revolving, dark-brown lines. One specimen shows ten, but five 
of these are somewhat obsolete and close together near the 
narrow anterior portion of the shell. I have found living speci- 
mens at St. Augustine, Fla., in which the blotches were a light 
rose-pink, with the six revolving lines of a similar color. Dr. 
Dall records, from Belize, a pale salmon-colored specimen with 
the lines obsolete. The species varies in length from 65-85 mm. 
It ranges from North Carolina to Florida and westward to 
Mexico. 
THREE NEW ALPINE VERTIGOS FROM CALIFORNIA. 
BY S. STILLMAN BERRY. 
Among numerous Pupillidae collected from the higher moun- 
tain regions of California during the past few years appear 
several apparently undescribed forms, diagnoses of three of 
which are given below. 
VERTIGO MODESTA MICROPHASMA, new subspecies. Figs. 1-6. 
The shell is cylindro-conic, rimate-umbilicate, thin, very 
pale horn color, by transmitted light transparent and colorless. 
The surface is glossy and distinctly irregularly, obliquely 
striate, especially on the upper whorls. The spire tapers from 
the last whorl, at first gradually, then more rapidly, to the 
obtuse apex. The whorls are strongly convex, the last with an 
indentation just back of the aperture over the lower palatal 
tooth, subsequently with a narrow, abrupt, axial constriction, 
then swollen to form a low, wave-like crest just back of and 
parallel to the lip. The aperture is rounded triangular, scarcely 
constricted on the outer margin, the peristome thickened and 
porcelain white in color, showing through the back of the shell 
as a white line, but the sharp lip scarcely reflected except over 
the columella. The posterior angle of the outer lip curves in 
rather sharply to the body whorl. The number of teeth varies 
from 2 to 5. The palatal and columellar lamellae are always 
well developed. In addition there is almost always a well 
developed lower palatal. A smaller, but variable upper palatal
