Its color is light brown ;its length is sometimes more than an inch, and itsbreadth is the same. In Fig. 69 we have the representation of a morecommon Turban, or Chlorostoma, which name meansGreen-mouth, and refers doubtless to the greenishnacre within the aperture. This species is named Chlorosto-ma brunneum, Phil., brun-ne-um,and we will call it the Brown Tur-ban. When found alive, as it maybe, on the rocks at very low tide, oron the kelp if you have a boat,this mollusk has a handsome, richbrown shell, with a portion of white around theaperture. The base is flattened, the umbilicus isclosed, and the lines of growth are very oblique;while the edge of the outer lip is very sharp. Even the dead and worn shells preserve their brown. Fig. 69. 84.

Old and over-grown specimens, an inch and a half long, aresometimes found, but one-half that length is morecommon. Chlorostoma aureotinctiim, Fbs., au-re-o-tink-tum,Gilded Turban. The shell of this species is similar in shape to , but the whorls, instead of being nearly smooth,are banded by a few very heavy, rounded spiralridges, and wavy crossings. The shell is gray ornearly black; the umbilicus is large and marked witha bright yellow stain, which gives the species itsname. The shell is about an inch long. The Speckled Turban, Chlorostomagallina, Fbs., gal-li-na, is shown inFig. 70. ^ / It is about the size of the last spe-cies, and has a solid shell, mostly blackin color, but finely mottled with alighter shade, like the feath
