lamellifera, T. Woods ; Corhula pixidata, Tate ; Plnciinanomia, 

 sp. ; Fectuncidus, sp. ; Magellania garibaldiana, Davidson. Also 

 polyzoal remains and cidaroid spines are fairly abundant, and 

 what appears to be remains of woody fragments. An inspection 

 of the above list will suffice to show that the lower portion of this 

 deposit at any rate may be referred to Eocene. Lithologically 

 there does not seem any marked indication of difference in 

 character in the outcrop at the top of the railway cutting, but a 

 few obscure impressions in the higher portion render it necessary 

 that very careful collecting should yet be done at this spot, in 

 order to prove more conclusively than the present material will 

 permit the existence or absence of the upper or Miocene beds. 

 One incomplete specimen appears to indicate the presence of 

 Leda crassa, Hinds, and another, Mactra Jiamiltonenais, Tate, but 

 before making absolute identifications I should like more material. 

 This adds another important link in the chain of fossiliferous 

 localities previously recorded. 



ON A NEW ZEOLITE (MOORABQOLITE). 

 By G. B. Pritchard, 

 Lecturer on Mineralogy, &c., Working Men's College, Melbourne. 

 {Read before the Field Naturalists' CI uh of Victoria, 10«/j June, 190L) 

 During the course of several visits to the Moorabool Valley, in 

 the neighbourhood of Maude, for geological investigations, a fairly 

 common mineral has usually been obtained, which upon critical 

 examination proves to be worthy of being regarded as a new 

 variety, and which I propose to call Mooraboolite. 



'J'his mineral is evidently derived from the decomposed older 

 basalt, for numerous specimens can be readily procured on the 

 basaltic and sub-basaltic slopes. At first sight one might easily 

 mistake this mineral for Arragonite on account of its occurrence, 

 appearance, and usual radial rosette form. In fact, it seems pretty 

 certain that this mislake has already been made by the members 

 of the Geological Survey and by Mr. T. S. Hall and myself. In 

 the first place it may be noted that on Geological Quarter-sheet 

 19, S.W., surveyed by Messrs. C. S. Wilkinson and R. A. F. 

 Murray in 1865, a note is printed over the area where the present 

 mineral was found — " Older basalt, containing Arragonite." Mr. 

 Hall and I, on finding the mineral, incautiously accepted the 

 note on the geological map, and until a short time ago made no 

 independent tests to confirm it, so that in a paper written by us on 

 the Older Tertiaries of Maude, and read before the Royal Society 

 in 1894, the following remarks were made : — "The older volcanic 

 rock in the district is much decomposed, and towards its upper 

 part is full of amygdules of carbonate of lime, while some lumps
