This species, though evidently a Latirus, shows no 



signs of the columellar folds supposed to be characteristic 



of that genus. In this respect, however, it does not stand 



alone, the same being observed with regard to L. gibbulus 



Gmel, and the species from the Cape de Verde Islands, to 



which I recently gave the name of Z. maxinius ('The Con- 



chologist,' 1893, vol. ii., p. 139, pl. i, fig. 5).
