NOTES ON AUSTRALIAN CHAETOGNATHA. By Pbofessoe T. Harvey Johnston-, M.A., D.Sc, and B. Bfcklaxd Taylor (Biology Department, University, Brisbane.) (Text -figures 1-4.) {Bead before the Royal Societi/ of Queenslan/l, 2stii April, 191!)). The Chaetognatha of the Australian coast have received very little attention. Apart from the collection made in Shark Bay, Western Australia, reported on by Ritter-Zahony (1910). no systematic attempt to investigate them seems to have heen made. Xo records have been published regarding their -pre-sence on the northern and southern coasts, though several species, viz., Sagitta hexaptera, S. serratodeniata and EukroJrnia liamata have been reported from Antarctic waters due south of Australia (Fowler, 1907). A few casual determinations of species from the Eastern coast have been made by Ritter-Zahony in 1909 (S. bipunctata, S. serrato-deniata and S. robusta), and Johnston in 1909 (S. australis). Whitelegge (1889. p. 163) mentioned the occurrence of Sagitta sp. in Sydney Harbour, while Waite* reported that Sagitta was taken commonly in tow nets by the Thetis Expedition off the N.S.W. coast. Steinhaus recorded S. enflata from 160° E, some distance westward of Xew Caledonia, but the record cannot be considered as Australian. Ritter-Zahony (1909 p. 792) referred to the * E. R. Waite, Memoirs Austr. Museum, 4(1), 1899, p. 14.
