Partulina redfieldi

(Original description) The shell is sinistral, elongate, conical, and longitudinally striated. It is light fawn in colour, passing into deep chestnut, and is paler above. It is either plain or bears transverse chestnut bands with obscure undulations on the third whorl only. A white band also traverses the suture. There are six whorls, separated by a well-impressed, slightly marginate suture. The aperture is subovate. The columella is brown, flat, and twisted. The lip is slightly reflected and has the same colour as the columella. The length of the shell attains 25.4 mm; its diameter 11.43 mm. Partulina redfieldi appears in various colors, and the shells are found to be polymorphic, exhibiting a wide range of white to brown shades with varying numbers of white or brown bands. Partulina redfieldi must reach 3 to 5 years of age before it can reproduce and are only capable of producing up to 5 babies every year. The snail has a juvenile mortality rate of 42%.

Partulina redfieldi are endemic to the island of Molokai and Maui Hawaii. This species is commonly found on the smooth leaves of the 'ohi'a lehua tree, Metrosideros polymorpha, also endemic to the Hawaiian Islands.
