tata, Cambr., both in general appearance, colours and markings, and in 

 respect of its abdomen, A. speirae, Simon. All the spiders of this genus are 

 remarkable for their brilliancy, and many of them, when suspended in their 

 webs, look like atoms of burnished silver, or dew-drops glistening in the 

 sun. In habits they are parasitic, and usually construct their irregular webs 

 among the outer lines of the snares of the larger orb-weavers. Their food 

 consists of the smaller insects that have become entangled in the huge orb- 

 like, webs, and which are too minute to attract the attention of the legitimate 

 tenant. The specimen obtained by me had established itself at the lower 

 edge of a web occupied by a huge Nephila ventricosa^ Rainbow. — Mr. W, 

 S. Dun exhibited two fossils shells from the Narrabeen Beds, near Newport. 

 One, collected by Mr. W. Willcox, belongs to one of the extreme genera of 

 the fossil Uiiionidae, occurring in the newer Palaeozoic and older Mesozoic 

 Rocks. The left valve only is preserved, and is somewhat distorted. It is 

 13 mm long and 8 broad. The beak is sub-terminal, shell thin, concentric 

 lines of growth very apparent, hinge-line long and straight. The umbo does 

 not project much. From the Anthracomyae it differs mainly in point of size, 

 and approaches in outline some of the species with subcentral beaks. The 

 general similitude to Naiadites, Dawson, is much stronger, as is shown by 

 comparison with some of the figures given by Dr. Wheelton Hind (Mon. 

 Carhonicola, Anthracomya^ and Naiadites Pt. 2, 1895, t. 17, IF. 35-38 — iV^. 

 triangularis — and t. 18, f. 34 — N. elongata). It is impossible, in the 

 absence of the hinge structure, to say definitely to which genus this form 

 belongs. The other specimen is very indistinct and much crushed, 20 mm 

 long, 9 broad. Beak central, shell apparently thin, with strong concentric 

 ridging. This form was found by Mr. W. Martin, and is most probably a 

 Vnio. — Mr. Palmer exhibited branches of an Ulmus from his garden at 

 Lawson, which had been killed by the borings of the larvae of a Longicorn 

 (probably a species of Monohammus). Also an undetermined fungus growing 

 abundantly round the roots of Eucalypts, which is eaten with avidity by cows.
