‘ In the Kecords of the Australian Museum, vol. iii. p. 203, Waite armouuees the occui*rence 
of this species at Lord Howe Island, and claims it as ‘■‘an addition to the Australian fauna.”

same remarks apply to Brama raii and Cristiceps a'nstralis and in a lesser degree to (Jhlronemus 
niarmorntns anrl Trachinotio-i holla {rv>fscllii), wiiilo Pegasus draconis, also there recorded, is omitted 
wholly from his list.
