(Original description of
Solarium fuliginosum in Latin) The shell is orbiculato-conical, in other words it is essentially a low, depressed cone with a rounded base. The shell is smooth, and adorned with soot-brown coloration. The lower
whorls are smooth and somewhat swollen, while the upper whorls are longitudinally folded (plicate). The median area is pale and is painted with broad, oblique brown stripes. It is keeled at the periphery. Above the keel, there is a narrow, flattened area articulated with quadrate brown spots. The base is slightly swollen, pale, and smooth. The
aperture is quadrate. The umbilicus is wide-open and is furnished with straight brown crenations. The snails have a shell 5 to 7 centimeters in diameter. The cone-like shell coils up from a flat base. The spirals are composed of vibrant shades of black, white, and brown. The body and its tentacles are striped as well to match the shell. Its
operculum is made of a horn-like material. ==Distribution==
