Raphoneis scalaris. 



Valves lanceolate or elliptic, with striae trans- 

 verse, moniliform, generally somewhat radiant, 

 very distinct, with a more or less conspicuous 

 pseudo-raphe. Apices without nodules, often 

 showing fine scattered puncta. Girdle face 

 narrow, linear. 



The genus Raphoneis includes a large number of species, both living and 

 fossil, but very many of them appear to us to be only modifications of 

 R. amphiceros.
