GASTROCOPTA OP THE MASCARENE ISLANDS. Vol. XXIV, p, 

 127. 



M. Germain has proposed a new genus, Falsopupa, for the 

 species exigua H. Ad., microscopica Nev., lienardi (=> lieii- 

 ardiana) Crosse and desmazuresi Crosse (Bull. Mus. Nat. 

 d'Hist. Nat. Paris for 1918, no. 7, p. 521; this number re- 

 ceived at the Academy Oct. 14, 1919). 



This list contains species of two genera. No diagnosis of 

 the group was given, and no species was selected as type. I 

 take Pupa lienardiana Crosse (Falsopupa lienardi Crosse of 

 Germain's list) to be the genotype. If the views of the 

 affinities of the Mascarene species expressed in Vol. XXIV, 

 pp. 127-133, are upheld, Falsopupa will become a synonym 

 of the typical section of Gastrocopta.
