throughout, dilated at the columella insertion and almost covering 
the umbilicus. Alt. 12°5, greater diam. 20, lesser 16°2 mm. 
Belongs to the E. rowelli group, but differs from other species in 
its malleation. From tudiculata and its allies, it differs widely in 
the elliptical mouth, coarse apex and fewer whorls. The same 
characters and its sculpture remove this shell from E. traskii and 
its several varieties described by Hemphill. 
Locality, “San Juan del Norte” (Gabb). Probably on the east 
coast of Lower California. 
NOTES AND NEWS. 
VARIATIONS OF PLEUROCERA ALVEARE Conrad.—In L. and 
F.-W. Shells, part 4, (Strepomatide), page 50, Mr. Tryon says: 
“The species is very variable in length,” leading one to infer that 
the other features were more constant. Such is not the case. 
Specimens from Cypress and Shoal creeks, Ala., present such a 
difference that on first sight the mature shells of one stream would 
not be taken for the same species as those from the other. 
From Cypress creek they have the folds or tubercles on each 
whorl and the striz on the base well defined. From Shoal creek 
they are eroded on the spire, giving the shell a cylindrical appear- 
ance; body whorl smooth and the striz of the base faint or want- 
ing; a number from both streams are two-banded; the upper band 
causes the dark spots Mr. Lea mentions in his description of perno- 
dosa. In both streams they were found on rocks in the current.—

New Locarity ror Unto Exuipsis Lea.—While collecting in 
the vicinity of Florence, Alabama, the past summer, eight speci- 
mens of this species were found in the Tennessee river—A. A. 
Hinkley. 
Mr. Epw. W. Roper, of Revere, Mass., gave his friends in 
Philadelphia and Washington a short but pleasant call recently. 
Z. CELLARIUS IN WesTERN PennsyLyANiA.—I found 3 speci- 
mens of Zonites cellarius Miill., 2 living and 1 dead, from the Phipps 
Conservatory in Allegheny City, and as the 3 specimens came from 
3 different greenhouses, they must have obtained a pretty good 
foothold. None of the shells were fully mature, the dead one being 
the largest— Geo. H. Clapp. 
Tue Rare or Growru or Herices.—I have placed mature 
Helix appressa in a box the middle of May. They have laid eggs,
