They are here much finer than to the southward nearer 

 the source of the material of which they are composed. 

 Overlying these sandstones is the basal bed of the Windsor 

 series proper, a massive grey limestone lo feet (3 m.) 

 thick which forms a prominent point projecting into the 

 bay. 



In the following paragraphs, the beds of the basal 

 member (c) of the Windsor series are numbered in ascend- 

 ing order, as they occur along the shore northwards. 



1 . Massive grey oolitic limestone, which 

 forms a prominent point projecting 

 into the bay. Occasional fossils, 

 chiefly Producti, occur. This is bed 



51 of Robb's section at Sydney 10 ft. 



(3 m.) 



2. Red clay shales with thin limestones, 

 very poorly shown along the shore 

 just north of the last point; about. . . .40 ft. 



(i2-2 m.) 

 (Beds 3 to 8 inclusive are exposed on the shore just south 

 of the old wharf.) 



3. Coarse sandstone and conglomerate 

 with red shale 4 ft. 



(i -2 m.) 



4. Grey nodular limestone, greenish and 



black shale 8 ft. 10 in. 



(2-7 m.) 



5 . Thin, soft, coarse sandstone with plant 



remains 2 ft. 6 in. 



(i-4m.) 



6. Bluish grey nodular limestone; fossils 

 abundant and surrounded by con- 

 centric deposits of limestone which 

 are apparently original. One of the 



best fossils beds of the section 2 ft. 4 in. 



(0-7 m.) 



7 . Sandy shales with abundant concentric 

 nodules containing Producti 2 ft. 2 in. 



(0.6 m.) 



8 . Light grey, thinly bedded limestone 



with Producti 9 ft. 



(2-7 m.)
