In a series of 105 specimens, all are sinistral and most are 

 imperf orate. The embryonic whorls are ochraceous or light 

 brown, darkest near the suture below, fading upwards, the 

 tip dilute brown. The later whorls have a light pinkish cin- 

 namon to cartridge buff ground, weakly marked with cinna- 

 mon streaks and spiral lines or narrow bands. The very nar- 

 row sutural border is pale. The lip has a faint fleshy brown 

 or cream tint. The spire is straightly conic and typically 

 rather long. A small proportion of specimens are indistin- 

 guishable in shape and color from the lighter forms of Pupu- 

 kea valida.
