I obtained numerous examples of this species at Vanua Balavo, 

 where it occurs on the trunks of trees. Dr. Graffe found it at 

 Kanathia and Oneata. Prof. Mousson has described the var. Jlavida 

 from Samoa. 



About the same size but thinner than H. sen/peri, and the spire 

 is more conical, and the last whorl more depressed, so much so as to 

 give the periphery an obtusely angular appearance. The peristome 

 is thin. Colour white or pale greenish yellow, frequently with a 

 dorsal spiral red zone ; basal callus greenish yellow.

Dr. Gould's t^pe specimens were obtained at Manna and Upolu, 

 Samoa Islands. Mousson's variety expansa was found by Dr. Graffe 

 at Kanathia and Viti Levu. He also described the small var. 

 diminuta i'ron» the Tonga Islands. Pfeiffer erroneously cites the 

 Sandwich group as one of its localities. 



This species, which lives on the ground in forests, may be dis- 

 tinguished by its thin, smooth, shining shell, convexly conoid spire, 

 angular and conspicuously carinated body-whorl. The peristome 

 is thin and expanded, forming an angle at the point of union with 

 the columella. Colour pale corneous, white, or light sidphur-yellow, 

 with longitudinal flexuous reddish or white narrow stripes. Diam. 

 4 to 9 millim.
