ERE AT A. 



It is stated at the bottom of page 51 that II. pachystyloides is a 

 southern form. The passage should read thus : H. pachystyloides, 

 is a northern form, and its place in Carpentaria seems to be taken by 

 H. pomum. H. cerata, now called Coxi, occurs about Port Denison. 



The Shell described at page 52 as Helix infurius is Helix informis. 

 It is described by Mousson in the Journal de Conchyliologie, Vol. 

 XVII., p. 59. As it is not found in Dr. Cox's published list, it may 

 be added that it is peculiar to Port Mackay, and is a large species 

 placed at the head of the group H. Fraseri, Gray, and H. Lessoni 

 Pfr. It has a heavy unshapen aspect, with Qh swollen whorls, forming 

 an obtruse cone 1\ inches long. Color, violet-brown, with a pale 

 band visible only when the mouth i3 held against the light.
