examples smaller than the others, some of them not larger 
than the smaller form of oced/aris, but with no sign of the 
red band diminishing; the females differing little from the 
males in the colouring of the underside. This was the case 
also with those from Tromsé, but in a less degree, and even 
the Trondjhem example had no approach to the pale banding 
of Central-European females. 
7. Erebia medusa, var. polaris. Some approaching typical 
medusa, and only a few near polaris as described, which is 
therefore an aberration rather than a constant variety. The 
whole series however with a different facies from that of an 
equal series of Central-Huropean specimens, and, unlike the 
southern form, entirely without Asiatic neuration. 
Dr. CHapMAN remarked that Hrebia embla as taken at 
Seterstéen and #. disa as taken at Bossekop, had all the 
characters of distinct species. The male appendages were 
very constant in each form, and as described in the Trans- 
actions for the present year, p. 228. In #. embla the spines 
were confined to the head, in #. disa they extended along the 
whole of the neck; the appendages were also definitely 
smaller (5 to 6) and of a darker (denser ?) chitin. 
The ova were also distinct as follows :—
