ACHATINELLA BUDDII. 187 



Soc. N. H. coll.). Also white, of the ordinary phaozona 

 shape and size, in contour like pi. 24, fig. 11. No tree snails 

 are now to be found on this peak. Mr. Gulick notes the fol- 

 lowing patterns. "Var. 1. White with one or two broad 

 black bands at the base. Var. m. Elongate, white with two 

 black bands, one revolving above the suture, the other enter- 

 ing the aperture, and sometimes a third accompanies the 

 sutural margin. Var. n. White with from three to five 

 crowded bands at the base. Var. o. Pure white." 



On the base-leveled plain north of Olomana, about half a 

 mile from the sea southeast of Kailua Bay, Mr. Spalding 

 found phceozona of normal size and marking in the humus 

 turned up by the plow in a grove of young coconuts, west of 

 the stream. While one would not expect land shells to with- 

 stand disintegration for many years, it must be a century, and 

 probably much more, since forest suitable for tree snails 

 existed in this place. It will be inferred from the planting 

 of coconuts that the plain lies only a few feet above sea level. 

 The situation is however a dry or semiarid one for the Koolau 

 side. East of the stream in this plain I have found rather 

 rich deposits of fossil land shells, including Amastra and 

 Leptachatina.
