(it is odd that Tryon should place the species and its variety in 

 different genera) and H. coxeni, Cox, as a variety of TI. prunum, 

 Fer* 



To the same source I am indebted for the following notes : — 



Rhytida leichhardti, Cox, is probably a native of Queensland, 

 though its exact locality is unknown. 



Helix bala, Brazier, is a synonym of H. curtisiana, Pfr., but the 

 locality assigned by Pfeiffer is a mistake. 



Helix stephensoniana, Brazier, is equivalent to H. sardilabiata, 

 Cox. 



Helix mulgravensis, Brazier, should be changed to H. mulgravei, 

 Brazier, as the former name is a misnomer, the shell being 

 received from a trader, and not collected on the Torres Straits- 

 Island as described. 



Georissa multilineata, Brazier, is wrongly placed in Hydrocena. 

 The genus is distinguished by possessing a shelly operculum ; 

 that of Hy'drocena is, on the contrary, defined as " corneum r 

 paucispirum." 



Pupina macleayi, Brazier, is the same as P. petterdi, Crosse. The 

 Endeavour River, not Cooktown, is the correct habitat. 



Ditropis beddomei, Brazier, should read D. macleayi, Brazier* 

 See Pro, Linn. Soc. of N.S.W , Vol, II., p. 122. 



Parmacochlea fischeri, E. A. Smith, is a true species, and in no 

 way related to Vitrina australis, Reeve, as hinted by Tryon. 

 In the list of Chevert shells it is mentioned under the name 

 of V. australis, from the Barnard Islands. Mr. Brazier's 

 collection contains representatives from Cardwell, where it was 

 obtained by Mr. Masters. 



The locality for H. macleiyi, Cox, should be corrected to Whitsun- 

 day Island.
