3072 Margarites simblus 



"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 strise 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." 



Type locality: — Off Santa Barbara, Calif. 



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-
