Abstract.-- A species of the genus Cyrtospirifer, collected from beds in the south-south-west of the Mount Morgan district , is described and named, and the age of the beds is determined as Upper Devonian .
INTRODUCTION AND AC KNOWLEDGMENTS.
The species of Cyrtospinifer described in this paper was collected by Mr. ]. H . Reid, near the boundary of portions 18 and 21, Parish of Calliungal, County of Raglan, Queensland. The specimens used are the first to have been collected and described from this locality, and indicate the age of the beds here, previously regarded as Lower Carboniferous, to be Upper Devonian. A Research Project Grant, held by the author within the University of Queensland, and financed by Commonwealth funds, has made this work possible. Grateful acknowledgment is made of the invaluable advice and guidance received throughout my investigations from Dr. D. Hill, of the Geology Department, University of Queensland. I am indebted to Mr. ]. H. Reid for the opportunity of studying the material which he collected.
