Bursa spinosa [Status Unaccepted]   (Lamarck,  1843) (Sea Snail)
Organism information awaits expert curation
Class: Gastropoda

Length: 18.15-70.00 mm
Diameter: 14.25-38.45 mm
Max height of the aperture: 9.50-28.10 mm

Color: The shell is uniformly smoky brown.

The shell is somewhat dorsoventrally depressed, and the whorls are slightly angulated. The most characteristic feature of the shell, however, is the presence of strong spines; each whorl has a pair of varices, one on each side of the shell as in Bursa granularis, but in the present species these varices are produced into strong, elongated, outwardly directed spines at rather irregular intervals. There is also a single spine adjacent to the posterior canal; this spine is directed backwards. In addition to the spines on the varices, there are one or two regular, spiral rows of widely spaced, short, pointed, spine like tubercles. The edge of the outer lip presents a frilled appearance owing to the presence of strong, irregular, transverse teeth.
