\'0L. X] BERRY— SOME UNDESCRIBED CALIFORNIAN HELICES 63 



penultimate whorl where they are always strongly evident as 

 well as within the umbilicus and to a less degree over the 

 region just behind the aperture on the body whorl ; papillae 

 elsewhere on the last whorl more weakly developed. Spiral 

 sculpture obsolete, a few weak traces persisting on the upper 

 surface and peripheral region of the body whorl only. 



Color light golden brown near buffy citrine, paler and with 

 more of a yellow tone below, with a dark, liver brown band of 

 a width of about 1.0-1.5 mm. on the shoulder, bordered above 

 and below by a rather narrower band slightly lighter in tone 

 than the body of the shell.

 Coll 23.8 19.1 13.8 2.3 5V3 



Type: Cat. No. 4848, Berry Collection. Paratypes in the 

 collection of George Willett. (Neither specimen quite fully 

 mature. ) 



Type Locality: Monrovia Canyon, San Gabriel Mountains, 

 California; George Willett, March, r5l9; 14 specimens, for the 

 most part not quite mature. 



Additional Localities: In addition to the lot from which the 

 type was selected, the following specimens before me are pos- 

 sibly referable to the same subspecies. They are at any rate 

 very close, although the material is still inadequate for entire 

 certainty. 



Millard's Canyon, north of Pasadena, San Gabriel Moun- 

 tains, California; E. P. Chace, March 11 and June 3, 1917; one 

 living adult, one living juvenal, seven dead of various ages. 



Eaton's Canyon, north of Pasadena, San Gabriel Mountains, 

 California; E. P. Chace, September 3, 1917; two living adults, 

 six dead of various ages. 



West fork San Gabriel River "just below the divide", San 

 Gabriel Mountains, California; E. P. Chace, September 1,
