|---|---|---|
| W. M. Ingram 1948 (Cypraea hertleini) | Shell bulbous, sloping steeply in lateral profile from the dorsum toward the anterior and posterior canals; spire obscured; sides of shell calloused; callosity of sides extends over lateral margins of dorsum, leaving an undulating pattern on top of the dorsum; pattern superficially recalls the dorsal pattern of Cypraea spadicca Swainson; a 4 mm. wide shelf is present dorsally over anterior canal, shelf lacking over posterior canal; base convex, upturned at lateral margins, leaving a barely visible ridge at dorsal margin of upturned basal sides, and recalling a similar condition in Cypraea arcnosa Gray; anterior canal extremity straight ventrally, strongly curved to the left dorsally; posterior canal turned toward the left; anterior canal lips of equal length anterior canal 3 mm. broad by 4 mm. wide; terminal ridge of anterior canal sunken; anterior region of outer lip declivous; outer lip teeth' approximately 4 mm. long; outer lip teeth along anterior one-half of lip have interstices of approximately 1 mm.; along posterior one-half interstices are approximately 1.50 mm. wide; anterior columellar teeth over anterior two-fifths of lip exist as nodules, the longest two extending 2 mm. into the aperture on the columella of the shell; three poorly developed non-noduled teeth are present on the central fifth of the columella; posterior two-fifths of the columella without teeth; barely noticeable depression on columella just posterior to the terminal ridges; columella from terminal ridge to approximately mid-point of its length slightly concave; columella from mid-point to posterior extremity convex; columellar surface just behind terminal ridge approximately 10 mm. deep; aperture 5 mm. wide anteriorly just behind terminal ridge, and narrowing posteriorly to 3 mm. just in front of posterior canal. |
