DESCRIPTION. 



Animal not observed. 



Shell globose-conic, imperforate, rather thin, wrinkled, 

 covered with minute and crowded granulations ; color red- 

 dish brown ; apex free from granules, rather blunt ; spire 

 elevated ; suture impressed ; w^horls six, convex, the last 

 quite large and rounded, falling towards the aperture, and 

 banded with reddish brown above the middle ; aperture 

 rather large in proportion to the size of the shell, very 

 oblique, transversely rounded, within showing the band ; 

 peristome simple, reddish ash color, thickened, reflected 

 slightly at the base, ends approaciied ; umbilicus entirely 

 covered with a white callus. 



Greater diameter, 31 ; lesser, 17 ; height, 12 mill. 



Geographical Distribution. I am not acquainted with 

 the exact locality of this shell, but am inclined to refer it 

 to California. 



Remarks. Tliis shell is figured by my father as a var. 

 of H. Nickliniana Lea. A reference to Mr. Lea's figure 

 and description will at once show it to be distinct, accord- 

 ing to the present notions of specific weight. Dr. Gould 

 refers it (Terr. Moll. iii. p. 26) to H. Calif or nien sis Reeve, 

 (Con. Icon. 661). It appears, however, to be distinct from 

 the shell there figured. 



In general outline it resembles H. Kcllcttii Forbes, Proc. 

 Zool. Soc. London, 1850, pi. ix, f. 2, as well as Reeve's
