its characters agrees with the Phalangers, but it possesses the greatly enlarged 

 and grooved premolars of the Rat-Kangaroos; and not only does it show 

 evidence of a group which fills the only remaining gap between the Kanga- 

 roos and the Phalangers, but as a Phalanger with the posterior premolars 

 enormously enlarged it comes nearer to Thylacoleo than does any extint or 

 living form hitherto discovered. The conclusions arrived at are — That Thyla- 

 coleo is descended from a Phalangeroid form not very dissimilar from ß^n-awys, 

 and that it was almost certainly a purely carnivorous animal. — (3) Descri- 

 ptions of new A.ustralian Lepidoptera; with a Note on the Occurrence of 

 Dellephila livortiica, Esp., at Broken Hill, N.S.W. By Oswald Lower. 

 Eighteen species referable to the families Moiiocteniadae, Geometridae, Tortri- 

 cidae^ Gelechiadae^ and Oecophoridae^ are described as new. The beautiful 

 Sphingid, Deilephila livornica^ Esp., was noticed by the author to be common, 

 during the early part of March last, at the electric lights at Broken Hill. On 

 one occasion individuals were literally swarming. The species occurs in 

 Europe, Africa, and S, Asia. It was first recorded from Australia by Mr. 

 Miskin from a Queensland specimen. It is also known from Adelaide, but 

 has not yet been reported from Victoria, Tasmania, or West Australia; 

 nor has it been recorded previously from New South Wales. — (4) Botanical. 

 — Mr. Hedley exhibited a specimen of fully developed Gundlachia 

 recently taken by Mr. H. Leighton Kesteven from a pool in the Botanical 

 Gardens, Sydney. This is the second instance of its occurrence in Australia, 

 and the first in New South Wales. The genus has been treated of at some 

 length in Vol. viii. {2nd Series) of the Society's Proceedings. Possibly 

 no real Ancylns exists in Australia, and all those hitherto reported will 

 ultimately be shown to assume occasionally and at rare intervals the 

 Gundlachia form. Also photographs forwarded by Mr. Alex Morton, F.L.S., 

 Curator of the Tasmanian Museum, of a gigantic fish-hook almost identical 

 with that described in the last Volume of the Proceedings. The original 

 was collected near Membare in British New Guinea by the surgeon of H. M.S. 

 Wallaroo. — Mr. Froggatt exhibited a series of fruit-flies [Tephritis Tryoni, 

 Froggatt, the Queensland Fruit-fly, Halter ophor a capitata^ Wied., the European 

 Fruit-fly, and Trypeta sp.), all of which had been bred out of fruit obtained 

 in the neighbourhood of Sydney. Also samples of apple showing how the 

 San José Scale {Aspidtolus perniciosus, Comst.) discolours the fruit wich it 

 attacks. — Mr. Ogilby exhibited the type of the new bathybial fish from 

 Lore Howe Island described in his paper as Aethoprora perspicillata, and 

 remarked that it may be distinguished from the three Atlantic species by the 

 presence of a pair of supernumerary photophores between the upper angle of 

 the eye and the anteorbital. — Mr. Brazier exhibited a monstrosity of 

 Placostylus ßhratus, Martyn, from New Caledonia, the spire of which is drawn 

 out so as to give it the appearance of a Scala] it was collected by the late 

 Mr. George Thomas Rossiter and is from his collection. Also a variety 

 (three specimens) of Risella plana, Quoy, from Port Jackson, full and crenu- 

 lated at the sutures, 2 mm. wide all round, —
