in length and one and one-half in breadth. It is 

 very heavy. There are seven whorls, and the apex 

 is rather blunt. The body whorl has three rows of 

 knobs running parallel with the suture. The one 

 nearest the suture has longer knobs than the other 

 two rows. The other whorls have only one row of 

 knobs and after the two whorls nearest the body 

 whorl they can hardly be seen. All the whorls are of 

 a light grayish white color, but if held in the sun- 

 light, they have a pearly luster, particularly near the 

 apex. There are great numbers of lines running in 

 the same direction as the knobs, which are raised. 

 The lines of growth are scarcely perceptible. The 

 suture is quite broad and considerably raised. The 

 upper part of the pillar is of a rich black color shad- 

 ing into a bright orange, near the base. The lower 

 half projects in toward the aperture. The inside of 

 the aperture is also of a bright orange color in as far 

 as we can see and is very smooth. The edge of the 

 outer lip curves in, and is very thick. The outside 

 is striped with white and brown. Inside of these 

 stripes there is a brown and silver stripe, running 

 lengthwise, while the other lines run crosswise. At 

 the upper end of the aperture, there is a long point 

 projecting upward. This point is about one-third of 

 an inch in length, and is of a black color. Between 

 this point and the shell there is a broad, deep notch
