The first record of this species on the Continent appears to have 

 been due, as already noted, to E. Von Martens, who described it in 

 ]864 (108, p. 349) under the name of 2\ antiquum, from deposits 

 on the banks of the Trtisch, near Omsk. In Denmark it has been 

 found in Pleistocene deposits at Forslevgaard (Sjselland) and Copen- 

 hagen (Johansen, 85, pp. 9, 57, 58 & 67). 



The late Dr. Boettger possessed specimens from the Pleistocene 

 (Mosbach Sand) at Messel (near Darmstadt) and Schiersteiu-a.- 

 Rhein (near Wiesbaden) ; while Dr. Wiist has further recorded it 

 (196) from Mosbach (near Wiesbaden) itself, Mauer (near Heidel- 

 berg) and Hohensachsen (near Weiubeim-an-der-Bergstrasse).
