Show 770 ON SHELLS O F T H E G E N E R A STREPTAXIS A N D E N N E A . [June 6, closely resembling that of the former species, whilst the general shape comes nearer to that of the latter, from which the present species is distinguished by having an additional w*horl and more elongate proportions. The oblique flexuous costulation of E. na-gaensis is finer than the sculpture of either of the allied forms. Several specimens of this species were obtained by Col. Godwin- Austen in the Naga Hills. ENNEA MILIUM G.-A. (Plate L. figs. 18, 19.) In the original figure of this small form l the teeth within the peristome were wrongly drawn. I have recently been able, through Col. Godwin-Austen's kindness, to examine the original type, which is the only specimen hitherto obtained. The locality where this shell was found is in a tract of the lower Himalayas, very difficult of access, lying north of Assam. I find that instead of a single tooth in the right margin of the aperture there are two, one opposite the parietal lamella, the other lower and more internal; there is also a low broad basal tooth and an internal columellar lamella. A fresh figure is given herewith. ENNEA CANARICA Bedd. (Plate L. fig. 25.) This species was described by me in 1880 2 but not figured, and as the form is a remarkable one, I make use of the present opportunity to give a figure. This and the next species differ considerably from the other South Indian Enneas, allied to E. pirriei and E. macrodon, forming the group to which E. turri-cula belongs. E. canarica is from South Canara. ENNEA BEDDOMII Blf. (Plate L. figs. 20, 21.) This was described with the last, and, like it, requires figuring. Both species were obtained by Col. Beddome, to w h o m & I am indebted for specimens. E. beddomii is from the Siva°-iri Hills Tinnevelly. ' EXPLANATION OF PLATE L. Figs. 1, 2, 3.
