shew the spiral band with sufficient distinctness. 

 Fig. 37. 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 slightly 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 3 

 lines ; length of the aperture 2J lines ; width of the same 2 lines. 



Locality and Formation. Paquette Rapids on the Eiver Ottawa. 

 Black Eiver limestone. 



Collector. Sir W. E. Logan. 



EUNEMA ERIGONE. (N. sp.) 



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 1J 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 lines. Surface unknown.
