156 ACHATINELLA BULIMOIDES. 



A small lot from Waimea 'oonsasts of forms figs. Id, \g and 



In Waialee the color-form fig. Ic occurred, but only dead 

 shells 'are in the lot taken by Gulick in the early Fifties, so 

 it was probably extinct there at that time. 



Across the range, near the head of Kaipapau (pi. 33, figs. 

 3 to 3d, coll. by Mr. Spalding), there is a colony having some 

 patterns identical 'with Kawailoa bulimoides. The embryonic 

 shell is usually dull purple ; last whorl variously banded with 

 dark chestnut and white, or yellowish-brown with or some- 

 times without bands; sutural border white or like the ground 

 color. The lip is white or sometimes dark-edged; and in a 

 large series taken, it is invariably dextral. This form has been 

 called vidua by some collectors, but I believe erroneously. It 

 is a slightly modified bulimoides, and not, I think, so closely 

 related to the Bulimellas of Kaliuwaa -as to those across the 



mam range. 



Mr. Gulick had this form from an adjacent locality. One 

 dead shell labeled " Hauula/ ' pi. 33, fig. 4, is now no. 92445,

In Kaliuwaa valley and the ridge eastward along the Castle 

 trail, several colonies have been found by Messrs. Spalding, 

 Thurston and others, which 'are not directly referable to ovata, 

 obliqua, oomorpha or spadicea, while they belong to the same 

 group of local races. The shell is either sinistral or dextral; 

 an obesely ovate shape prevails; embryonic whorls are invar- 

 iably colored, usually chestnut, darker than in ovata and ob- 

 liqua; the lip-callus is rather narrow and the lip is narrowly 

 chocolate-bordered outside and within. The color varies in 

 different colonies, as follows:

 valley, where the Castle trail passes over the crest into Kaliu- 

 waa, a pure colony lives in a clump of ieie. The color is pale 

 grayish blue-violet (Ridgway, pi. 35) varying towards lav- 

 ender or pearl blue in different examples, suture bordered
