closely resemble the specimen Meek has identifid as /. proximus, 

 although the beaks are not quite so far forward as in Meek's 

 illustration, but the shells are toO' ventricose for that species. 

 The specimens seem to agree most closely with /. confertim- 

 annuloitus Roem., described from the Eagle Ford shales of Texas, 

 and have therefore been so identified, ; they resemble both of 

 these species, however, much more closely than they do /. hara- 

 bini. The species is apparently somewhat rare as it has been 

 met with only rarely in the recent collections. 



Formation and locality. — Navesink marl, near Holmdel 

 (128^), near Freehold (133), Crosswicks Creek (147^, 19S), 

 Mullica Hill (1692). 



Geographic distribution. — New Jersey, Texas.

Description. — "Shell somewhat below the medium size for the 

 genus; subovate in outline, the axis of the shell being directed 

 forward of a right angle to the hinge-line, instead of backward 

 as is usual with nearly all shells. Hinge-line shorter than the 

 width of the body of the shell and forming an angle of about 

 no"" to the axis of the valve. Left valve, the only one known, 

 extremely ventricose, with a rather small beak, which is but little 

 elevated above the line of the hinge, and situated in advance of 

 the anterior margin of the valve. Height of the valve a little 

 greater than its extreme width or length. Surface of the cast 

 marked by numerous, regularly increasing concentric undula- 

 tions, which are moderately sharp on the, crests and the inter- 

 spaces broadly concave. There are also indications of radiating 

 lines along the middle of the valve, as in many species of the 

 genus." (Whitfield.) 



The dimensions of the type specimen are : length, 42 mm. ; 

 height, 45 mm.
