48 The South Australian Naturalist. 



the scarp of the Willunga Range, while to the south the eye 

 sees the forest-clad ranges stretching into the distance. A few 

 miles' run took the party past Myponga to the fortieth mile 

 post, where members of the Section, Mr. and Mrs. Page, had 

 kindly made provision for their reception. Later the party 

 wandered through the scrub, under the direction of Mr. and 

 Mrs. Page^ both of whom are ardent lovers of wild nature. 

 The party secured bunches of the native heath, Epacris im- 

 pressa, which was growing profusely through the scrub. The 

 orchids were, of course, scarce at this time of the year, but 

 Eriochilus fimbriatus, with its feather-edged tongue, and 

 Eriochilus autumnal is (known as ''parson's bands") were 

 taken. The former is rather rare, and the fcAv specimens seenr 

 were eagerly examined. Native honeysuckles (the handsome 

 Banksia ornata and B. marginata) were common, the flower 

 spikes of the former species bein^- particularly fine. Correa 

 speciosa was in bloom, its long tube flowers of contrasting red 

 and yellow being very conspicuous; its more retiring relative, 

 Correa aemula, with its green flowers, was found growing, as it 

 usually does, near the creek bed. Conospermum patens, Caly- ^j 

 thrix tetragona, and a Spyridium were also taken. Owing to I 

 the absence of the selected leaders, the Chairman of the Section 

 (Mr. W. Ham) addressed the members, pointing out some of 

 the most interesting features of the trip. The scenic beauty of 

 the steep scarp of the Willunga Range was contrasted with the 

 Avide valley to the north-west, through which the Onkaparinga 

 flowed in ancient times, before it changed its course to cut a 

 deep gorge through the Noarlunga Hills. Then came the 

 Archaeocyathinae limestone reef, forming such a prominent 

 feature in the Sellick's Hill, having been built up in the dawn 

 of the world's geological history by organisms somewhat resem- 

 bling the corals of modern tropic seas. Reference was also 

 made to the botanical Avealth of the Myponga scrub and to the 

 schemes put forth for the utilisation of the water supply of the 

 district. A most enjoyable time was spent by the members, 

 who were enthusiastic in their praises of the beauty of the scrub. 



A discovery of interest to the geologists of the party was 

 that of an outcrop of tertiary fossil rock containing polyzoa 

 corals, etc., occurring close to the road on the property of 

 Mr. Pa^e.
