At Kaggowasar on Moon have been collected Acidaspis marklini 
Angelin, Bumastus barriensis Murchison, and Proetus cf. P. verrucosus 
Lindstrém. 
At Orrasaar on the east coast of Oesel, about 150 yards north of the 
post station, occur many blocks of a marly semicrystalline, yellowish 
gray dolomitic limestone which contains numerous small fossils. The 
blocks were probably pushed up by the ice from beneath the sound

the same horizon as the rock at the base of Igo Pank. From these 
blocks have been obtained: — 
Lyellia tubulata Lonsdale. 
Favosites gothlandicus. 
Ptychophyllum patellatum. 
Wilsonia wilsoni.

On the island of Schildau between Moon and the mainland the same 
sequence appears to obtain as on Moon, but somewhere in the lower 
beds there is a level containing many fine fossils similar to those of 
the locality at St. Johannis described in the next paragraph. I did
