(g) Mollusca. 



By E. H. Matthews. 



The paucity of land and freshwater shells obtained 

 during the recent expedition is evidently attributable to the 

 lateness of the season and the long period of dry and hot 

 weather. 



The two tubes submitted contained but few specimens. 



In tube No. 1 were two immature Helices; the larger 

 shell was a young Thersites ( Glyptorhagada ) silveri, Angas, 

 size 12 mm. broad by 5 "5 mm. high, the characteristic colour,, 

 bands, and markings being very prominent; the other shell 

 was the young of Thersites ( Xantho melon) perinflata, Pfr., 

 size 9 mm. broad and 7'5 mm. high. Both specimens were 

 taken alive, and the habitat given, MacDonnell Ranges. 



In tube No. 2 were eight specimens of a syntonic form of 

 Physa gibbosa; they were considerably below the normal size, 

 being only 11 mm. long by 4'7 wide, the inflation and 

 thickening of the penultimate whorl showing evidence of 

 unfavourable conditions of growth; habitat same as the 

 others.
