 

 it is at present a very doubtful species. The remainder 

 he has placed together under the name of Barbus mosal. 



Dr. Day considers Barbus mosal and putitora of 

 Buchanan, and macrocephalus of M'Clelland, to be one 

 species ; and B. tor, and B. progeneius, he describes- 

 as a separate species under the name of Barbus lor. 

 The difference between these two forms he states to 

 consist in the latter having a pointed snout, the lower 

 jaw being the shortest ; mouth somewhat deeply cleft, 

 lips thick and cartilaginous, with protruding lobes.
