At Kaggowasar on Moon have been collected Acidaspis marklini 

 Angelin, Bumastus barriensis Murchison, and Proctus cf. P. verrucosus 

 Lindstrom. 



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

 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
