Of the two species confounded under this designation the _C. arenarius_
appeared as a variety in the manuscript. Of the typical form "Spira
lævi," "Pet. Gaz. t. 75. f. 1," and "Rumph. Mus. t. 33. f. Z," were
cited as illustrations; the other synonyms were ascribed to "Var.
α. coronatus spinis obtusis." The colouring was not mentioned.
