a new genus, which he names Michteria. They are not bivalved. 

 Probably Richter's Cytherina sti-iatula belongs to a new genus, whilst 

 his Beyrichia dorsalis is not a Beyrichia, but' probably a Primitia, 

 similar to P. Maccoyi,. To judge from Richter's figure, his Beyrichia 

 nitidula resembles some of the Cytheroids from the Scotch Coal Mea- 

 sures. F. AY. R.
