Strophia nuda Maynard, 1889

Original Description


Naked Strophia.

Plate II, 12 & 12B, shell.


            SP. CH. Size, medium. Shell, thin. Teeth, two, short. Striations, absent. Examined three specimens. Whirls, 10 & 11.

            Form of shell, cylindrical, the first four whirls being about equal in diameter; then the shell curves to a blunt point, making an angle of 65 degrees. There are only faintly defined lines of growth which are more prominent on the upper whirl. Sutures, deep, with whirls bulging.

            Aperture, large and open. Lower tooth, placed to right of center, is not prominent, and is .10 long by .03 high; the upper is a mere eleva­tion at the entrance, is larger within, but is short.

            Margin, not produced forward quite as far as the diameter of shell, and is inclined slightly to the right; it is thin. Frontal bar, not large.

            Color of shell externally and internally, dark flesh, yellowish at apex, and fading to nearly white on margin and teeth. Shell, polished.


            Size of types, 1.00 by .39 and .82 by .32; other specimen, .89 by .38.


            Although I have only three of this singular Strophia which I found near Clarence Harbor, Long Island, Bahamas, I have ventured to name it, as I have never seen anything like it. Known at once by the cy­lindrical form, bulging whirls, short teeth, and naked, flesh colored shell.

            Since writing the first part of this monograph I have seen additional collections, and must say, that I am more than ever impressed with the fact that the genus Strophia needs a thorough revision. I am impelled to form this opinion after noting the doubtful manner in which some collections are labelled. Not only are the most obviously different species, from widely different localities, labelled with the same name, but many names are supplemented with a "?", or with a "var.?"!"
