Mollusks. 60 HELICIDiE. palatal plates also are seen to be much broader than in the other species, and the three upper ones are much more oblique, re- sembling in this respect the immature plates found by me in three of the other species.

The late Col. Beddome lent me several adult examples of this species for examination, one of which is of interest from the fact that it exhibits, in addition to the mature armature, immature plates which are identical in form and position with those I found in an adult shell of CoriUa odontopliora. With these adult examples was an immature shell with three whorls Fig. 16.—Corilla anax. which is specially noteworthy in that it possesses two sets of immature plates, one near the end of the third whorl, and the other a little beyond the place where 2 J,- whorls haye been completed. It may therefore safely be inferred that the plates are not absorbed till after completion of the new ones, and it will be remembered that this is not an isolated case, for two sets of plates have been observed by me in a full-grown specimen of Gorilla odontopliora, and Col. Beddome lent me a shell of this last-named species, identical in this respect. He informed me that he collected his specimens of Corilla anaie in the Anamullay Hills, in the Coimbatore District of South India, in moist woods, at 2000 feet elevation, where it was very abundant on and under dead logs. The specimen shown in fig. 16 is in Mr. Ponsonby's collection. 70. Corilla gudei, Syhes. Corilla gudei, Sylies, Proc. jNIalac. Soc. London, ii, 1897, p. 234, pi. 16, figs, 8-10; Godwin-Austen, Moll.
