396 NOTES AND EXHIBITS. 



should have been stated that the type-specimens had been pre- 

 sented to the Australian Museum. 



Mr. A. R. McCulloch showed some drawings of fishes made 

 upon specially prepared paper, the use of which reduced the time 

 and labour otherwise necessary to produce similar results. 



Mr. A. A. Hamilton showed specimens, from the National 

 Herbarium, of Mesembryanthemum edule Linn., " Hottentot 

 Figs," a South African plant which (so far- as he knew) had not 

 not been recorded for New South Wales. The plant is growing 

 on Lady Robinson's Beach, associated with the indigenous M. 

 cequilaterale Haw. It is easily distinguished from the latter by 

 the larger leaves and fruits, and by having both yellow and 

 purple flowers on the same plant. It is recorded from Victoria 

 in E wart's "Weeds, Poison-Plants, and Naturalized Aliens"(p.82). 

 — Also a series of leaves taken from plants of Seuecio laulus 

 Forst., growing at Lady Robinson's Beach, showing variation 

 from entire to pinnatisect, from h an inch to G inches long, and 

 from under 1 line to nearly 1 inch broad. This particular form, 

 of a widely distributed and variable species, seems to have selected 

 the coastal sand-dunes as a habitat, no plants being seen more 

 than a few hundred yards inland. It was noted that the leaves 

 became more succulent as the plants approached the beach. 



Mr. E. Cheel exhibited specimens of an interesting lichen, 

 Parmeliopsis semiviridis (Nyl.) A. Zahlb., collected by Mr. D. 

 G. Stead, at the junction of McKeown's Creek and Duckmaloi 

 River. It was originally collected on rocks (Table Mt.) in Tas- 

 mania, by Robert Brown, (No. 525b), and recorded b}^ Crombie 

 [Journ. Linn. Soc, Bot., xvii., 1880, 397] under the name Chon- 

 dropsis semiviridis (F. Mull.), Nyl. See also Vict. Nat. iv., 95. 

 Baron F. von Mueller afterwards collected specimens on the 

 Murray River, and named them Parmelia semiviridis. This latter 

 name is recorded by Nylander in his " Enumeration generale des 

 Lichens, et leur distribution geogr. ' Parmelia hypoxantha Miill.-
