Distnbutiov.—li. senco.u was originally described f.-om the Buruett 

 River, Queensland, and I have examined several specimens from various 

 localities in south-eastern Queensland. It also extends over the whole 

 area drained by the Murray River system ; numerous specimens are in 

 the Australian Museum from various widely separated localities in 

 western New South Wales, while it luis also been recorded from Pyramid 

 Hill, Victoria, bv Ogilby, and from Lake Alexandrina, South Australia, 

 by Zietz. The species further occurs in tl.e coastal rivers of New South 

 Wales at least as far south as Sydney, and I i.ave collected many specimens 

 both in the Hastings River and in various tributaries of the Hawkesbury 

 near Sydney.
