SILURUS (PARASILURUS) ARISTOTELIS. 59 



On page 333, he gives the name Glanis Aristotelis, with- 

 out a description. To complete the history of this fish 

 we should have to include the references of Aelian, Ath- 

 enaeus, Pliny and subsequent writers who have depended 

 on the great Grecian author for their information. Though 

 the species is allied to the >Silurus glanis of Linne, it falls 

 into a different division of the genus on account of the 

 smaller number of barbels. It pertains to the group to 

 which Bleeker gave the name Parasilurus, the members 

 of which have but four barbels. The distribution of Pa- 

 rasilimis is thus shown to extend from the Adriatic across 

 the entire southern part of Asia, and from the Caspian 

 southward.
