212 REMARKS ON FOSSILS OF PERMO-CARBONIFEROUS AGE, 



compared with the above massive species, which is the type of the 

 genus. Pachi/domus is exceedingly characteristic of the Permo- 

 CarboniferoLis beds in Eastern Australia. 



Napier Range Localities. 



Mount North Creek. — At this locality, a creek running into the 

 Lennard, a white and red streaky limestone was collected. It 

 contains the indistinct remains of shells ; one appears to be a 

 Brachiopod, perhaps even a Spirifera, otherwise it is not name- 

 able. 



Lennard River Gorge. — A coarse siliceous and micaceous grit, 

 forming " sandstone bars " in the limestone bed, contains a uni- 

 valve very near to Strajmrollus. Three whorls are visible, with- 

 out ornament or other distinsuishins: feature. 



Another block contains very small valves of a Brachiopod' 

 with the general outline of the ventral valve of Rhynchonella 

 pleurodon ; and another shell with much coarser and more obtuse 

 ribs, with a punctate shell structure. The latter may be either 

 Retzia or Spiriferina. 



A third hand-specimen of siliceous grit exhibits six corallites 

 of a medium-sized Bugose coral protruding from its surface, and 

 partly seen in section, grouped together, but there is no evidence 

 to show that they were fasciculately united. The corallites are 

 circular, with about twenty simple septa projecting into the 

 calices for about two-thirds of their width. The septa converge 

 towards the centre and partially unite, leaving a small tabulate 

 median area. The interseptal loculi are sparsely subdivided by 

 dissepiments, becoming rather closer towards the middle of the 

 corallum. 



The general facies of this coral is to some extent that of 

 Diphyphylluni, and to some that of Zaphrentis. In the absence 

 of additional material for extended microscopic examination, it is 

 provisionally referred to the former.
