Silurian and Devoyiian. — That portion of these formations 

 which occurs immediately to the west of this area, has been 

 already described by one of us.| In the immediate neighbour- 

 hood of Orange, numerous outcrops of slates occur, which are 

 well shown in the cuttings along the Forbes-Molong Railway 

 line. No fossils have been found in these slates, but they are 

 probably of Silurian age. A small outcrop of Silurian limestone 

 occurs on the Canoraodine Creek, in the south-western part of the 

 area. All the Palaeozoic strata have been subjected to consider- 

 able folding, and have been subsequently much denuded. As 

 some of the fossils from this district had not been determined 

 and described when the description of the formations in which 

 they occur was printed, and the names of some have been altered, 

 a corrected list is here included.
