Shell medium sized for the genus, 51-69 mm in length at maturity, frondose. Spire modera¬tely high with 2.25 protoconch whorls and up to 6 weakly shouldered, broad teleoconch whorls. Protoconch whorls rounded, sculptured with strong axial ribs, more apparent on last whorl; terminal varix strong, thick, almost straight. Suture impressed. First and second teleoconch whorls with 10 axial ribs, third whorl with axial ribs and forming varices, fourth, fifth and sixth teleoconch whorls with 4 varices. Each varix of last whorl with 5 medium sized spines, adapical (shoulder) spine longest, other spines decreasing in length abapically. Short intermediate spine between shoulder spine and second abapical spine. Spiral sculpture throughout consisting of numerous cords of varying strength. Aperture rounded. Columellar lip smooth, weakly erect abapically, adherent adapically. Anal notch shallow, broad. Outer lip erect, crenulate; strong, large, narrow labral tooth abapically. Siphonal canal of moderate length, narrow, straight, abaperturally bent at tip, narrowly open, with 3 short open spines. Light brown with darker spiral cords, and brown peripheral band at adapical part of whorls. Aperture whitish with pink rim.

Chicoreus bundharmai is close to C. ramosus (Linne, 1758) from which it differs primarly in its longer, more prominent labral tooth, in having 4 varices instead of 3 on the last teleoconch whorl, and in having a strongly axially sculptured, instead of smooth, protoconch. Chicoreus bundharmai is also similar to C. cornucervi (Roding, 1798) but differs in having 4 varices on the last teleoconch whorl, in attaining smaller size with the same number of teleoconch whorls (average size of C. cornucervi is of 90 mm in length), while the varicial spines are generally shorter. The protoconch in C. cornucervi is twice as large and strongly keeled.
