To the list of synonyms given in ' British Conchology' add Cerithium rugulosum, Sowerby, G. subcylindricum, Brusina, and 0„ benoitianum, Monterosato. The description and figure of Delle Chiaje are unmistakable. Professor Martens says that the specific name ought to be metaxa. He is right, and I have altered it accordingly. A specimen from the Bay of Naples, which was obligingly given me by the late General de Stefanis, is almost needle-shaped, being much more slender and narrow than usual; it has only three rows of tubercles on each whorl, the middle row being more prominent than the two others. The first or apical whorl is slightly twisted. Another specimen of the typical form is milk-white. 6. CERITHIOPSIS COSTULATA, Moller. Turritellal costulata, Moll. Ind. Moll. Grcenl. p. 10.
