Chondrina hegacheilos (C. & J.). Vol. XXV, p. 7. 



Add to synonymy : Torquilla avena Drap. var. a, parva, 6 x 

 2.5 mm. Var. b, media, 9x3 mm. Stabile, Fauna Elvetica : 

 Conch, terr. e fluv. Luganese, 1845, p. 41. In a MS. note in 

 our copy of this paper Stabile wrote that in 1845 he was a 

 novice in science, and that the science itself had made prog- 

 ress since, so that numerous corrections of his early work are 

 required ; among them he lists his T. avena of 1845 as equiva- 

 lent to Pupa (Torquilla) mcgacheilos Jan, var. minor. In his 

 later work on the same fauna (Prospetto sist-statist. Moll, 

 terr. e fluv. Lugano, 1859, pp. 52, 57) he has the following 

 entry: Pupa megacheilos mut. minor: smaller, very close to 

 P. av&nacea (and on pp. 52, 58) mut. media: double the size, 

 brownish corneous or blackish-brown.
