At various times, shells have been obtained at Jemmy's 

 Point, but no particular attention was paid to them until 

 a year or two ago, when Mr. Gregson, Land Officer at 

 Bairnsdale, sent a number of species to Professor Tate for 

 identification. Amongst many well known forms, of frequent 

 occurrence in other portions of our tertiaries in Victoria, 

 South Australia, and Tasmania, there were also several new 

 species. The material forwarded indicated tliat the deposit 

 probably belonged to the upper division of the tertiaiies, 

 but the determination of its exact position in the series 

 required not only a fuller collection, but also a careful 

 examination of the strata. It was, therefore, proposed by 

 Professor Tate, when in Melbourne at the beginning of tlie 

 year, that I should accompany him on a visit to Bairnsdale 

 and Jemmy's Point ; and with the welcome addition to our 

 party of Mes.srs. Sayce and Pritchard, we succeeded in 

 making an enjoyable, as well as a profitable, excursion to 

 these localities. At the request of Professor Tate, I have 

 undertaken to give the I'esults of our researches. 



I may sa}' at the outset, that I do not pretend to discuss 

 the general geology of the neighbourhood, our time liaving 

 been fully taken up in collecting at the fossiliferous sections 

 indicated to us by Mr. Gregson. Some interesting problems 

 coimected with the underlying and overlying sti'ata pre- 

 sented themselves, but our stay was too brief to allow ut 

 their being fully studied, and they may well be left for local 

 geologists to work out.
