Strophia fusca Maynard, 1889
"STROPHIA FUSCA Novo.
Plate VII, 19 & 19A, shell; Fig. 12; A, front, B, left side.
SP. CR. Size, medium. Shell, not very heavy. Striations, present. Teeth, two and long. Whirls, 11. Examined 46 specimens.
Form of shell, a pointed cylinder with the first whirl the largest in diameter, and the next two
are successively smaller; thus the shell tapers to a rather acute point, making an angle of about 50
degrees The striations are not numerous, 17 on the upper whirl, quite prominent, not regular, nor
arranged in lines, and the interspaces are about twice as wide as the prominences. The striations
are rounded and slightly furrowed.
Aperture, small, but measures a trifle more just within than at the entrance. Lower tooth, prominent, .05 high by .25 long, and its position is just a little to the right of the center; the upper is placed well above it but is not as prominent, yet makes a complete turn around the column.
Margin, not produced forward beyond the diameter of the shell, is slightly inclined to the right, is rather thick measuring. 06, and the outer posterior portion is provided with a thin, not prominent edge. The frontal bar is not well developed and is smooth within.
Color of shell externally, brown, paler at the apex, and with the striations white; internally, pale brown which gradually fades into flesh color on the teeth and margin.
Size of type, 1.25 by .45. Largest specimen, 1.35 by 55; smallest, .90 by .42. Greatest diameter, 1.35; smallest, .42. Longest specimen, 1.35; shortest, .90.
There is considerable variation in this singular Strophia in respect to size, as shown, and specimens are inclined to be shorter and more obtuse, in proportion to the size, and more cylindrical. Some show a thicker margin.
Known from all other species, by the brown color with contrasting, wide apart., white striations, and long teeth.
DISTRIBUTION AND HABITS.
The Brown Strophias occur on the west end of Little Cayman, low down in the thick scrub. They are quite solitary in habit, and rather rare, but it is probable that they range through the higher growth of woodland of this section, at least as far east as the mangrove swamp of which I have spoken."
