.'Poiamogeton oltusifolius, HeUchrysum ruticlolepis, and Foten- 

 tiUa anserina. This last is said to be found only in this imme- 

 ^diate locality. Mr. Tepper was fortunate to discover Raloragis 

 Jieterophylla, distinguished by its digitate leaves. The tall 

 shrubs by the riverside — Biirsaria spmosa, Leptospermum 

 lanigermn, and Acacia retinodes — -were in full flower. Lytliricm 

 salicaria, with its purple flowers, was also gathered. 



Of the sedges collected, the most noteworthy were Cyperus 

 lucidus, C. iextilis, Juncus plaiiifolias, J. prismatocarpus, J. 

 xacBSpititius, and Scirpus inundatus. Of grasses, the tall Poa 

 caespitosa was found in fruit, together with Echinopogon ovatus 

 a,nd Eragrostis Brownii, and Ehrharta stipoides. On the rail- 

 way line Hcemarthria compressa was seen in flower, and varie- 

 ties of the aquatic plant, Triglochin procera, were in full 

 fruit. 



The party followed the Onkaparinga as far as the railway 

 bridge, and then returned to the station, which was left at 

 4.45, the city being reached shortly after 6 o'clock. 



PorRTH ExcuEsiON — Satfedat, Feb. 14, 1885. — Largs Bat. 



The members assembled at the North-terrace Eailway Station 

 .at a later hour than usual, and proceeded to Largs Bay. On 

 arrival there Mr. J. Gr. 0. Tepper presided over a business 

 meeting, at which two new members were elected. He then 

 introduced Mr. W. T. Bednall, who had consented to act as 

 leader. 



Mr. Bednall explained that the weather had scarcely been 

 conducive to the chance of finding many good marine specimens, 

 but by careful search the members might add something valu- 

 able to their collections. He pointed out that the Venus scala- 

 rina (the common cockle) was the predominant shell in this 

 locality, its distribution being very local and confined from 

 Largs Bay to about a mile south of the Semaphore. From there 

 southwards this shell was replaced by another sand-living bi- 

 valve, the Mactra polita, only a very few specimens of which 

 were taken. Mr. Bednall then suggested a number of other 

 epecies of shells that might be found ; but, as he intimated at 

 first, the result of the searching was not particularly inter- 

 esting. 



After being advised to collect the sand and small shells 

 which would be found in little heaps, and to dry it for exami- 

 nation under the microscope, when there would probably be 

 discovered beautiful specimens of small shells, diatoms, f oram- 

 inifera, and corallines, the party took a northerly direction 

 alone: the beach.
