The occurrence of the two foregoing species in the Horton 

 River beds is a point of much interest, as it tends to indicate a 

 relation between the lattor and the Lion Creek Limestone, at 

 Stanwell, near Rockhampton, Queensland." The two corals now 

 recorded are accompanied by a second Lithostrotion, intermediate 

 in its structure between L. ? columnare, Eth. fil., and L. ? arun- 

 dineum, Eth. fil.^'^ It is a fasciculate form, generally resembling 

 the last named, but with a much larger number of septa, and 

 these invariably united in pairs, each primary with its secondary. 

 The columella is of the type of L? columnare, rather than that of 

 L. ? arundineum. It may be only a local growth of the former, 

 in which case the characters oi LI columnare will require to be 

 enlarged, or, on the other hand, a closer study, when time permits, 

 may prove it to be quite distinct. 



I am indebted to Mr. E. R. "Waite for the micro-photographs 

 from which the figures are reproduced.
