Introduction. — At a meeting of this Society, held in April, 1888, 

 the Hon. W. Macleay exhibited some fossils from the neighbour- 

 hood of Derby, North-western Australia. They are contained in 

 a sandy ferruginous rock, and are said by Mr. Froggatt, who 

 collected the specimens, to come from a small area mapped by the 

 late Mr. E. T. Hardman,"^ as a portion of his Pindan Sands. The 

 position indicated by the collector on the chart in question coincides 

 with a portion of Hardman's Pindan Group. The latter regarded 

 these deposits as of Tertiary age, and distinctly states that they 

 proved to him unfossiliferous. 



Great, therefore, was my surprise to find the organic remains 

 exhibited clearly of a Carboniferous facies. Mr. Macleay was 

 kind enough to allow me to have the loan of the specimens in 

 question, with others from neighbouring localities, in the latter 

 case unquestionably from the great Carboniferous area of the 

 Napier Range, as mapped by Mr. Hardman, and obtained by Mr. 

 Froggatt during the same visit. The full list of localities is as 

 follows : —
