Fissure rather longer than in E. striata ; longitudinal ribbings not 

 so prominent, but otherwise very similar ; shell generally less slender, 

 and not so symmetrical in contour ; anterior portion much swollen. 

 The last-mentioned character is very noticeable in specimens from 

 Bramshaw. E. suhstriata approximates rather closely to E. Brongniarti, 

 Desh., of the Paris basin. J. de C. Sowerby's type of B. acuticostum, 

 var., is in the Natural History Museum. Common.
