Obs. — I have already recorded the occurrence of a species after 

 the type of L. rugifera, PhilL, in the Gympie beds of the Rock- 

 hampton District. Mr. De Yis has now communicated two other 

 species from the same strata, but unfortunately both are too 

 insutficientl}'^ preserved to warrant the application of specific 

 names, although they must not be passed over in silence. 



The larger of the two fFig. 6) possesses seven whorls with a 

 total length of two inches, but the apex and body whorl are 

 wanting. Sufficient of the scvilptvire remains to show that each 

 whorl was traversed by a large number of close set, somewhat 

 sigmoidally curved costjv, extending completely from suture to 

 suture. 



The second fossil is the impression (Fig. 7) of a comparatively 

 small shell, similar in character to PI. xl. fig. 6. The impression 

 is nine-sixteenths of an inch long, and consists of thirteen whorls, 

 similarly sculptured to Fig. 6, but with the costfe less sigmoidally 

 curved. 



Both specimens are of a type common in Devonian and Car- 

 boniferous rocks, and may be considered as appertaining to that 

 section of the genus represented by L. Lefevrei, De Kon. The 

 second may also be compared to L. pulcherrimn, McCoy. The 

 larger of the two specimens (PI. xl. fig. 6) is also closely related 

 to a shell I described* some years ago as L. su/culosa, PhilL, from 

 near Lake Bathurst, N.8. AVales, but in the case of the latter the 

 sigmoidal rug?e ax"e much coarser and less numerous. The shell
