is similar to none of them except the E. t. subdolus of Hemphill. 

 Specimens fivjm Hemphill's original material are now before me, and 

 undeniably evidence a close relationship, but the Redlauds specimens 

 differ very constantly in their warmer, brighter coloration, much 

 broader and darker color band, swollen base, obese spire, and less 

 spreading outline. A few of the shells show a tendency to approach 

 stthdolus in one or more of these features, but the majority of these 

 are immature or ajijiear more or less pathologic in .some way. Normal 

 specimens so far as seen are quite uniform. 



This is the common Helix of the hills about Redlnnds. being especi- 

 ally abundant in the Heights region of the city, where the orange 

 orchards cease and the chaparral begins, but from other localities I 

 have not seen it. The race of ludiculata found in the neighboring 

 mountain caiions appears subspecifieally different, and. curiously 

 enough, seems to re.semble the typical coast form much more nearly 

 than it does either riifitrrrac or suhdoliis. 



Polygyra pinicola, new species 



Shell small, roundly conic, thin, covered copiously with numerous 

 small, slender, epidermal hairs, arranged almost quincuncially in lines 

 oblique to the very weak lines of growth. Embryonic whorls at first 

 nearly smooth, then finely radially wrinkled, and .showing a sculpture 

 of small elongate granules. Spire low, somewhat convex, sutures im- 

 pressed. Whorls about 5i/o. Body whorl almost angled at the first 

 third, deeply constricted back of the peristome, the base swollen and 

 rounded; very slightly descending in front. Lip white, thickened and 

 reflexed, but not very wide; narrowed l)elow the ])illar. then again 

 flaring .slightly so a.s partially or even entirely to close the minut(\ 

 scarcely permeable umbilicus; lip sometimes with a slight extra thick- 

 ening at the base, otherwise without evidence of teeth ; upper and 

 lower ends connected by a barely perceptible wash of callus. CoU)r 

 a light brownish horn, without trace of a band.
