* 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 publication in this Report it takes rank asa species. Mr. Bland 
considers the two identical; yet in Add. Gen. the form is thus divided :—“ Iberus (Cam- 
pylea) sportella, in fam. Helicide,” and “ Discus Vancowverensis, in fam. Stenopide.” 
In Albers it is divided as “ Macrocyelis vellicata,’ “ UM. Vancowverensis,” and “ Helix 
(Patula) sportelila.” , :
