the Williamstown excursion, said that the genus Ibla contained 

 only two species, both of which had been recorded from New 

 South Wales and South Australia, as well as Victoria. The 

 Life-history of the barnacles was very interesting from the fact 

 that from the egg is hatched a larval free-swimming form, 

 termed a nauplius, a small triangular body bearing three pairs 

 of limbs, thus showing its crustacean origin. This, on moulting, 

 assumes a cyprid form, afterwards attaching itself by the head 

 to a stone or fixed object and developing into a barnacle. It 

 lives a sedentary life, catching its food with its feet, which are 

 the beautiful plumed cirri seen waving from the shell of the 

 barnacle when living. 



Mr. F. Pitcher drew attention to his exhibit of three species 

 of Acacia at present displaying bloom in the Botanic Garden ; 

 these were tin- Narrow-leaved Acacia. Acacia linearis, Sims, 

 thr Sunshine Wattle, Acacia discolor, Willd., and the Itea-leaved 

 Acacia. Acacia iteaphylla, F. v. M. Also, portion of a flowering 

 branchlet ol the Queensland Fire-wheel Tree, Stenocarpus 

 sinuatus, Endl., which would serve to indicate the gorgeous 

 appearance the tree at present presented : and in reply to a 

 query said the Stenocarpus usually did well in cultivation. 



PAPERS READ. 



i. By Mr. F. Chapman, A.L.S.. " Notes on Foraminifera and 

 Ostracoda Found in a Sample of Sand at Williamstown Beach." 



The author referred to the special interest attaching to this 

 small collection of microzoa from some Williamstown sand 

 collected during tin' recenl Club excursion, and pointed out 

 the greal variety "I forms from so small a sample. They had 

 a wide distribution, both geographical and geological. The 

 shells were, generally speaking, rather starved or otherwise 

 diminutive, presumably because ol the ma^nesic-bearinfj; rocks 

 in the vicinity. From the ostracodal shells much useful dis- 

 tributional data could be gathered, and. although the deter- 

 minations had to be made on the empty valves, vet sumcienl 

 characters existed to enable one to recognize the various 

 ies, and by means ol blackboard sketches the principal 

 forms were demonsti ated. 



Mr. |. Gabriel said he would like to know whether the large 

 I Foraminifera found during the process ol boring for 

 coal at Altona Bay some years ago were still extanl in the 

 neighbourhood. Mr. I hapman replied in the affirmative.

The authoi said that, while examinin mi material col- 

 lected during the visil ol the ( lul> party to Mounl Baw-Baw 

 year, he came across an organism which, a1 firsl unlike an 

 amoeba, afterwards exhibited a characterise amoeboid move-
