This species is so well defined by the remarkable contrast of the 

 color of the peris tome with the white tint of the rest of the shell, 

 that it will be readily recognized. The edge of the aperture is thick- 

 ened and bright coral-red, and this, both within and without, is 

 rather deeply bordered, especially within, with purple-brown. 

 (Smith.) 



The description is from Smith. The identity of coraliolabris Avith 

 chapmani cannot be questioned.

Imperforate, globose-conic, thin but solid, opaque white, the lip 

 intensely black, Surface lusterless, with rude, irregular lines of 

 growth, obsoletely granulated by spiral lines. Aperture very 

 oblique, white within ; upper lip roundly expanded, sinuated, baso- 

 columellar lip flat, broad, adnate for one-third the distance from

A white, lusterless shell with deep black lip. Although this spe- 

 cies is placed in Acavus by Tapparone Canefri and some others, it is 

 a true Papuina, closely allied to H. diomedes, zeno, naso, etc., 

 differing mainly in the rounded instead of angular periphery.
