is an anomaly in terrestrial mollusca, and requires confirma- 

 tion." Who said that Pompholyx was a terrestrial moUusk ? It 

 is fluviatile. Prof. Gabb assures me that the animal has two 

 pairs of eyes, as described, but I think with Dr. Gray that 

 black spots have been mistaken for eyes. I object also to the 

 word "fluviatile" being applied to Auriculadae, and would re- 

 mark that if Dr. Gray had seen the shell of the animal he criti- 

 cizes he would never have suspected it to belong to the Auricu- 

 ladse. Except in the matter of eyes, the animal appears to be 

 a true Lymnaean, both by general appearance, habitat and shell.
