L. TrasJcil, Newc. ? A dwarfed, very thin variety, showing 

 want of lime and heat, was found common by Harford and Dunn 

 last year between 5000 and 6000 feet elevation, in Mariposa Co. 

 It has but 4J whorls, and diam. 0*75, axis 0-30 inch, but the 

 form and faint revolving grooves distinguish the species, es- 

 pecially from other specimens of A. tudieulata of similar size 

 found with these, while the light corneous hue and height in- 

 dicate that it is not L. mormonum. It may be a thin northern 

 variety of L. Hemondii, but does not agree with the specimens 

 determined as Carpenteri by Dr. Newcomb, though I am in- 

 formed by Mr. Harford that Dr. Newcomb calls these by that 

 name. In flattened spire and rounded base many of them ap- 

 proach nearer to Lf Rowellii or LohriL 



L. Remondii, Tryon. 



This is to be added to our fauna if the specimens from the 

 peninsula and San Diego are really the same as the Guaymas 



* Several authors describe L. fidelis as red-banded, but the band is 

 really black, with red or yellow margins, that above often masked by the 

 pale color of the upper surface.
