232 J. H. MAIDEN. 



Through the kindness of Dr. A. B. Rendle, F.R.S., of the 

 British Museum, I have : — 



(1) a photograph of the sheet of A. oncinocarpa in that 

 herbarium, bearing the label — "210. Sims' Island, A. Cun- 

 ningham, First Voyage of Mermaid, 1818." This was of 

 course Capt. P. P. King, R.N's. Voyage. Accompanying 

 this is part of a phyllode, an opened spike and an unopened 

 one. Sims' Island is a little island 33° 22' (Northern Terri- 

 tory) say a degree distant from the Liverpool River (see 

 below). 



(2) Two phyllodes and a fruit of "No. 236 Melville Is. 

 Leg. Fraser." Marked "portion of type." This is Northern 

 Territory, north of Darwin. 



Now we come to A. oligoneura F.v.M., Journ. Linn. Soc. 

 iii, 139 (1859). 



In this Journ. lt, 109, I go fully into the history of this 

 species, heading my enquiry "What is A. oligoneura 

 F.v.M.?" I now believe I can answer this question, having 

 compared authentic material of both species. It is a 

 synonym of the older A. oncinocarpa Benth. Mueller 

 figured neither species in his " Iconography of Acacias," 

 and I submit drawings which will make the combined 

 species quite clear. 



The two localities quoted in B. Fl. ii, 405, for A. oligo- 

 neura are Victoria River and Macadam Range, Arnhem 

 Land. See also the localities of the type, quoted by me, 

 this Journ. li, 110. All these are Northern Territory. 



The following specimens of A. oncinocarpa Benth. have 

 been labelled A. oligoneura F.v.M. at different times. 



1. "Liverpool River, W.A., B. Gulliver." (Liverpool 

 River is, however, in the Northern Territory, running into 

 the Arafura Sea near 134° B. Long, about intermediate 

 between Darwin and the Gulf of Carpentaria). This was
