FRESHWATER SHELLS OF AUSTRALIA. 2G1 



Lip broadly siuuated at the upper part aud promineut below. 

 Columella covered with a whitish callus. Length 31 millim., diam. 

 9, aperture 9 long and 4| broad. 



10. Melania queens lakdic a, n. sp. (Plate V. fig. 11.) 

 Shell ovately subf'usiform, thick, decollated, greenish olive, 



smooth ; sculptured with lines of growth, and a few revolving 

 striae at the base of the body-whorl. Volutions ? 10 ; four or 

 five remaining ones flat at the sides, divided by a deepish aud 

 slightly oblique suture. Spire apparently rather sharply conical. 

 Last whorl long, flattish at the upper part, very little rounded at 

 the middle and below. Aperture bluish, elongately subjjyriform, 

 oceupyiug about three eighths of the probable length of the shell. 

 Lip thin ; view^ed laterally, it appears broadly siuuated at the 

 upper part, and very much produced at and below the middle. 

 Columella thickened with a white callus below the middle where 

 it joins tbe base, only a little arcuate. Parietal callosity thin, 

 bluish. 



Probable total length 40 millim., actual leugth of four whorls 

 33, diam. 12, aperture 14^ long and 6 wide. 



Hob. Saltwater Creek, Cardwell, Queensland, near the coast ; 

 and Paroo Eiver, Queensland (^Brazier). 



This is very distinct from any other of the Australian species. 

 The smooth surface, the gi'eenish-olive colour, the decollated spire, 

 and especially the long body- whorl are the principal charac- 

 teristics. 



11. Melania Elseyi, u. sp. (Plate V. fig. 12.) 



Shell elongate, acuminate, olivaceous (probably), spotted and 

 streaked with reddish brown. Whorls 10, somewhat convex, fur- 

 nished with slightly oblique and arcuate plicae (about 12 on the 

 penultimate whorl), crossed by a few spiral striae, which are most 

 conspicuous near tbe suture, both above and below. Plicae upon 

 the last volution obsolete about the middle, the transverse striae 

 extending to the base. Aperture ovate, acute above. Columella 

 coated with a callosity. 



Length 31 millim., width 10|^. 



Sah. Australia {J. R. Elsey). 



This species is more elongated than M. amtmlis, with finer 

 spiral striatiou and difi"erently coloured. Unfortunately the only 

 specimens in the Museum are in a dead condition and have lost 

 the epidermis. This probably was of an olivaceous tine. The
