ULRICH (E. O.) and BASSLER (Ray S.)— Continued 



Kloedenella new genus, (ienotype Kloctieula Pcnnsylvniiica Jones. 



The genus includes some 8 to 10 species, two of them probably only varieties rang- 

 ing in time from the Clinton to Middle Devonian. The British species Beyrichia ? 

 hicaesa J. &. K., may be included. 



This genus is divisable into two sections: 



In the first, the genotype, the posterior and inedian furrows arc shorter than in sec- 

 tion number 2, ami the anterior furrow either wanting or more or less wcIl-dc\eloped. 



In the 2nd section, of wiiicli Hryr'uliia llalli Jones, is a good example, the posterior 

 and anterior furrows are long, subetjual and extending nearly or quite across the valve. 



Kirkbyina new genus. Genotype Bcyrichirlln !' nticosa Jones and Kirkby. 



Kirkbyina resembles Primitia, but is readily distinguished by its overlapping valves 

 and thicker anterior end. 



Beyrichiella J. & K. Genot\pe B. cristnta J. & K. 



The shell is relatively longer than that of Kirkbyina, and its larger valve is not 

 the right, as in that genus, but the left. 



The authors include luider Beyrichiella B. crisltita and K irkhynui anncctcns the t\pe 

 of Synaphe Jones and Kirkby, also Ulriciiia coriflucns L'lrich. 



The generic term Synaphe was used by Iluebner, therefore preoccupied. 



Beyrichiopsis J. & K. Genotype, B. fimhriata J. & K. 



Other typical species are the Carboniferors species: 



Beyrichiopsis coniiiUi, B. siihJnitatti, B. forfif. B. i^ra/iiiltil/; and /}. simplex, all de- 

 scribed by Jones and Kirkby.
