THE GEOLOGY OF FLINDERS. 

 By G. B. Pritchard. 



(Bead before the Field Naturalists^ Club of Victoria, 19th January, 1901.) 

 My intention in submitting a few geological notes on this district 

 to members was not to write a detailed paper, but rather to 

 explain some of the more interesting natural features along this 

 part of our coastal line by means of lantern views, in this way 

 reviving old memories of many present who have had the oppor- 

 tunity of enjoying the wondrous workings of nature in this 

 neighbourhood, and to others, perhaps, a new interest in coast 

 scenery for future enjoyment. This locality has been known 

 geologically for a very considerable time, having been mapped 

 and reported on in the first place by Mr. A. R. C. Selwyn as 

 early as 1854; but, strange to say, though so interesting, very 

 little work has been done since. One of the points of attraction 

 has been a small outcrop of Older Tertiary limestone and sand 

 on the shore-line just below the racecourse, and about a mile 

 west of West Head. This spot has been honoured by a very 

 large number of visits from geologists, but still it appears as rich 

 as ever in organic remains. At first sight there does not appear 

 to be much variety, but one is struck by the abundance of 

 Foraminifera, Calcisponges, and Polyzoa, but on closer investi- 

 gation the fauna shows very interesting variety, for, in addition to 

 the groups already mentioned, representatives of Echinoderma, 

 Palliobranchiata, Crustacea, Cirripedia, Lamellibranchiata, and 

 Gastropoda also occur. Some of these remains are in a good 

 state of preservation, being of a type capable of retaining their 

 form, even in such an extremely porous stratum ; but others, 

 notably the Gastropoda, are usually only preserved as internal 

 casts. The character of the enclosing rock being against the 

 retention of the external features, it is seldom that trustworthy 

 identifications can be made. One group of fossils to which con- 

 siderable interest attaches is that which has been so ably worked 

 at by Dr. G. J. Hinde— namely, the calcareous sponges — which 

 proved of considerable value from a biological as well as from a 

 palgeontological point of view. 



Another attraction has been the beautiful zeolites and other
