Shell elongate, inversely narrowly conical, with the lateral out- 

 lines nearly rectilinear, only the slightest convex, and rather sharp- 

 ly angulated above ; the spire is shortish, concave, probably con- 

 sists of about lo? whorls (the apex is brokein off) and is of a pale 

 pink color ; the four remaining whorls are slightly excavated above 

 and ornamented with a few spiral lirations and the arcuate lines of 

 growth and are articulately dotted at the sutures, which is deepish, 

 with red and white ; the last whorl is sculptured with somewhat 

 distant transverse sulcations, of which the uppe r ones are almost 

 obsolete, and those on the lower portion of the whorl are deeper 

 and closer together than those above, it is of a pale pink color en- 

 circled with two broad orange-red bands, the one above and the 

 other below the middle, and between the sulcations it is ornament- 

 ed with lines articulated with red and white ; the aperture is nar- 

 row, linear and slightly widened at the base, and of a rose color 

 within. 



Hab. ?. 



This species is well distinguished by its narrow form in con- 

 junction with the style of coloration. The two orange-red bands 

 around the last whorl ( of which the upper is rather the narrower ) 

 are somewhat interrupted here and there, and the red dots which 

 together with the milk-white ones, which form the articulated trans- 

 verse lines are very small. 



It belongs to that section of the Genus Conus which includes 

 certain species which are characterized by their regular straight 

 conical outlines, and a rather short and generally shghtly concave 

 spire. To this group, of which C. getieralis, C. Malaccanus, 

 C. planorhis, C. centurio, and C. ermineus are very characteristic 

 examples Morch has given the name Rhizoconus. 



The spiral articulated lines are veiy similar to those which oc- 

 cur in the typical form of C. mindanus. The angle of the last 

 whorl is articulately dotted with short orange-red and white lines 

 (about one line in length) which give the angle the aspect of a faint 

 coronation or more correctly undulation. 



I feel much pleasure in associating with this species the name of 

 a young and clever student in this branch of Zoology.
