Ohserralion.s.— In, the absence of the distinctive feature of the 
branching iPachis of the frond, the above determination may be 
regarded as somewhat provisional : but the rhombic form of the 
pinnules and thickened rachis j)oints, however, in. the direction of the 
above species. The form of the i)innules and the odontopteroid 
venatioJi compare very closely with specijnen.s from the Trias of 
Leigh's Preek Coalfield, South Australia. 
The figui'cd specimen was collected by the late Dr. T. S. Hall, and 
is now in the Xational Museum.
