In the original description I have placed this fish under 

 PCotosus, which have eight barbels. The absence of the sec- 

 ond dorsal fin would necessitate its removal to the genus 

 Neosilurus, with only six barbels. The Central Australian 

 form has eight barbels. For this reason I would suggest to 

 unite this species with Neosilurus, and to divide this genus 

 into two groups : — 



fa) Species with six barbels — Neosilurus hyrtlii, Steind., 



and .V. australis. Cast. 

 (bj Species with eight barbels — N. argenteus, Zietz. 

 This would avoid the creation of a new genus for 

 the Finke River and Cooper Creek fish.
