Mr. Pritchard said there were some other specimens 

 which he had obtained on a recent visit, and which were 

 very interesting. The first was a coral which Mr. Cresswell 

 had mentioned, namely, Heliolites. A large quantity of 

 this material had been obtained on the last visit, and was 

 in a very perfect state of preservation, so that it would be 

 a good specimen for description. There was another fossil 

 which occurred there rather commonly, but which u\) to 

 the present had not received any mention at all, although 

 it had been discovered four ov five years ago. It was a 

 kind of operculum, which had been handed to Professor 

 McCoy, but had never been descr-ibed. It seemed to corres- 

 pond with the Gyclonema a/ustralis, and he thought it 

 would be well if something were done in connection with 

 the specimens he had mentioned. There were several other 

 specimens of the coral type, some of which were very 

 nteresting, and which he had not been able to identify at 

 all. He would be glad to hand them over to any Member 

 who would undertake a description of them. 



Mr. Hall said that Mr. Pritchard had forgotten to 

 mention that one of the specimens of which he had spoken, 

 the operculum of some shell, had been discovered wedged 

 into the mouth of an Euomphalus. Whether it belonged to 

 the Euomphalus or not was a matter which would admit of 

 discussion. They were all obliged to Mr. Cresswell foi- his 

 interesting paper. 



The President said that he had been in the vicinity of 

 the Upper Yarra a good many times, but did not remember 

 noticing any limestone. However, he had not been on a 

 geological ex])edition, and it was perfectly possible there was 

 plent}^ of limestone which he had not noticed. 



Rev. Mr. Cresswell, in reply, .said that if any limestone 

 did exist on the Upper Yai'ra, it was just in position to be a 

 repetition by flexure of the limestone at Lil3^dale. It was a 

 mistake to suppose there were no other beds of Upper 

 Silurian limestone in Victoria. There were two very 

 extensive thick beds in Gippsland, one at Walhalla, near 

 Cooper's Creek, and another at Deep Creek, about seven oj- 

 ten miles from Walhalla. They were nearly parallel seams 

 of limestone, and might be a repetition by flexure. The 

 fossils Avere very similar in both. These beds had been 

 known for a considerable number of years, and were alluded 

 to in the Geological Survey Reports. In conclusion, he
