The adult shell is elegantly spindle-shaped, falling in a little toward the keel which is more or less regularly minutely dotted with reddish brown at rather long intervals. The suture is very distinct, almost channelled. The spire is without revolving sculpture, the sinus deeply concavely arched. There are about seven strong grooves in the adult anteriorly. The very young is deeply grooved all over, as in C. verrucosus. In the adolescent shell the epidermis is thin, and nearly smooth ; it is a little rougher but still thin in the adult. The former has a somewhat waxen translucency, the adult is porcellanous. The young is waxen white with faint pink cloudy suffusion and yellowish ill-defined brown patches. These colors are faint at all ages and form no definite pattern, except the dots on the keel. In the young, by transmitted light, it can be seen that there are articulated lines of opaque and more translucent character, but these have hardly any color and are lost in the adult state. The interior of the aperture is white or nearly so, the mouth is rather wide, the apex of the spire neatly pointed. The adult has about ten whorls, with a total length of 45.0 mm, and a maximum width of 23.0 mm. The spire rises 10.0 mm behind the aperture.
DESCRIBED AS Conus agassizii

As Conus agassizii:
Shell spindle-shaped, the outline of the last whorl swollen a little at the middle; entire surface of this whorl except the extreme upper part grooved, the grooves stronger below; lower ridges shouldered; spire high, straight or a little concave; suture distinct, almost channeled; whorls on the spire channeled and sculptured with elegant curved riblets; shoulder sharp and dotted with reddish brown. There are faint revolving series of brown dots on the body whorl, and a few irregular longitudinal brown flames on the spire and body. Length of specimen obtained, 27mm. ; diameter, 14 mm.
Mayaguez, Porto Rico, one fine young shell.

Conus mindanus Hwass, 1792 Bermuda Cone
Distribution: Texas, Florida; Aruba; Brazil. Size: 50 mm (2 in).
Description: Color variable, typically whitish with faint splotches and bands of yellowish to pinkish; shape biconic; sculpture of spirally arranged punctae that run parallel to faint spiral grooves that become spiral threads anteriorly; axial sculpture of numerous, somewhat long axial growth lines; spire straight sided; aperture oblique with sides almost parallel to one another; base with numerous conspicuous spiral grooves. Habitat: Usually in sediment at depths from 0 to 210 m (700 ft). Remarks: Specimen in photograph collected by J. Nill at Stetson Bank; archived at Brazosport Museum.
