SONORELLA FISHERI new species 

 (Plate XXXIII. figure 3) 



Epiphragmophora magdalenensis (in pari) Dall, Proc. U. S. Xat. Mus., 

 vol. xix, p. 339, 1896. 



Epiphragmophora magdalenensis (in part) PiLSBR'i and Johnson, Nauti- 

 lus, p. 59, 1897. 

 Shell small, depressed, horn-colored, with a moderately broad 

 chestnut band edged by a scarcely perceptible lighter zone encircling 

 the whorls a little above the periphery. This band is covered by the 

 succeeding turns in all but the last one and one-half volutions. The 

 nepionic stage embraces about one-half of a whorl, is rather de- 

 pressed, and quite strongly transversely wrinkled. The neanic stage 

 consists of one and one-third turns, which have been described in the 

 definition of the section. Ephebic whorls two and one-half, de- 

 pressed, moderately well rounded, a little more convex below than 

 above, marked by many strong, wavy, and wrinkled incremental lines 

 and numerous almost round, raised papillre which form oblique, 

 curved, interrupted lines extending from the summit of the whorls 

 forward and downward, and are equally strong between the sutures 

 on the periphery and the base; in the umbilicus, however, they are 

 much heavier, assuming a warty appearance. The last whorl is grad- 

 ually but considerably deflected at the aperture. Aperture moder- 

 ated large, rounded oval, very oblique, scarcely at all expanded. 

 Columella slightly expanded at base and but slightly reflected over 

 the umbilicus. The type (No. 123,579, U. S. Xat. Museum) and 

 type lot and another lot (No. 123.578) were collected by Dr. A. K. 

 Fisher and E. W. Nelson on the Death Valley expedition at Johnson 

 canon, Panamint valley, California, at an altitude of 6,000 ft. The 

 type measures : maj. lat. 15.5 mm., min. lat. 13 mm., alt. 8 mm. ; aper- 

 ture : maj. lat. 7 mm., alt. 6.5 mm.; umbilicus about 1.8 mm.
