PHYSA. 143 



C. SlieU consijicuoiisly striate. 



20. PHYSA SPARSESTRIATA, Tnjon. 



Plate 7, fig. 7. 



Shell ovately cylindrical, spire rather pro- 

 duced, apex acute, suture well impressed; 

 surface malleated and covered with distant 

 sharp, raised growth-lines ; texture quite fra- 

 gile ; outer lip not thickened ; columella nar- 

 row and turning somewhat to the right 

 towards the base, very slightly or not at all 

 folded. 



Length 12, diam. 7 mill. 



San Joaquin Valley, California. 



This species somewhat resembles in its striae 

 Ph. U Orhlgnyana, Lea, but does not other- 

 wise accord with that shell. It is much more 

 slender, more fragile, and has a longer spire 

 than Ph. heterofitropha, Say. In form it is 

 somewhat like Ph. vlrginea, Gould ; but that 

 is a smooth, polished species, of a richer color, 

 frequently almost golden in hue. It is a very 

 distinct shell, of very constant character.
