NOTES AND EXHIBITS. 



Mr. Maiden exhibited (1) specimens of the new species of 

 Eucalyptus described in his paper. (2) A specimen of Acacia 

 leptoclada A. Cunn., from Howell, showing stem-fasciation, which 

 appears to be rare in the genus. And (3) a number of coloured 

 drawings of seedlings of various stages, from cotyledon leaves 

 to first leaves and first alternate leaves, in the genus Eucalyptus. 

 His plan is to sow seed from well-authenticated materials of 

 which herbarium specimens are preserved for reference. Under 

 his direction Miss Margaret Flockton had made about 200 

 drawings so far, and he had described the seedlings in detail, 

 somewhat on the lines of Lubbock's " Seedlings." The results 

 were very interesting, and brought out affinities between species, 

 some of which were perhaps unexpected, or, it may be, only guessed 

 at. He intended to increase the number of seedlings (all raised 

 in the Botanic Gardens, Sydney) very considerably before 

 submitting a monograph for publication. 



Mr. T. Steel exhibited very fine living examples of the follow- 

 in"- land planarians : — Geoplana Sugdeni, G. McJIahoni, and G. 

 sang^dnea, collected by Mr. H. W. Davey in Victoria. 



Mr. R. H. Cambage exhibited a good series of specimens of 

 irregularly cylindrical, more or less tubular, aggregations of 

 quartz (and shell) sand, cemented to a coherent mass with 

 carbonate of lime, from Barren] oey, where they are plentifully 

 distributed over a distance of 200-300 yards on the upper part 

 of the beach which separates Pittwater from the ocean. Many 

 are standing upright in the sand, about 6 inches high, as though 

 the incrustation had formed about the lower parts of plants, 

 before the sand had been denuded. Others were winding about 

 on the top of the sand, and were at once suggestive of root shapes. 

 These incrustations, which have a general resemblance to 

 fulcrurites, vary in diameter from f to | of an inch, and show a 

 pipe which, it is supposed, was originally occupied by a root.
