Partulina winniei BALDWIN, Nautilus, xxii, p. 67, November,

"Named in honor of Miss Winnie of Wailuku, Maui.' 

 Figured and described from cotypes sent by Mr. Baldwin, who 

 states that it is the counterpart of Partulina theodorei Bald, of

 think winniei a diminutive relative of P. perdix. It approaches 

 Perdicella in structure of the columella.

 pressed lines, columella plicately twisted, rather callous, 

 whitish, painted and varigated throughout with olive-brown, 

 sutures and columella white' (Reeve).

The apex (1 to 1^ whorls) is brownish white; the next one 

 or 1 J w r horls have broad protractive alternating stripes of snow- 

 w r hite and dark brown. The neanic whorls following have 

 narrow stripes of the same colors, running with the growth- 

 lines. This pattern may continue upon the last whorl, or the 

 stripes may become wider and bisinuate or angular there, with
