Very rare. The two specimens found in Gathering No. 7, 

 are rather narrower than d'Orbigny's figures and have 

 the first chamber long and narrow, forming a sort of cauda at 

 the base of the test. 



(The two specimens are very distinctive. In their general 

 outline and acuminate base they are much nearer the specimens 

 which we figured from Selsey, (H-A. & E. 1908, etc., S.B. 1909.-
