Somewhat like F. subsiriata, but shorter in length, and considerably 

 more arched at its posterior extremity. The longitudinal strioe, 

 though not very conspicuous, correspond in their general characters 

 with those of F. striata and F. substriata. Rather rare.

" Surface marked with ten or eleven longitudinal acute, prominent 

 strife, and several obsolete intervening ones ; lines of growth fine, 

 numerous; aperture circular." — J. Sowerby. The prominent longi- 

 tudinal striae are always more pronounced towards the posterior 

 extremity, and frequently become obsolete or are altogether absent 

 anteriorly. Sowerby's types in the National Collection do not exhibit 

 the fissure on account of their bad state of preservation ; but its 

 presence is manifest in several of the Museum specimens, in which 

 it is seen to be very short and broad. Common.
