nical. — Mr. Froggatt exhibited leaves of a Banksia covered virith the hairy 

 tests of the larvae of an Homopterous insect of the family Aleyrodidae, the 

 remarkable white filaments forming a hairy coat over the leaves. — Mr. North 

 exhibited the skin of a fledgling Fan- tailed Cuckoo, Cacomantis flabelUformis^ 

 which he had caught on the 3rd instant in a gully at Chatswood. It was being 

 fed by its foster-parents, a pair of Rock Warblers, Origma rubricata, whose 

 nest was found in a dark recess in the rocks a few feet away. Usually the 

 egg or young of this parasite is found in domed nests built in situations 

 which are more or less exposed to the sun's rays. That it is not a solitary 

 instance of this Cuckoo depositing its egg in the nest of this gloom-loving 

 spec es is borne out by the fact that the same pair of Rock Warblers built 

 again in a rocky chamber about two hundred yards away from their previous 

 sneting site. On the 15th instant, and before the nest was quite finished, it 

 contained an egg of C. ßahelliformis^ and on the 25th instant two eggs of 

 0. rubricata^ all of which were slightly incubated. This set of eggs was also 

 exhibited. — Dr. Cox showed a fine specimen of, and communicated a Note 

 on, Voluta Bednalli^ Brazier, from Port Darwin, of which, as far as he knew, 

 the specimen exhibited was the third example known, though the species 

 was described in 1878. — Dr. Cox also contributed a Note on Thersites 

 pachystyla, Pfr., var. subfusco-zoiiata, var. nov., from Queensland; and he 

 exhibited an illustrative series of specimens, adult and young. — Dr. Cox 

 also exhibited very fine specimens of what he looked upon as varieties of 

 Thersites bipartita^ Férussac, smaller than typical specimens, with the base 

 very dark, and with a very dark, rather narrow band running parallel with 

 the suture, the lip of the shell also inclined to a carnelian-pink. These 

 specimens'' înight lead ofi" to what had been described as Thersites Beddomei, 

 Braz., but the shell in question was found with larger specimens which 

 gradually passed into the typical form. To illustrate the genus a large typical 

 pair of T. bipartita were exhibited, with a pair of the same quite devoid of 

 a dark base or coloured suturai band; also a pair subangulate at the periphery 

 of the last whorl, from Cairns, and of large size; likewise a pair of the same 

 of smaller size, very much resembling in colour, &c., the smaller forms of 

 Nanina ovum from the Phillippine Islands ; and two pairs of a smaller variety, 

 and much more depressed than the type, which appeared to be referable to 

 T. Dunkieììsìs, Forbes ; also examples of T. semicastanea, and of T. Bellenden 

 -kerensis. — Mr. Rainbow exhibited specimens of two interesting spiders from 

 the neighbourhood of Sydney, one [Ariamnus ßagelhim^ Dolesch.) a long 

 whip-like Theridion, the other [Leptorchestes striatipes ^ L. Koch) an ant- 

 resembling Attid; and he communicated a Note on their characteristics and 

 habits.
