from the limestone at Burragood, on the Paterson Ptiver, and in Europe are 
characteristic of the Carhoniferons Limestone. Specimens of this nature, 
although fragmentary, and sometimes difficult of determination, are of 
importance geologically, as indicating the prohahle presence of an otherwise 
unrecorded genus in our Permo-Carhoniferous rocks. 
The Poteriocrinidae is however chiefly represented uith us hy the 
genus Trihrachlocrinus, McCoy. In Queensland a possible Toteriocriniis 
will he descril)cd^ as P. f Smllhi, Eth. flh, in memory of the late Mr. James 
Smith, of the Geological Survey of Queensland. Like so many of the fossils 
from that Colony, the state of preservation does not allow of an exact generic 
determination being made. In addition to this fossil, the impressious of 
large stems have been found in the Gyrapie Series of the Pockhampton 
District’, very similar to some of those from Elat-rock Creek, Ulladulla, 
Shoalhaven District. As in the case of the latter, the Queensland specimens 
are almost indistinguishable from the stems of Toteriocrinus crassiis, ]\Iiller. 
Other fragmentary fossils found during the progress of the Queensland 
Geological Survey, will he described in the work cited below, hut it is not 
necessary to quote them in detail now.
