Vol. X] BERRY— SOME UNDESCRIBED CALIFORNIAN HELICES 61 



Color a warm golden brown, running fairly near a tawny- 

 olive, becoming a little paler and yellower on the base, and

 about 1.5 mm. on the shoulder, bordered above and below by a 

 rather narrower band of a few tints lighter than the body of 

 the shell.

Type: Cat. No. 3905, Berry Collection. 



Type Locality: Altitude 2500 feet, near trail, south fork of 

 Warm Spring Canyon, San Bernardino Mountains, California ; 

 under logs; Allyn G. Smith, December 26, 1917; one specimen. 



Additional Localities: Alt. 3700 feet, near trail just south- 

 east of summit. Warm Spring Canyon, San Bernardino Moun- 

 tains, California; Allyn G. Smith, "December 26, 1917; two 

 specimens. 



Alt. 6500 feet, west wall of Bridal Veil Falls Canyon near 

 mouth, above Forest Home, San Bernardino Mountains, Cali- 

 fornia, in talus; E. P. Chace, May 24, 1918; nine fully mature 

 living specimens, several dead and young. (No. 3988 above are 

 part of this lot.) 



Remarks: This neat little helicoid is practically a miniature 

 race of the large E. petricola Berry ( :16, p. 107), with which 

 alone it would seem to require any special comparison. From 

 this it differs not only in its much smaller size, but also in its 

 thinner shell, more polished periostracum, and still further re- 

 duction of the spiral sculpture. It occurs in the same general 

 region of the San Bernardino Mountains as the typical form, 

 but has only been discovered at localities farther into the moun- 

 tains, at all of which it appears relatively constant and quite 

 sharply separable from petricola.
