EXPLANATION OF PLATES. 
In some instances the very fine, closely crowded striation has been omitted, 
while in other cases where shown it has been exaggerated by the artist. Atten- 
tion is called to this under the explanation of the figures. The measurements 
cited after the names refer to the axial length of the specimen.
