Unknown to us. Pfeiffer 's description and figure are 

 copied. It seems to differ from reticulata only by the larger 

 size, and it may possibly be identical with orientalis. We 

 follow Newcomb in subordinating the form to A. reticulata. 

 Mr. Thwing reports conspersa from near Lihue, remarking 

 that it approaches A. reticulata. His translation of Pfeiffer's 

 description of the colors is faulty. 



256. A. reticulata dispersa n. subsp. PI. 29, figs. 5, 6, 7. 



Dark chestnut with a columellar yellow patch, profusely 

 variegated with light yellow or white, in broken streaks, 

 stippled spiral lines or short vermicular spots, frequently 

 absent below the periphery, or rarely markings may be absent. 

 Last whorl sometimes having a light brown ground. Spire 

 short, obtuse, with very convex outlines. Embryonic whorls
