flected somewhat, covering the cpen umbilicus, and made <ontin- 
uous by a connecting thin deposit of callus on the labiura. Color, 
in some specimens, dingy white to white, in others a dingy red- 
dish white,ornamented with a double revolving band,--the upper 
‘stripe being whitish, the lower reddish or light chestnut just 
above, and contiguous to the peripheral keel; the pinch or fold 
of the keel taking up what in Helix Mormonum is the third 
~ or lower stripe of white. Number of specimens 4, 2 adult and 
2 immature, but nearly full grown. Dimensions—Greater dia- 
Eeneter .92-1.01; lesser diameter, .75-.86; height .36-.37 inch. 
Animal not observed. Habitat, Stanislaus county, near Tur- 
Joch, California. For the specimens from which the above is 
written, I am indebted to Mr. A. W. Crawford, of Oakland, 
who has examples in his collection; specimens are also cui 
tained in the typical collection of my friends Binney and Bland, 
and in my own museum. Most authors would reéard the above 
as a distinct and well marked species; I regard it ( as well as H. 
Hillebrandi, of Newcomb) es a varietal form of Helix Mor- 
Monum, to which it is a near neighbor, inhabitating the 'sanie 
‘region. —-Rolert E. C. Stearns, Annals N Y ac eS
