Some days we spent gathering marines on the little pebbly beaches hidden far down under the lofty cliffs that mark this rugged shore line, and we obtained some unusual species washed up from the exceedingly narrow island-shelf; blue water is but a few hundred yards out. Among these are some _Conus cedonulli_ Lam. Beach collecting is, however, an aggravation; and too much of it becomes a misdemeanor in the collector’s ethical code, for it obliges an acceptance of something short of the best. AMNICOLIDÆ FROM ONEIDA LAKE, N. Y. BY HENRY A. PILSBRY. The New York College of Forestry, under the direction of Professor Hugh P. Baker, is carrying on a biological survey of Oneida Lake and has issued an interesting bulletin[4] upon the relations of mollusks to fish, by Frank C. Baker. Some _Amnicolidæ_ obtained during this work, and subsequent to the preparation of the bulletin were submitted to the writer. The collection proves to be of considerable interest, including some species not before noticed. AMNICOLA BAKERIANA, n. sp. The shell is umbilicate, turrited-conic, thin, whitish-corneous, somewhat translucent, with unevenly developed striation, distinct, and close in places, weaker and sparse elsewhere. The summit is decidedly obtuse, as in _A. limosa_, the first whorl being nearly planorboid; subsequent whorls are evenly, strongly convex. The aperture is very shortly ovate, almost round, its length contained almost 2½ times in that of the shell. Peristome thin, in contrast with the preceding whorl for a short distance. Length 4.3, diam. 2.7 mm.; 5 whorls (type). Length 3.75, diam. 2.3, length of aperture 1.35 mm.; 4⅔ whorls. Length 4.1, diam. 2.75, length of aperture 1.65 mm.; 4⅔ whorls. Oneida Lake; off Short Point in 8½ ft., mud bottom. Lower South Bay, in 18 ft., on mud bottom. This species resembles _A. limosa_ in the conspicuously obtuse apex, but differs by the more elevated, turrited spire and the smaller calibre of the whorls, hence smaller aperture. It is also a weaker shell, with more whorls in specimens of the same length. There is also an abundant smaller form, resembling the typical form in texture, apex and shape of the whorls, varying in form, but relatively broader than the type. There are some intermediate examples, but as Mr. Baker considers it desirable to have a designation for this form, it may be called _A. bakeriana_ form _nimia_. The type measures: length 3, diam. 2.5, length of aperture 1.4 mm.; 4 whorls. AMNICOLA CLARKEI, n. sp. The shell is narrowly umbilicate, conic, a little obtuse at the apex, corneous, nearly smooth. The whorls are very convex, separated by a deep suture, the last whorl tubular. The aperture is distinctly oblique, almost circular, the upper end rounded, but a trifle more narrowly so than the base. It projects but little beyond the preceding whorl laterally. The peristome is thin, continuous, scarcely or barely in contact with the preceding whorl above.
