Exhibit Evening’ and Lecture by Prof. T. Harvey John- 
ston, M.A., D.Sc., March 18th.-- -Ten new membei's wei‘e nomi- 
nated. The vari('d exhibits filled the accommodation pro- 
vided. The Chairman (J^rofessor J. B. Cleland, M.D.') 
referred to the receipt of the Tepixe]* Collection and of a 
number of parcels of plants for the new herbarium, including 
one ]iew species of Lepidium fx*om. Bii'dsville. 
The President rejjorted that the Director of the Botanic 
Cardens (Mr. Bailey) was starting a special section foi* native 
plants, and Avoidd be glad to supply members with seeds for 
experimental cultivation. Mr. Hogan, of Morialta, also 
offered to help members to test native seeds undei* cultivation. 
Mr. J. F. Bailey exhibited a large cone fi*om a bunya- 
bunya tree {Araucaria Bidwillii), weighing 11 lb. 
Mr. E. H. Ising shoAved a specimen of the hyacinth orchid 
{Dipodium punctahcm), a Avhite everlasting {Ixodia acJiille- 
aides), the hop goodenia {Goodenia ovata), and a wattle {Aca- 
cia priiinosa), the leaves of Avhich close ixp at night. 
Dr. (Teland shoAved a specimen of a poisonous fungus now 
recorded (for the first time in South Australia) from Aid- 
gate. The same exhibitor also shoAAmd a specimen of a pretty 
but pernicious grass {Pennisetum villosus), now spreading 
in the neighborhood of Adelaide, and likely to prove very 
troublesome in pastures. Tt is said to have been introduced 
Prom Abyssinia. Di'. Cleland also shoAved specimens of the 
‘‘stable fly’’ and (explained in AAhat AAmys it differed from the 
“house fly.” 
Professor T. Harvey Johnston then spoke on a fcAv of 
the many forms of life brought up by the dredges on the pre- 
vious Saturday. 
A parasitic gastropod mollusc (Lamellaria sp.) taken 
from inside an Ascidian, proved to be the first specimen taken 
in South Australian Avaters. A point of interest is that 
though the animal had become an internal parasite, it still 
retained its eyes. Several interesting species of Holothurians 
Avere taken. These are generally sausage shaped bodies Avith 
Avarty skins and are related to the Bechc-de-Mer or Tropang 
of commerce. Some species eject their interior organs Avhen 
captured, and one specimen w\]\ fill a bucket with its sticky 
Avhite thread-like intestinal organs. These “cotton spinners” 
are a great nuisance in dredging.
