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

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

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

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

 pylcea) sportella, in fam. HelicidtB" and " Disctis Vancouverensis, in fam. Stenopida" 

 In Albers it is divided as u MacrocycUs veUicata" " M. Pancouverensis" and "Helix 

 (Patidd) sportella."
