shew the spiral band with sufficient distinctness. 

 Fig. 31.— E. Erigone. 



Description. — Spire acutely conical, apical angle about 30° ; -whorls 

 about seven, slightly convex in the lower half and concave in the upper 

 half ; body whorl ventricose below ; aperture oval, a little effuse below ; 

 outer lip thin ; inner lip absent. Surface with fine but distinct lines of 

 growth which in the upper half of the whorl are curved gently backwards 

 and in the lower half shghtly forward. A little below the middle of the 

 whorls there is a very obscure flat spiral band. 



Length of the only specimen collected 9 lines ; width at body whorl 3i 

 lines ; length of the aperture 2i lines ; width of the same 2 hues. 



Locality and Formation. — Paquette Rapids on the River Ottawa.

Fig. 37. 



Description. — Turbinate, obtusely conical ; apical angle about 80° ; 

 whorls four or five, ventricose, with a flat spiral band about the middle ; 

 suture in the cast deep. The body whorl is most ventricose near the base 

 and moderately convex above to the suture. In the upper whorls there 

 is a shallow concavity just above the flat spiral band. The aperture 

 appears to be obtusely oval. Length of specimen li inches ; width at the 

 aperture about 1 inch ; the body whorl occupies about half the whole 

 length ; width of spiral band on last whorl 2 hues. Surface unknown.
