hough there is considerable difference in thepublished descriptions of P. bovinus and P. novoseelandicus, 1 think that theyare the same species, as nearly every specimen that I have examined com-bines characters of both. Usually they have the general form and colourdescribed as characteristic of P. novoseelandicus, together with the sevenwhorls and the cherry-red mouth of P. bovinus. Although the shell hasseven whorls, the animal has only three and a-half whorls. Daudebardia novoseelandica, Pfeiffer. (?) The animal has no locomo-tive disc, but a specimen long preserved in spirit showed a central longitu-dinal groove on the foot. There is no jaw. Teeth 15-0-15. There areabout 35 transverse rows of teeth, which form an obtuse angle of about100°, salient posteriorly. (PI. IV., fig. m.) The breadth of the radula is•16 inch, and its length about three times as much. Teeth aculeate, witha central process of attachment. The apices of the teeth belonging to the TRANS.N.Z.INSTITUTE,V0LMP11.

III., fig. E.) The specimen from which the figures were taken was collected by Mr.T. Kirk, at Waiuku, in the Lower Waikato district. The animal waswithout its shell, but from the mark on the body it was easy to see that theshell was pauci-spiral, and on the hinder part of the body. As Daudebardiavovoseelandica came originally from the Waikato, I presume that this is thesame species ; but while the shape of the shell is that of Daudebardia, theteeth appear to belong to Testacella. Pakyphanta busbyi. There is no jaw. The radula is about an inch inlength, and -4 inch in breadth at the anterior end, tapering to a pointposteriorly, with about 104 transverse rows of teeth, the rows forming anobtuse angle of about 130°, salient posteriorly (PI.
