" Shell depressed, orbicular ; spire conical or flattened ; columella 

 partly filled by a tongue-shaped callous process (funiculum) from

"Shell ovate to flattened globular; spire only slightly elevated, 

 obtuse; whorls three, slightly convex, body vrhorl having a long, 

 slightly convex slope from suture to near base, where it suddenly 

 turns under the umbilicus ; surface ornamented with fine, oblique 

 incremental lines ; suture distinct, but not impressed ; aperture 

 semilunar; lip thin; columella incrusted, the incrustation extend- 

 ing down, completely covering the umbilicus." *^ 



Dimensions: Length, 45; lat,, 48. 



Many of the young of this species are quite flat, the spire but 

 little elevated, if elevated at all. Var. AUa Dall is also found in 

 the same formation with the P. {Neverita) recluziana. The species 

 is very variable in both size and shape. 



This species is found in both the upper and lower series of the 

 Clallam formation at Gettysburg, Wash.
