spire. A variety with a narrow subsutural and subbasal band 

 of a dark chestnut color on a pale greenish yellow ground is 

 not uncommon. 



Tahaa, at the southern end in several valleys ( Garrett) .

The pale subsutural band gives the shoulder an appearance 

 of angulation, which does not really exist. While the Tahaan 

 forms of the faba type differ but little from Raiatean faba, 

 yet their variation- forms are somewhat diverse, and the minor 

 differences noted above seem fairly 'constant. I have therefore 

 thought it best, in view of the minute specific subdivision of 

 Raiatean Partulae, to give subangulata specific rank.

The shell is like subangulata in shape, but it occasionally 

 has a small tooth on the parietal wall. The usual color is 

 pale yellow or greenish yellow, almost white towards the 

 summit, or more or less suffused with fulvous, with a white 

 or flesh-tinted lip. "A beautiful variety occurs which has a 

 wide median reddish chestnut band (fig. 1). A more common 

 variety is found with two narrow reddish chestnut bands" 

 (fig. 2) ; the summit in these is purple-black. "'Chestnut- 

 brown varieties are not uncommon. The rarest variety is 

 fasciated the same as the typical faba." (Garrett}. 



Tahaa, occurring in greatest profusion in the northeastern 

 part, but spread all over the island except in the area of 

 subangulata (Garrett).
