124 HALIOTIS. 



Group of H. pulcherrima. 



H. pulcherrima Marty n. PL 13, fig. 69. 



Shell small rounded-oval, flattened ; distance of apex from margin 

 about one-fourth the length of shell ; surface finely corrugated by 

 radiating deep folds. Perforations generally 8, small, round, tubular ; 

 the row bordered on each side by a shallow channel. 



This little shell is straighter on the right than on the left margin. 

 The color is whitish or flesh-colored with broad oblique red rays. 

 The surface is finely corrugated, the folds strong, close and numer- 

 ous, not extending quite to the row of holes ; their summits are 

 crenulated by inconspicuous spiral strias. Outside of the row of 

 holes the surface slopes flatly to the strong angle or carina at the 

 columellar margin ; and the descending folds on this portion are 

 cut into granules by spiral stride. The spire is somewhat elevated. 

 Inside it is silvery. The columellar shelf is flat, rather wide. 



Length 27, width 21, convexity 7 mill. 



Length 26, width 20, convexity 9 mill,

A beautiful little shell, with finely corrugated surface. 



Group of H. ovina. 



H. ovina Chemnitz. PI. 19, figs. 7, 8. 



Shell rounded-oval, depressed, distance of apex from margin a 

 little less than one-fourth the length of shell ; perforations tubular, 

 elevated ; upper surface with strong radiating folds ; green or red- 

 dish, radiately painted with white ; inside silvery ; columellar plate 

 flat, very wide. 



The shell is rounded-oval, quite flat ; the whorls of the spire hav- 

 ing a corona of tubercles ; the last whorl has radiating folds some- 

 times ending in a series of knobs around the middle of the upper 

 surface ; some trace of fine spiral cords may usually be seen near 

 the lip. The elevated tubular perforations are situated upon a low 

 keel ; below this there is a depression and then another keel at the 

 periphery, upon which there are several granose spiral cords. The 

 color is ochraceous-pink with broad radiating patches of white,
