The two pecteiis named are not only abundant but they are 

 also exceedingly well preserved, both valves being not infrequently 

 still joined. P. ineringae is restricted to the Gippsland niiocene 

 and, though so plentiful in the Swan Reach section, is in others 

 within the area a rare shell. P. aniiaustralis is common both at 

 Muddy Creek and in the miocene of South Australia, but we 

 have nowhere seen liner examples than some of those collected 

 here. 



One or two of the stronger eocene shells, as Spondylits (^acdero- 

 pflides and Pecfen yah/ensis, though not as fresh looking as the 

 miocene forms, are still in good condition, especially the latter, 

 and they are besides the commonest of those found in the softer 

 matrix, the eocene species generally, including also these two, 

 being usually contained in nodules of limestone ; for the most 

 part the gastropods are represented by casts only, while with 

 bi vales the tests are frequently preserved. 



It may be remarked here that the miocene fossils obtained 

 were all either lying loose on the face or embedded in the 

 calcareous sand, while none were found as casts. We did not 

 observe them in the limestone, though it would not have 

 been unusual if such had been the case, since at Jemmy's 

 Point there is plenty of miocene limestone, both fossiliferous 

 and unfossiliferous ; indeed, some of the limestone bands in the 

 upper part of the Swan Reach section are probably of miocene 

 origin. 



On our first visit to the locality we collected only two or three 

 species of eocene fossils and of these vei^y few individuals, as we 

 merely picked up those easily seen from their having partially 

 or entirely weathered out from the matrix, but on another 

 occasion a special search was made for them, and by breaking 

 up the limestone towards the base of the section we got a 

 tolerable number, a list of which is given below. As they are 

 nearly all casts, comparatively few of them can be definitely 

 determined specifically.
