* In the Check-List of Dec. 9th, sportella does not appear. It is generally treated by 

 Mr. Binney as a small variety of Vancouverensis, with stronger radiating and spiral lines ; 

 but in the MSS. sent for pubUcation in this Report it takes rank as a species. Mr. Bland 

 considers the two identical ; yet in Add. Gen. the form is thus divided : — " Iberus (Cam- 

 fylcea) sportella^ in fam. Helicidm^^ and "Discus Vancouverensis^ in fam. Stenopidts." 

 In Albers it is divided &a " Macrocyolis nellicafa," " M. Vamcouverensis" anA" Helix 

 (Fatula) sportella"
