which have reddish dots scattered in them and along their edges. 

 Sometimes a beautiful shade of green replaces the reddish. It is 

 silvery inside, and corrugated by the folds of the outer surface. The 

 columellar plate is flat and exceptionally broad. The cavity of the 

 spire is large. Perforations four or five, circular, tubular.

A beautiful shell, either pchery-reddish or of a darker olive- 

 green hue, having radiating patches of white. The radiating folds 

 of the upper surface are most prominent around the middle of the 

 last whorl. The perforations are erect and tubular. The green 

 variety was called H. latilabris by Philippi. 



Group of H. brazieri. 



H. BRAZIERI Angas. PI. 13, figs. 67, 68. 



Shell small, rounded oval, flattened ; surface smooth except for a 

 strong rounded rib revolving midway between the spire and the row 

 of perforations, and fine, hair-like growth-stride all over ; the perfora- 

 tions are round, erect, tubular, 4 to 6 in number. Color red, va- 

 riegated with olive-green. 



The shell is about the form of H. pulcherrima but flatter, without 

 radiating folds or spiral striie except for indistinct indications on 

 the spire ; a close inspection shows close fine radiating stride all 

 over. The surface between the holes and the columella is strongly 

 convex. One of the specimens before me is flesh-colored, the other 

 blood-red ; both are curiously variegated with a few zigzag green 

 markings above, and outside of the row of holes there are numerous 

 short flames extending toward the columella. Inside it is silvery- 

 pinkish. The columellar plate is not wide ; it is flat. The cavity 

 of the spire is red inside. Length 30, width 22, convexity 8 mill.
