^FAMILY TROCHIDAE, 
Cantharxdus, 
Quite a number of species of this pretty little shell live in 
our waters. 
C. exwinis. Some beautiful specimens have been collected recent- 
ly at Middleton and Port Willunga up to 30 mm. in length. 
The lovely greenish sheen of the interior is always attrac- 
tive to the collector, and when treated with acid, the ex- 
terior rivals the interior. 
C. apichms, was recently collected in numbers at Port Willunga. 
This specimen has a distinctive beauty, and when viewed 
in certain light, shines like a lovely jewel among the 
general beach debris. 
C. belhduSy C. conica and C, xnsodontes are all common on our 
Gulf beaches, each having certain handsome features. 
C. fasciaUis is also plentiful. The ocean beaches seem to produce 
a greater quantity and variety of colors than the compara- 
tively quiet Gulf waters, where the shell is usually smaller 
and less variable. 
Monodonta. 
M. coustricta, the common winkle, is well known on all our rocky 
shores, exposed at low tide. This plain mollusc has its 
compensation In providing the finder with a tasty dish. 
M. concamerata seem to have a preference for the less exposed 
cracks and crevices in the rocks, unlike the previous speci- 
men, which is not particular in that respect. 
M. adelaidae (formerly Dilonia) i& very plentiful on certain 
beaches,. This shell Is more finely sculptured than M, 
concamerata, and smaller. It has a pretty, greenish interior 
sheen. F. Trigg, Hon. Sec., Shell Club. 
EXCURSION TO MYLOR TYPE ORCHARD, 
MARCH 20, 1926. 
A large party under the guidance of the Director of the 
Adelaide Botanic Garden (Mr. J. Bailey) who has charge of the 
orchard visited Mylor. The drive through the hills was delightful. 
Near the orchard the candlebark {Eucalyptus rnbida) was greatly 
admired, its stately white bole showing out well against a back- 
ground of darker trees. 
The summer has been very dry and the fruit trees were not 
at their best but the members were greatly interested in examining 
a few of the 1600 varieties of apples under cultivation. 950 varie- 
ties of pears are grown and large numbers of other fruits are cul- 
tivated, including plums, peaches, apricots, cherries, persimmons 
and many others. The Remarkable Pine {P. radiata ~ P. insignis) 
has made splendid growth on a limited area of the orchard. 
The party were very much interested in the pruning and general 
treatment of many of the varieties of trees that came under their 
notice and a profitable afternoon was spent.
