GASTEEOPODA. 



The remains of Gasteropoda are of rare occurrence amongst 

 the fossils from the Bowen Eiver coalfield, and are confined 

 to the fragmentary remains of one or two indeterminable speci- 

 mens. They are of interest only because of their occurrence 

 in marine bands in Mr Jack's " Fresh- Water Series ; " and it is 

 to be the more regretted on this account that there is such a 

 paucity of remains. 



The fragments in question were found at Eosella Creek, 

 two miles above Havilah Paddock, and at the Havilah-Byer- 

 win Eoad, one mile south of Eosella Creek crossino:.

Ohs. — Two specimens of this species have been collected by 

 Mr Jack, both of them casts, without any trace of shelly 

 matter remaining. The form of the shell and character of the 

 umbilicus in the Bowen Eiver coalfield specimens correspond 

 quite well with Professor Morris's description and figures, 

 but the depth of the body whorl near the mouth is not so 

 great, although the disparity is greater in one of our speci- 

 mens than in the other. However, this need be dwelt on 

 less, since I find Professor Dana has given such a figure * of 

 G. micromphalus, and on examining those in the Strzelecki 

 Collection I see the same aperture is presented by some of 

 the specimens there.
