If we sum up the uumber of these species we get: — 



Northern types, with a southern Hmit 



at 69 — 70° or further north 



Widely distributed Arctic types with 

 a southern Hmit somewhere north of 



62° 30' . 



Widely distributed Arctic types, distri- 

 buted from Cape Farewell to the north 



of Melville Bay 



Widely distributed species with, how- 

 ever, a northern limit somewhere south 



of Melville Bay 



Southern types with a northern limit 

 within the district in question

The chief results arrived at by this investigation are therefore: — 



(1) Many species, the northern limit of which was hitherto 

 supposed to lie between 69° and 71° N. lat. in reality occur further 

 north between lat. 71° and 73°. On the other hand, of the species 

 {Archangelica and its attendant species) peculiar to the southern part 

 of Disco, not one has been found further towards the north. 



(2) A decidedly southern, hemiarctic element is found in the 

 tlora even as far north as lat. 71° — 73°; more particularly, but not 

 exclusively inland around the head of the fjords where the climatic 

 conditions are more favourable.
