Conus simplicissimus (Hendricks, 2015)

 

 

Description

 

The shell is thick, stout, the diameter more than half the length, smooth except for delicate growth-lines. Spire conic with concave outlines, the whorls nearly flat, the upper ones angular above the suture. Shoulder rounded, the lateral slope below it somewhat convex, showing very faint traces of five spiral series of rather large reddish spots. Above the shoulder there are some oblique reddish flames. No spirals near the base or elsewhere. Aperture is somewhat widened in the lower third (2). 


Length 68, diam. 42,0   mm. 

          63,   "      33,5    " ; whorls 11 (type). 

          41,   "      25,5 "



A cone of very simple form, differing from others of somewhat similar contour by the absence of spiral sculpture. C. recogonitus is much more contracted anteriorly, and has weak spiral striae. The smallest specimen of the three is that which Gabb referred to C. berghausii Mich., an Italian Tertiary species (2).

Dr. Dall has included C. berghausii Gabb in the synonymy of C. proteus, but it differs from that by the swollen shape, and is certainly distinct (2). 

Type No. 2549.
