Natica Lewisii, Gld.,=N. herculea, Midd. Puget Sound, J. G, Cooper, Suck- 
ley. “Shell sometimes remarkably globose, sometimes with spire much 
roduced.” W. C. “Abundant throughout the N.W. sounds, and col- 
ected in great numbers by the Indians for food. In summer it crawls 
above high-water mark to deposit its eggs” in the well-known sand-coils, 
which are “beautifully symmetrical, smooth, and perfect on both sides,” —

where it presents the same varied appearances as our eastern shell.”— W. C.

tenebrosa, Midd., and modesta, Phil., are probably vars. of ZL. Sitkana, Phil., 
=T. sulcata, Gld. |

the synonymy of which, reference is made to the Bri- 
tish Association Report.
