Publisher's Synopsis
Excerpt from The Lower Silurian Lamellibranchiata of Minnesota
The Lamellibranchiata agree with the Brachiopoda in having bivalved shells, but differ in having them, as a rule, equal and inequilateral instead of inequivalved and equilateral; they are, furthermore, placed on the sides of the animal (for which reason we distinguish them as right and left), instead of above (dorsal) and below (ventral). From the Gastropoda and Cephalopoda they are distinguished by wanting a distinct head, in having bivalved shells, a bilobed mantle and lamelliform gills developed in pairs.
