314 ACHATINELLA SWIFTII. 



cimen, is white, streaked with light purplish gray at and above 

 the periphery, cut by white spiral lines. There are several 

 narrow black-brown bands and lines on the base, and two 

 above. Sutural border slightly tinted. 



A large lot in the Gulick collection shows wide variation in 

 pattern and color. The ground is often yellowish or yellow at 

 the base. Blackish or chestnut spirals or pale streaks may 

 predominate. Profusely banded specimens come close to the 

 banded forms of A. leucorraphe. Others run directly into 

 flavida and swiftii. Some are figured on pi. 58, figs. 9 to 9b, 

 11, 11, Kalaikoa, Gulick coll. 



Forms closely resembling Mr. Gulick 's tuberans were col- 

 lected by Mr. Spalding much further southeast. 



A lot from the summit of the southeastern ridge of Kipapa, 

 pi. 58, figs. 4, 4a from no. 3652 of Mr. Spalding 's collection, 

 consists of dextral and sinistral shells. The white apex has a 

 dusky tip, and usually an ochraceous band above the suture 

 of the embryonic whorls, the rest of the spire being white, or 

 with a cinnamon or brown band or line below the suture. 

 The last whorl is grayish olive with a white band or bands, or 

 the grayish tint may appear only in bands at periphery and 

 base. Lip and columellar fold have a pale lilac tint. Some 

 of these shells are very short in contour. 



Length 18, diam. 12.7 mm. 



Length 17, diam. 11 mm. 



Length 15, diam. 11.8 mm. 



A lot from one of the minor spurs between the terminal 

 branches of the Kipapa-Waiawa division ridge, pi. 58, figs. 5, 

 5a, 56 from no. 2266 Spalding coll., consists largely of shells 

 similar to the preceding, but there are some like those figured, 

 in which black lines or bands are superposed over the other 

 pattern ; sutural border cinnamon ; lip lavender to lilac. There 

 are also some transitional specimens between these patterns, 

 with the dark bands narrow and rather olivaceous. It is these 

 shells which are nearest to Gulick 's tuberans. In a lot of 143, 

 all are sinistral. Length 18, diam. 13 mm. 



Dr. Cooke took a very pale form of "tuberans" on a "low 

 ridge in Wahiawa", pi. 58, figs. 3, 3a. They resemble some of 

 Mr. Spalding 's Kipapa shells.
