SMITH ON THE GENUS CHILINA. 845 are of a brownish colour, and not strongly marked, and more like those represented in the figure of Q. acuminata, which is undoubtedly the same species. 13.

Chilina globosa, Frauenfeld, Verhandl. zool.-botan. Gesellsch. Wien, 1866, p. 197 (woodcut). Hab. La Plata {Frauenfeld). This is a very globular form, bearing relationship to C. fluminea. 15. CHILINA PATAGONICA, Sowerby. Chilina patagonica, Sowerby, Conch. Icon, f. 11 (bad). The outline of the above figure is fairly correct; but the colouring in the copy of the monograph before me is altogether misleading. The epidermis is olivaceous yellow, marked at intervals with a longitudinal brown narrow stripe, indicative of periods of growth. The transverse spotting is in four principal bands; and a fifth, less conspicuous, is noticeable immediately beneath the suture. The next beneath is the broadest band. The aperture is not yellow, as represented by Sowerby, but whitish, bluish white, or sometimes tinged with brown. The fold, too, on the columella is not nearly so prominent as it appears in the illustration referred to. 16. CHILINA SUBCYLINDRICA, Sowerby. Chilina subcylindrica, Sowerby, Conch. Icon. f. 16. HaB. Ancud, on the north of the island of Chiloe, South Chile {Dr. B. 0. Cunningham). The specimen forming the type of this species, together with others, were collected hy Dr. Cunningham during the Surveying Expedition of H.M.S. ' Nassau ' in 1868. The figure is incorrect, both as regards outline and colour. The penultimate whorl appears decidedly too high, making the spire too elongate. The colour is stated to be " purplish brown," which is altogether imaginary. The specimens which Mr. Sowerby had before him were coated with a blackish earthy deposit. On removing a portion of this, the ordinary greenish-olive epidermis is discovered beneath, while the shell is ornamented with four transverse bands of brown more or less arrowhead- like spots and lines. The aperture is of a somewhat pale |
