92 NEW-YORK FAUNA — MOLLUSCA. 
MELANIA SUBULARIS. 
PLATE VII. FIG. 138. 
(STATE COLLECTION.) 
M. subularis, Lea, Trans. Am. Phil. Soc. Vol. 4, p. 100, pl. 15, fig. 30. 
Description. Body elevated, with an acute spire, regularly attenuated from the body-whorl. 
Whorls ten to twelve, quite flat; base angular; outer lip not regularly rounded ; suture sub- 
cancellate. 
Color. According to Mr. Lea, horn-color; in my specimens, the centre of the whorl had a 
broad revolving rufous band, becoming darker towards the tip: vicinity of the sutures chalky 
white. 
Length, 0-7 -—1-+2; of aperture, 0-2 -0°3. 
This species occurs along the shores of Lake Erie. Inthe numerous specimens which I 
collected, I was not fortunate enough to obtain a single perfect collection, and am indebted to 
Mr. Lea for a portion of the figure.
