Shell of female sub-ovate, greatest height central, equal to about five-sevenths 

 of the length ; ventral margin well and evenly arched ; dorsal margin nearly 

 straight in the middle, in front well arching to the anterior extremity, behind 

 suddenly deflexed to the hinder margin ; hinder margin obliquely truncate, 

 furnished v^ith a spine process at the infero-posteal corner, which is directed 

 backwards, and a second similar spine process at the supero-posteal corner, which 

 is directed downwards (these spines are sometimes obsolete or rudimentary). 

 Anterior extremity, with the rostrate portion nearly erect, the upper margin of 

 the sinus being straight, and directed with a slight obliquity downwards ; the 

 sinus itself is thus widely open, shallow, and widely rounded at its junction 

 with the ventral margin : surface of valves altogether devoid of any pilose 

 covering, but when in good state elegantly reticulated, the reticulations irregularly 

 hexagonal ; in the older shells this reticulation becomes more and more indistinct, 

 and the surface is (from many localities) curiously eroded, the erosions forming 

 circular or irregular pittings. Viewed dorsally the form is elongated ovate, the
