388 NOTES AND EXHIBITS. 



Mr. Macleay also exhibited a specimen of Strojjhura spinigera, 

 Gray, a small lizard found in the pine scrubs of the interior, and 

 reputed to be venomous. When irritated it ejects from pores in 

 the tail, an acrid fluid, which, immediately on exposure to the air, 

 becomes viscid. 



Mr. Brazier, for Mr. J. F. Bailey, of Victoria, exhibited a 

 specimen of Bulimus acutus, Muller, taken July 22, in a garden 

 at Collingwood. This species has been introduced from France. 



Mr. Fletcher exhibited specimens of a parasitic worm, Filaria 

 macropi majoris, or F. Websteri according to Cobbold, which is 

 often to be met with inclosed in cysts about the distal end of the 

 thio-h bone, sometimes extending some way down the shank bone. 

 Out of thirteen specimens, three males and one female shewed 

 these parasites. They are referred to in Vol. n, page 293 of Dr. 

 Bennett's Wanderings in N.S.W. So far they do not seem to 

 have been met with in any species of kangaroo but M. Major. 



Professor Stephens exhibited a block of tertiary limestone, 

 picked up at Belmont, Lake Macquarie, but in all probability 

 brought from the Southern Coast of Victoria or South Australia. 

 It was composed almost entirely of shells and fragments of shells, 

 some of which were but imperfectly mineralized. Bryozoa of two 

 or three kinds were also distinguishable. 



Also a piece of sandstone, composed directly from the debris 

 of a granite rock, found in the same place, but evidently not in 

 its original locality. 



Also a chert flake, resembling exactly a Paleolithic imple- 

 ment, but probably not a century old. From Coal Point, Lake 

 Macquarie. 



Also some specimens of silicious sinter, obtained by H. R. 

 Labatt, Esq., from the gorge of the Cataract River, a few miles 

 beyond Appin. There was a large quantity of this mineral 

 encrusting the rocks at a considerable height above the river bed. 

 It is evidently the deposit from the waters of a hot spring charged 

 with silicious matter, and derived probably from the great 

 mass of basalt which lies about the head of this river. There is 

 also, however, a very long and occasionally wide dyke of the same
