A very small tooth is developed in some examples. The shells 

 correspond more closely to the southern variety hucculenta than to 

 the usual thyroides of the north. It appears, indeed, as Mr. Stone 

 has suggested -to me, that this form is a member of the Carolinian 

 fauna, which extends far to the northward in eastern New Jersey. 



Helix (Mesodon) albolabris maritima Pils. 



Many specimens from the vicinity of Cape May, N. J., have been 

 examined, collected by Mr. Witmer Stone and Prof. C. LeRoy 

 Wheeler. The) exhibit but little variation. I have also seen spec- 

 imens from a locality in Long Island, N. Y., and a form which Mr. 

 Bryant Walker tells me is quite similar, has been found in Michigan, 

 inhabiting a locality having much the same physical features as the 

 sand hills of Cape May.

PEELIMINARY NOTICES OF NEW FORMS OF FRESH WATER MOLLUSKS. 



BY H. A. PILSBRY. 



Vivipara georgiana var. altior Pilsbrv. 



Shell pyramidal, elongated, composed of 62 to 7 whorls, separated 

 by deep sutui*es. The whorls are flattened or sunken around the 

 upper portion, convex below, giving a decidedly cadaverous appear- 

 ance to the shell. Some specimens have a scaliform appearance. 

 The surface is marked with growth-lines and irregular wrinkles, 

 but some specimens show distinct spiral lirte. All of the specimens 

 seen (30 in number) are bleached, but some show faint traces of 

 reddish bands. The umbilicus is narrow, often a mere chink.
