LAND AND FRESH WATER SHELLS OF N. A. [fART I. 



Jaw with about thirteen separate plates, the outer longitudinal 

 edge of each thickened into costse ; coarse transverse stria). 



The abov'e is Gould's description. There can be no doubt of 

 the identity of his species with B. jpallidior. 



Fig. 340 is a fac-similc of that of Dr. Gould. Fig. 341 is 

 from a specimen collected by Mr. Xantus.

Blilismiliis excelsMS, Godld. — Shell ovate-fusiform, rather solid, 

 smooth, ]iale coffee-colored, witli unequal longitudinal strise of white 

 shading into each other, white at suture ; spire acute, elongated ; whirls 

 seven, moderately convex, the last not quite two- 

 Fit^ 0-12 thirds the length of the shell ; aperture less than 

 half the length of the shell, obliquely subovate, peri- 

 stome soon becoming resolute, broadly so in front, 

 rising, a little nan owed by a somewhat abrupt cui've 

 upon the columella, and expanding again as it rises, 

 until the two extremities of the peristome nearly 

 meet ; the columellar portion stands off from the 

 body-whirl, displaying a large umbilical fissure; 

 peristome white, with a brown submargin at the 

 point of reflection. Length 43, breadth 18 mill. 

 Inhabits California and Lower California. 

 This shell has very much the appearance of Z?, 

 lobbii, Reeve, from Peru ; but the aperture is larger 

 and differently proportioned ; the colors are less 

 bright, the stripes broader and more blended. B. 

 Bulimulus excelsus. palliJior, Sowerby, has the aperture more like it, 

 but is colorless, and has the spire less elongated. 

 In form it is also much like B. xanthostoma, D'Orb. It has the form of B. 

 memhranaceus, but is much larger and thicker.
