tianstad, at Ignaberga. (Malm, Gotheborgs Kongl. Veten- 

 skaps och Vitterhets Samhalles Handlingar, 1851, p. 123). 



If. C. LUBRICA NITENS 'Kok.' Gallenstein. 



The shell is large, 7 to 8.5 mm. long, and usually dark 

 colored. 



Central Europe: Carinthia; Danube at Regensburg, in 

 damp situations; Sweden and Finnland. 



Similar large forms occur in Algeria, interior China 

 (C. davidis), and Japan; but these eastern forms are prob- 

 ably independent derivatives from the wide-spread lubrica 

 stock. Several names have been applied to the large Euro- 

 pean form or forms, but with present knowledge all may be 

 referred to C. I. nit ens. The original descriptions follow. 



A. nitens 'Kokeil' Gallenstein. This snail differs from 

 the preceding [A. lubrica, alt. 2.5 to 3, diam. 1 to 1.5 lines] 

 by the considerably larger and darker colored shell. Marsh- 

 land south of Klagenfurt, in grass etc., Carinthia. (Acha- 

 tina nitens Kokeil, v. Gallenstein, Karntens Land- und Siiss- 

 wasser-Conchylien, in Jahrbuch des naturhist. Landesmus. 

 von Karten, 1852, p. 75. Also the same Jahrbuch for 1900, 

 p. 88, as Z. lubrica form major). Reported by Westerlund 

 from Sweden and Finnland. In his later work Gallenstein 

 gives the dimensions as 7 to 8.5 mm. long, 3.5 wide, and 

 states that it occurs in damp places; while the var. minima, 

 4 to 5 x 1.8 mm., (with which he unites lubricella and exigua) 

 inhabits dry places and high altitudes. 



The name nitens was originally a collection name. It was 

 never described by Kokeil. It was no doubt this form which 

 Parreyss, in his Verzeichniss of 1849, listed as " var. nitidus 

 Kokeil"; but without description. Gallenstein was the first 

 to supply a definition of the race.
