fascia, upper valve, median line linear, or acutely lanceolate ; costee 

 strong, sub-radiant. [PI. 10, a lower valve, bed upper do. upon 

 Macrocystus from the coast of Chili.] 



The upper valve has some resemblance to my Raphoneis scutel- 

 loides, which does not, however, appear to be a Cocconeis, as I have 

 never been able to discover a lower valve. Cocconeis Grantiana, 

 Greville, is perhaps the lower valve of a similar species, if not that 

 of a small form of C. scutellum. 



(I scarcely see how the upper valves differ from that of Campy- 

 loneis Grevillei, var. obliqua, f. 5 a, F. K.)
