The hamlet of Anglesea lies near the mouth of the so-called 

 " river " of the same name, eight miles in a direct line south- 

 west of the mouth of Spring Creek, the typical locality of the 

 Jan Jukian beds of the tertiary series. The old name of the 

 Anglesea River was Swampy or Salt Creek. Six miles further 

 to the south-west. Airey's Creek enters the sea at Airey's 

 Inlet, and from here eight miles away across Loutit Bay, the 

 houses of Lome may be seen nestling on the wooded flanks of 

 the Otway Hills. 



Previous references to the geology of the district are scanty. 

 Daintree in 1863, after briefly discussing the section displayed 

 at Bird Rock, mentions, half-way between Point Addis and Jan 

 Juc, the presence of cliffs of sands, black with carbonaceous 

 matter. In them, he says, " a remarkable instance of the pre- 

 servation of fossils occurs. All the large imbedded shells are 

 entirely decomposed, and where their casts remain they are 

 imperfectly rendered in iron pyrites, whilst minute foramini- 

 ferae, abundant in the rocks, are preserved intact."' He does 

 not say whereabouts in his series he would place these beds. 



Krause, in 1871, after a very hurried survey, roughly mapped 

 the Cape Otway District, and several notes are given on the 

 coast between Spring Creek and Point Castries, where the ter- 

 tiaries thin out on the Jurassic strata. A few corrections in 

 detail are required. Thus the dips given are usually the 

 apparent, and not the true ones. A creek is shown entering the 

 sea on the east side of Point Addis, and another about a mile 

 east of Salt Creek (Anglesea River), though neither of these
