"It is more fragile and less slender than P. attenuata, the 

 nearest allied form. The spire is less than half the length 

 of the shell, and the suture is margined by a white line. The 

 dull whitish peristome is widely expanded. The aperture is 

 never dentate, and the yellow- corneous shell is faintly tinged 

 with greenish. 



"The animal varies from pale luteous-yellow to light 

 brownish yellow. The soft parts, as seen through the trans- 

 parent shell, are mottled with slate-colored spots. The foot 

 is about the same length as the shell, and the ocular peduncles 

 are very long and slender." (Garrett).

This species resembles the preceding [P. lineata], but it 

 is distinguished by having the peristome less thick, by the 

 umbilicus, of which the crevice is obliterated. Its altitude 

 is 8 lines by 5 in diameter. Its spire is more swollen than 

 in the preceding. The shell is thinner, and entirely corneous 

 yellow. The Yellow Partula lives on the island of Borabora 

 (Lesson). 



Society Is.: Borabora (Lesson, Garrett, Voy) ; widely dif- 

 fused throughout the island, on the trunks and foliage of 

 trees and bushes. (Garrett).
