“Shell pale gray, beehive-shaped, with a blunt apex and 5% 
rapidly enlarging convex whorls; nucleus minute; subsequent 
whorls polished, finely spirally striate, crossed by very fine flexu- 
ous strie corresponding to the lines of growth, which more or less 
microscopically crenulate the interspaces between the spirals; 
suture not impressed; base with an obscure angulation peripher- 
ally, the sculpture similar to the rest of the shell but more pro- 
nounced; umbilicus narrow, deep; aperture subquadrate, oblique; 
the pillar thin, white; the throat pearly. Height of shell 13; of 
last whorl 10; maximum diam. of base 14 mm.’’

3073 Pecten (Pseudamusium) Arces 
‘Shell hyaline white, with no anteriorly or convex hinge, line 
rather long, ligament and pit very small, entire surface of convex 
valve sculptured with subequal radial threads and similar concen- 
tric threads, forming nearly square equal reticulations, about four 
to a square millimeter; the intersections are slightly prominent 
on the disk and more or less minutely spinose on the ends of the 
valve; beside these the entire valve is sculptured with minute 
equal radial lines, about six to a reticulation; the interior of the 
valve is glassy, the sculpture showing through. The flatter valve 
has similar sculpture, with a narrow smooth submargin, a cten- 
olium of five or six free teeth, a moderately deep byssal notch 
and five imbricated rays on the ear above the fasciole of the 
notch. Height, 35; length, 34.5; diameter, 6.0 mm.”’

3074  Cuspidaria subglacialis 
“Shell large for the genus, chalky, with a coarse dehiscent 
Olivaceous periostracum; equivalve, nearly equilateral. Beaks 
nearly in the center of the shell, anterior dorsal margin arcuately 
descending, anterior end of shell ovately rounded; posterior slope 
straight, or slightly distally recurved, with a short compressed 
distally gaping rostrum, terminally subtruncate; base arcuate, 
somewhat patulous below and behind the beaks, incurved at the 
beginning of the rostrum; hinge in the left valve with a small 
obliquely backwardly directed chondrophore; in the right valve 
there is also a strong lamina parallel with the dorsal margin and 
separated from it by a groove which receives the edge of the oppo-
