The South Australian Naturalist. 



Excursion, 23/10/20. — Members of the Field Naturalists' 

 section of the Royal Society and of the South Australian 

 Aquarium Society made a visit to Jerusalem, under the leader- 

 ship of Messrs. E. Savage and H. M. Hale. Owing to the 

 extremely wet weather the party was small, but both societies 

 were represented. Mr. Savage drove the members to the Sanc- 

 tuary in his car, and as the rain ceased later in the afternoon 

 an enjoyable time was spent there. Amongst the botanical 

 specimens taken were some blooms of a fine Hakea (H. multi- 

 lineata). By means of dragnets operated from the banks in- 

 teresting aquatic material was obtained, including examples of 

 the little Blue-spot Cloby. This fish (Mugilogobius galwayi) 

 was comparatively recently described as new to science by Mr. 

 Edgar R. Waite, the President of the Aquarium Society. All 

 of the gobies netted were in remarkably good condition, owing 

 to the immense numbers of tiny crustaceans contained in the 

 shallow water. Quantities of Daphne — an excellent fish food — 

 were collected by the aquarists. The Daphne is a small crusta- 

 cean belonging to the group Cladocera, members of which pos- 

 sess a double carapace. It has but a single large eye, and swims 

 with the aid of one of its two pairs of antennae. 



The party afterwards adjourned to Mr. Savage's house. 

 Refreshments were provided by Mrs. Savage, following which 

 a hearty vote of thanks was accorded to the host and hostess. 



Excursion, 6/11/20.— The party visited Stoneyfell and 

 Slape's Gully. The leaders were Messrs. P. Runge and E. H. 

 Ising. The chief object of the excursion was to note the rocks 

 and minerals of the quarries there, but after giving some time 

 to this matter, attention was directed to the botanical specimens 

 collected by the party. 



WILD FLOWER SHOW. 



The first field naturalists' exhibition of native wild flowers 

 to be held on a large scale was held in the Institute Building, 

 North Terrace, on Friday and Saturday, October 8 and 9, 192o'. 

 Strictly speaking, this was not the first wild flower show in 

 connection with the section's activities, for a small show was 

 held in October, 1888, when Mr. \Y. H. Selway was Secretary. 



Professor F. Wood-Jones, of the Adelaide University, de- 

 clared the exhibition open. In his address, the Professor 

 strongly advocated the preservation and study of the native
