As in Madeira, the Leiostyla stock is the most abundant 

 group, and has been notably modified to form the subgenera 

 Senilauria (28:88) and Azoripiipa (27:127). L. c. ancono- 

 stoma and C. mierospora are apparently introduced forms.

Canary Islands. 



The occurrence of a large Gastrocopta on Tenerife is re- 

 markable, but its affinities are unknown, and the record has 

 not been confirmed by any later collector. Lauria c. ancono- 

 stoma and Columella mierospora, common to Madeira, the 

 Azores and Canaries, are the only non-endemic species.
