1717 E: fidelis 
Humboldt and Shasta Co., Cal., to Vancouver Island. 
‘Helix (Aglaja) fidelis, Gray.—I have received from Washing- 
ton Territory, a very large and fine variety of this species, which 
is entirely white, save a dusky area around the umbilical region. 
In every other particular, it accords with the magnificent typical 
specimens found there. As I had noticed upon living examples of 
this species, and of the H. infumata, particles of pitch or resin 
adhering to the shells, I naturally concluded that these mollusks 
inhabited the pine trees. In answer to my inquiry as to the sta- 
tion and habit, my friend replies: ‘H. fidelis is a tree-climber, 
ascending the trees to a height of 30 or 40 feet. We capture them 
in May and June when they are depositing their eggs in the damp 
moss at the roots of trees and other favorable places.’ As neither 
Mr. Binney nor Mr. Bland had seen the albino variety of this 
shell, until I sent it to them, and as it may be new to other col- 
lectors, I put it upon record in this manner.’’—A. G. Wetherby,

1724 Epiphragmophora circumcarinata 
“Or near Columbia, Tuolumne Co., Cal.’’ (see Nautilus 16: 
61, 62). 
“Helix, variety circumcarinata. Shell widely umbilicated, 
discoidal, flattened, angulated, with a peripheral keel; whorls 
6-6 %, slightly tabulated near the sutures, which latter are deeply 
impressed; surface finely granulated, varying in different speci- 
mens; and otherwise sculptured by conspicuous sub-acute ribs 
parallel with the lines of growth both above and below, which 
meet, and sometimes cross, the peripheral keel; these ribs are 
more or less irregular and uneven, of varying prominence, and 
are also unequally spaced, being closely crowded in some places 
and farther apart in others. Aperture obliquely subangulate, 
semilunate; peristome moderately thickened, reflected somewhat, 
covering the open umbilicus, and made continuous by a connecting 
thin deposit of callus on the labium. Color, in some specimens,
