NOTES AND EXHIBITS. 



Mr. F. H. Taylor exhibited specimens of Lucilia fucina Walker, Neopollenia 

 papua Walk., — both recorded for the first time from Australia, the former being 

 originally described from S. Africa, the latter from Papua. L. fucina is one of 

 the sheep maggot-flies in Queensland, and probably in other States, and seems 

 to have been confused with L. sericata. — CJiri/som/jia rnfifacies (Macq), C. varipes 

 (Macq.), and Ophyra analis Macq., also sheep pests, C. dux Esch., Lucilia solain 

 Walk., PyreUia naronea Walk., and Chaetodacus tryoni (Frogg.), a fruit fly 

 which breeds in grenadillas in North Queensland; also Binellia tayloriana Bezzi 

 and Euprosopia piinctifaeies Bezzi. 



Mr. E . Cheel exhibited specimens taken in October last, from a cultivated 

 plant of a so-called double flowering peach-tree (Pruniis persica var. dianthiflora) 

 showing, in addition to the ordinary flowers with an increased number of sepals 

 and corresponding number of petals and single pistils, quite a number of flowers 

 with two, three and four carpels distinct from the calyx and from each other in 

 the one flower. An illustration, together with a note, is published by M. J. 

 Berkeley in the Gardener's Chronicle for 18.52, p. 452, of a similar occurrence in 

 a "Golden Drop Plum," but the number of carpels according to the drawing was 

 usually two, or occasionally three, in the one flower. Kemer and Oliver ("Vol. 

 ii., p. 548) refer to this peculiar growth under the term "Antholysis," whilst 

 Berkeley's drawing and note is quoted by Masters (Teratology, p. 365, fig. 186), 

 under the term Polyphylly of the flower. Worsdell (The Principles of Plant 

 Teratology, vol. 2, p. 93, 1916) mentions that in dovible flowers of the cherry, two 

 carpels are almost invariably present. Daydon Jackson defines the term "Antho- 

 lysis" as a loosening or a retrograde metamorphosis of a flower. 



Mr. A. R. McCulloch exhibited a small collection of fishes recently presented 

 to the Australian Museum by Mr. David G. Stead, general manager of the State 

 Trawling Industry. These had been trawled in 150 fathoms, East of Sydney, on 

 the edge of the continental shelf, and included several species not hithei-to recorded 

 from New South Wales waters.
