with unequal longitudinal striga^ of white shading into oach other, 

 white at suture ; spire acute, elongated ; whorls seven, moderately 

 convex, the last not quite two thirds the length of the shell ; ai)er- 

 ture less than half the length of the shell, obliquely subovate, lip 

 soon becoming revolute, broadly so in front, rising, a little nar- 

 rowed by a somewhat abrupt curve upon the columella, and ex- 

 panding again as it rises, until the two extremities of the lip nearly 

 meet ; the eolumellar portion stands off from the body whorl, dis- 

 playing a large umbilical fissure ; lip white, with a brown submargin 

 at the point of reflection. 



Length, If inch ; breadth, f inch. 



Inhabits California. Maj. Rich. 



This shell has very much the appearance of B. Lobhii Reeve, 

 from Peru ; but the aperture is larger and differently proportioned ; 

 the colors are less bright, the stripes broader and more blended. 

 B. pallidior 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. 



This is Gould's description. His figure is given in the 

 plate referred to. I have not seen the shell. 



EXTRA LIMITAL.-^ 



Bulimus chordatus Pfeiffer, 

 Hmnholdti Reeve, 

 Mexicanus Lamarck, 

 Zebra Miiller, 

 Ziegleri Pfeiffer, 

 have been detected in Cinaloa. 

 Bulimus vegetus Gould, was found at San Juan, Gulf of California, 



(Bost. Journ. vi. 375). 

 Bulimus vesicalis Gould, (1. c. Oct. 1853) "inhabits lower Cali- 

 fornia." This name being preoccupied by a species described by 

 Pfeiffer, (March, 1853,) Gould suggests sufflatus in its stead. 



1 Bulimus Laurtntii Sowerby, var. /3, is mentioned by Pfeiflfer (Mon. Hel. Viv. ii. 

 218) as inhabiting " Sitka littoris Aniericse occidentalis." Wlietlier he refers to 

 the Sitka of the northwest coast, or some South American locality, I do not know.
