Some odd valves, named by Mr. Cuming, of this species (?) 

 have absolutely nothing to distinguish them from varieties of the 

 next species.

Among a large number of specimens of this species, obtained 

 by the naturalists of the Exploring Expedition, great variations 

 may be observed. Some of them are smooth and polished ; others 

 rude, coarsely striated with the lines of growth or radiating 

 stripe. The foramen is small and complete, with a wide and 

 solid deltidium ; while in others, of the same size, the foramen is 

 large, incomplete, and the deltidia widely separated. Some are 

 nearly twice as long as wide, others wider than long. Some are 

 distinctly trilobed, others are ovate and smooth. The mesial 

 ridge in the neural valve is usually present. Some of the spe- 

 cimens appeared absolutely identical with valves sent, as of the 

 last species, from ]\Ius. Cuming.
