different, but it agrees ia every respect with Cochlostyla. This 

 opinion was evidently shared also by the author of the species, for 

 he says that it is allied to Biilimus fulgetrum, Broderip^ from the 

 Philippine Islands, which is a true Cochlostyla. Reading Gillies' 

 remarks on B. antlpodarmn (Trans. N. Zeal. Inst. Vol. i. p. 60), 

 it gives one the impression that he mistook young specimens of 

 P. bovinus for Gray's species, and in this he was followed by 

 others. Prof. Hutton kindly allowed me to examine specimens 

 in the Canterbury Museum, labelled B. antipodarum, Crray, and 

 they proved to be young specimens of P. bovinus^ but were in no 

 way related to B. antipodarum. 



I am now of opinion that the shell found by Dieffenbach and 

 described by Gray as Bulimus antipodarum has very likely never 

 been found again in New Zealand, and is in reality Cochlostyla 

 fulgetrum, Broderip, introduced accidentally from the Philippine 

 Islands. This suggestion is supported by the fact that Cochlostyla 

 daphnis, Broderip, another species from the Philippine Islands 

 has been found at Picton (Trans. N. Zeal. Inst. Vol. xxiv. p. 280).
