Mr. John Mitchell communicated the following Note. — On 

 one of a number of fossil if erous rock-specimens, submitted for 

 determination by Mr. B. Dunstan, F.G.8., Chief Government 

 Geologist of Queensland, there is present a beautiful intaglio- 

 impression of the head of a Trilobite, referable to the genus 

 Brachymetoims McCoy, hitherto unrecorded from Queensland. 

 The specimen, which apparently represents a new species, was 

 collected in the Mt. Morgan district, and will materially help in 

 determining the geological age of the rocks of that area. Pro 

 fessor McCoy described B. Strzeleckii, n.g. et n.sp., from Dun ve- 

 gan, N.S.W., seventy years ago (Ann. Mag. Nat. Hist., xx., 

 p.231, 1847).
