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

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

 but in the MSS. sent for publication 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 (Cattf 

 pi/I(ea) sportella, in fara. HelicidcB," and " Di^scus Vancouverensis, in fam. Slenopidce." 

 In Albers it is divided as "Macrocydis vellicata" '' M. Fancouverensis" and " Helix 

 iPatvla) sportella"
