Cominella maculosa, Martyn (1784).
Buccinum testudineum, Chemnitz, Conch. Cat., vol. x, 1788, p. 187, pl. clii, fig. 1454. Buccinum maculosum, Martyn, Univ. Conch., vol. i, 1784, fig. 8.
The name of Chemnitz having to be abandoned as being polynomial, I consulted Mr. Hedley, who is always ready to assist us New Zealand conchologists, as to the name to be adopted. He very kindly sent me tracings of B. testudineum and B. maculosum, suggesting that both represented one and the same species, and that in consequence Martyn's name could be used. The figures, though representing shells of different size, show the same main characters, and the diagnoses do not point to two different species. I compared specimens from seven localities in New Zealand, and I must confirm Mr. Hedley's view as correct.

Following Captain Hutton's latest publication on the genus, the more ponderous shells with a cinereous columella, as they occur from Cook Strait down to Banks Peninsula, were taken as C.maculosa, Mart., but the difference from the Auckland shells, taken for C. testudinea, is so slight that they cannot be kept apart as two species. Moreover, the dentition is the same in the two, as will be seen on examining the figures given by Captain Hutton in Trans. N.Z. Inst., vol. xv, pl. xviii, figs. M, N. In fig. M the lateral teeth are turned over, the outer denticles laying over the rhachidian tooth.
