SILUliUS (PARASILURUS) ARISTOTELIS. 59 
On p.'igc 333, he gives the name Glanis Ariatotelis, with- 
out a description. To complete the history of this fish 
we shonhl have to inchide the references of Aehan, Ath- 
enaeus, Pliny and subsequent writers who have dei)endcd 
on the great Grecian author for their information. Though 
the s[)ecies is allied to the iSilwiis glanis of Linne, it falls 
into a different division of the genus on account of the 
smaller immher of barbels. It pertains to the group to 
which Bleeker gave the name Parasilurus^ the members 
of which have Init four barbels. The distribution of Pa- 
rasiluruH is thus shown to extend from the Adriatic across 
the entire southern part of Asia, and from the Caspian 
southward.
