3. Typhochrestus spetsbergensis, Thor. (1). 
Six adult males, five adult females, and a number of 
immature examples. 
Klaas Billen, Prince Charles Foreland, Gips Valley. 
Also from Siberia, New Siberian islands (9); probably 
Greenland. 
4, Erigone psychrophila, Thor. (1). 
Two males only at Ebba Valley. 
Occurs also in Siberia and the New Siberian Islands (g) 
and Franz Joseph Land. 
5. Erigone arctica, White. 
Four males and two females at [Claas Billen.

species. 
Of a very wide range, including the British Isles, in many 
parts of which it is common.

FE. tirolensis occurs on the Grampians and Ben Nevis at 
high altitudes (11) ; also in Siberia and Nova Zembla (3), 
Tyrol, Switzerland, and ‘Tatra. 
7. Corypheus holmgrenii, Thor. (1). 
One adult male and seven adult females from Bear Island. 
This is certainly the C. mendieus, L. Koch (3), of British 
authors, and almost certainly Lophomma nivicola, Strand (6). 
Siberia, Nova Zembla (3), the north-east coast of Si- 
beria (8), the Scottish mountains at high altitudes (11). 
Mr. Elton did not find this species at Spitsbergen. It was 
the only one found at Bear Island. 
8. Micaria eltonii, sp. n. 
One adult male at Klaas Billen on August 9th, 1921. 
This appears to be undescribed, and I have great pleasure 
in giving it Mr. Elton’s name. I must, however, state that
