revolving striae. These striae turn backward somewhat on approach- 

 ing the band. The largest transverse diameter of the shell is 3 mm. 

 Other dimensions unknown. 



Remarks. This shell is very closely related toB. perelegans 

 from the Kinderhook but differs in its minute size, crowded and 

 evenly spaced revolving and transverse lines. Three specimens 

 observed are all about the same size; some however show the lines 

 somewhat more distant than the specimen described.

Euphemus? sp. Weller. Trans. St Louis Acad. Sci., 9, 2, p. 40, pi. 5, 

 fig. 10, 11, 1899. 



Specimen minute, umbilicated. Dorsal part of the shell com- 

 pressed, but it appears to have been semiglobular in form. Region 

 of the band is obscured. Six widely separated 

 revolving lines shown on half the shell. No growth 

 lines perceptible. Shell 3.75 mm across, with a thick- 

 ness of 2.5 mm.

and figured by Weller from the Vermicular sandstone.

 A poor mold of a large specimen of about four whorls that may 

 belong to the genus. It has a height of about 20 mm, and a diam- 

 eter of the body whorl of about 15 mm. 



Conularia sorrocula nov. gpj 



Shell of small size, pyramidal, enlarging at an angle 

 of 20 . Edges of shell round inward, producing an 

 impressed angle; surfaces nearly flat; mesial furrow 

 scarcely impressed; anterior ends of sides arched for- 

 ward in the center, leaving rather deep angles at their 

 union. Transverse striae arched forward on sides, 

 frequently meeting, sometimes interrupted at the 

 mesial furrow ; ten in 5 mm, on the upper part of the 

 shell, more than twice as many near the base, 

 strongly crenulated by the crossing of longitudinal Conularia sor . 

 wrinkles which appear coarser and farther apart near Qyst^ a bas°in! 

 the angles ; crenulations keel-like, 10 to 13 in 2 mm. Coffin L 



Dimensions. Length, 28 mm; width of valve at aperture 10 mm, 

 incomplete at base.
