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

 Mr. Binney as a small variety of Vancouverentis, with stronger radiatitig and spiral lines ; 

 bnt 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: — " I her us {Cant' 

 pi/leea) sportella, in fam. HelicidcB," and " Discus Vancouveretms, in fam. Stenopirifs." 

 In Albers it is divided as " Macrocyclit nellicata," " M. rancoucerensis" and '^ Meli» 

 (Patula) sjaortella"
