* This is an exceedingly rare species, but two specimens 

 having come under my observation, one of which serves for 

 the illustration, the other in the cabinet of the late Hugh 

 Cuming, in London " (Newc.). 



This species seems close to A. terebra var. longior of West 

 Maui, a dextral shell. 



Shells from Ukumehame, West Maui (pi. 15, fig. 11), sent 

 by Mr. D. Thaanum, agree well with Newcomb's figure of the 

 type of fusoidea. They are buff with faintly darker streaks, 

 having wide light-brown stripes on the last embryonic whorl. 

 Under the lens the surface is weakly plicate, as in P. terebra 

 longior. Length 17, diam. 8 mm.

 pi. 7, f. 36, 1856. 



The sculpture of impressed spirals and dense, fine, pro- 

 tractive wrinkles or ripples is very clearly developed. The 

 color is yellowish-green (tawny-olive of Ridgway's Nomen- 

 clature of Colors) , but in the young there is often more of a
