PUPILLA, EUROPE. 181 



Descriptions of forms considered synonyms of muscorum 

 follow. 



Pupilla saliniensis 'Bgt.' Locard. Subcylindric, a little 

 elongate ; 7 quite convex whorls, suture quite deep ; umbilicus 

 moderate ; aperture relatively small, quite round ; peristome 

 interrupted, a. little thick, quite reflected, with a strong, 

 white, external crest; one dentiform superior fold, exactly 

 median, a little immersed ; shell a little thin, corneous light 

 red, a little transparent, ornamented with fine stria?. Alt. 

 '!'-, diam. li/4 mm. Rare. Salins (Jura). (Locard, Ann. 

 d'Agricult. Lyon, (7), iii, 1896, p. 217; Conchyl. Fr., 1894, 

 329.) 



Var. transsilvanica Kimakowicz. The Transylvanian form 

 is distinguished from that of Western Europe by the quite flat 

 whorls, separated by very shallow suture, and further by the 

 almost invariable lack of the denticle on the parietal wall 

 (the palatal denticle is never present), and by the relatively 

 weakly developed peristomial callus. The size varies from, 

 alt. 2.5, diam. 1.5 mm., 6 whorls, to 3.7 : 1.7, 7 whorls (Pupilla 

 muscorum var. transsilvanica Kim., Verh. u. Mittheil. Sieben- 

 biirg. Ver. naturwiss. in Hermaimstadt, xl, 1890, p. 106). 



Var. gabrielensis De Gregorio. PI. 20, figs. 14, 15. A little, 

 very elegant, cylindric species, mammillate, having a strongly 

 developed tooth on the coluniellar lip, properly speaking; it is 

 mainly from this character that I have proposed this variety. 

 Sargente del Gabriele near Palermo ; beech woods of Madonie 

 and S. Giro near Palermo (Pupa muscorum L. Mull. var. 

 gabrielensis De Gregorio, II Nat. Sicil., xiv, Sept. 1895, p. 205 ; 

 referring to Benoit 's figures of Pupa muscorum, 111. sist. crit. 

 icon. test, estramar. Sicilia, pi. 5, f. 41). Benoit 's figures are 

 copied and De Gregorio 's description translated. It is prob- 

 ably of no racial value, merely a Sicilian " unidentata" or 

 rnut. marginata. 



8. PUPILLA AUCAPITAINIANA (Bgt.). PL 20, figs. 18, 19. 



Shell minute, deeply and very narrowly umbilicate, globu- 

 ose or ventricosely suboblong, thin, fragile, glossy, pellucid, 

 smooth, pale corneous or slightly greenish corneous. Spire 

 obese, at the apex obtuse. Whorls 5!/2 to 6, convex, regularly, 

 slowly increasing, separated by an impressed suture ; the last 

 whorl a little larger, rounded at base, straightened at the in-
