Probably only a variety of L. mardincnsis. It is more 

 evenly long elliptical than that species, being slightly rounded 

 on the base instead of arcuate. According to its author it has 

 slight lateral teeth. It seems to stand partly between mardi- 

 nensis and wheatleyi, being less inflated than the former and 

 slightly more so than the latter. 

 Leguminaia wheatleyi (Lea). 



Shell oblong, somewhat rhomboid, subcompressed, subsolid, 

 inequilateral; beaks but little elevated or swollen, sharp and 

 turned forward over a narrow lunule, their sculpture very 

 faint, somewhat doubly-looped ridges ; posterior ridge low and 

 rounded, ending bluntly behind below the median line ; surface 

 with numerous growth lines, often with one or more slight, 

 radial ridges or furrows on the posterior slope ; epidermis pale
