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 VEKTIGOS 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
