During the journey Mr, Topper explained that there was a 

 distinction between the submarine flowering plants and seaweed. 

 The plants Ci/modocea antarctica and Posidonia australis, found in 

 such large quantities on the beach, were commonly mistaken for 

 algcT (seaweed). The difference shown in the appearance of the 

 seaweed and the seaplant was very marked; but the distinction 

 in classification seemed to be rather finely drawn. A good 

 specimen of Halopliila ovalis (marine plant) and some others 

 were shown, but nothing worth mentioning was found in alg?e, 

 probably because the attention of the members seemed to be 

 confined to the shells. Yery few specimens were taken alive, 

 but a fairly good collection was made of Triton Quoyi, Nassa 

 fasciaia, Columhella Lincolnensis, Natica conica, Sigaretus 

 zonalis, Conns rutilus, Bittium turritella^ Mactra pura, JBLiatuJa 

 hiradiata, Area lima. Only broken specimens of JPecten aus- 

 f rails, P. hi/tons, and P. laticostatus could be obtained by such 

 a casual examination. Solemya australis was uncommonly 

 abundant, but small and in parts only. Phasianella hulimoides 

 (pheasant shell) was rather scarce. Mr. Molineux obtained 

 one of the latter alive, which he explained had, by the appear- 

 ance of the shell, evidently at some time been attacked by a 

 stingray, but eluded the enemy. The shell had been broken, 

 and had grown again with an additional patch on the outside, 

 which was not an infrequent occurrence. Much interest was 

 imparted to the excursion by little dissertations upon the 

 habits of land and marine life, in many cases a very complete 

 comparison being made.

The party arrived at Bridge «^ater about 2.30, where they 

 were met by Professor Tate, and started to walk down Cox's 

 Creek, along which they proceeded for about a mile. On the 

 way were seen the creeper Mariantlius hignoniaceus, and the 

 native fuchsia, Oorrea decumhens, with yellow as well as red 

 flowers. Along the banks of the creek was discovered the 

 handsome sedge, Cladium Mariscus. The blue-bell, Wahlenher- 

 gia gracilis, was found in abundance, and it was stated that this 

 plant had been exhibited at the Royal Agricultural Show as a 

 fodder-plant, whereas if not poisonous it was at least very un- 

 wholesome. Lohelia microsperma, which plant is stated to have 

 caused the death of much valuable stock, was noticed, as 

 was also the white everlasting, Ixodia achilleoides, a flower 

 peculiar to the Mount Lofty Eanges and the South-east Desert. 

 The bright Goodenia ovata was very plentiful. 



The party eventually arrived at a waterfall, the basin of 

 which is enclosed on three sides with his^h rocks. Professor
