DESCRIPTIONS OP SPECIES. 317 



width of only about 1 mm. and a height of one-half mm. The shape is transversely 

 elliptical, there being very little difference in height apparent between the two ends. 

 The median lobe is small, circular, strongh^ marked, and has about three-fifths of the 

 shell anterior to it. A deep furrow bounds it centrallj^, giving off a branch which 

 extends a short distance toward the anterior end and disappears, thus marking off, but 

 imj^erfectly, an anterior lobe considerably larger than the small circular one. The 

 dorsal portion of the cast is flattened, the anterior abruptly elevated and ridge-like. 

 Locality and horizon. — Castle Rock quadrangle (station 2389) ; Millsap limestone.
