222 Descriptions of New Species of Achatinella. 



Remarks. — Differs from A. plumata Nob. in the character 

 and arrangement of its colors, and from A. fulgens Newc. in 

 the absence of the white sutural band, and the two broad black 

 central bands which characterize that species. 



The specimens found in ISTiu do not present the green varie- 

 ties, but incline more to white ; and are also thicker and more 

 ovate in form than those found in Palolo. The average weight 

 of full grown specimens from Kiu is about 9.00 grains, that of 

 the Palolo specimens is 7.20 grains. 



I have six or eight dextral specimens belonging to varieties 

 d, e, g, and i.
