Note. — Owing to an inadvertence the series of numbers representing the stations, beginning with 6050 and ending 
with 6099, is represented on the Register of Mollusks of the U. S. National Museum, where the types illustrating this 
paper are preserved, by a series beginning with No. 122 and ending with No. 171. The latter numbers also appear on the 
labels.
