counties, California, but the specimens from these two localities 

 should be reexamined as it seems probable that the one from Inyo

 from San Diego county may belong to S. indiocnsis Yates. 



Group of S. hachitana 



SONORELLA ASHMUNI new species 

 (Plate XXXI, figure 5) 



Shell like 5\ hachitana Dall, but larger in every way. General 

 coloration light isabelline above and whitish below ; a broad chestnut 

 band, bordered on each side by a light zone, encircles the whorls 

 somewhat above the periphery and may be seen above the suture on 

 all the ephebic whorls; the band gradually diminishes in breadth from 

 the aperture toward the apex. The nepionic stage embraces the first 

 half turn, is somewhat flattened, and slopes outward; it is marked 

 by a few transverse wrinkles and passes without distinct separation 

 into the neanic stage, which is described in the definition of the group. 

 The neanic portion consists of one and one-quarter turns ; its termina- 

 tion is marked by several strong, transverse wrinkles. The ephebic 

 stage consists of three and one-eighth moderately rounded, pol- 

 ished whorls which are marked by numerous lines of growth and 

 here and there by a few obsolete, very distantly and irregularly scat- 

 tered, rounded papillse. Last whorl considerably deflected at the 

 aperture, which is large and oblique and has the outer edge expanded 

 and somewhat reflected ; columella broadly expanded at base, re- 

 flected only slightly over the umbilicus, which is moderately large 

 and open to the very apex; parietal wall covered by a thin callus. 

 The type (No. 151,450, U. S. Nat. Museum) was presented by the 

 Rev. E. H. Ashmnn, after whom the species is named. It was col- 

 lected at Richinbar, south of Prescott, Arizona, at an altitude of 

 3,500 ft. Tt measures: maj. lat. 28.2 mm., min. lat. 23.2 mm., alt. 

 16.9 mm.; aperture: maj. lat. 15.2 mm., alt. 13 mm.; width of um- 

 bilicus, about 4 mm. 



Another lot (No. 152,125, U. S. Nat. Museum), collected at 

 ("erome, Arizona, was received from the same gentleman.
