1895.] MYODES LEMMUS. 59 
In the commencement of this century migrations took place, 
as follows: — 
1815—16. Nordland (Helgeland*, Ranen*). 
1826—27. Nordmöre (Stangviken*). 
1833. Fimarken (Alten). (Also Russian Lapland). 
1833—34. Nordmöre and Trondhjem Stift?”; Christiansand Stift 
(including Thelemarken). 
An allied migration has probably taken place here from 
both sides of the Dovre and Langfjeld Mountains, and indi- 
viduals reached the Trondhjem Fjord in the North, and 
Lindesnæs in the South. 
1838—39. Nordre Trondhjem's Amt (Grong*); (Jemteland, and the 
adjacent portions of Sweden down to the Gulf of Bothnia). 
This migration was probably allied to the following one. 
1839. Finmarken (Alten?). (On this occeasion, too, Russian 
Lapland.) 
1849. Lofoten (Hasselö*); Fast Finmarken. 
It is probable that this year's migration extended over the 
whole of the counties (Amter) of. Finmarken and Tromsö, 
and the groups of islands within those districts. 
In the latter half of the present century migrations have 
taken place, as follows: — 
1852—53. Southern Norway (Gudbrandsdal, extended to the coast 
towns on the Skien's Fjord). 
1852—53. Southern Finmarken, and the environs of Tromsø”.
