Shell elongate-ovate. Nuclear whorls pale brown, the succeeding 

 whorls milk-white, banded with bright chestnut-brown and almost 

 blackish-brown spiral zones. The spaces between the dark zones on 

 the base are buffish yellow. The interior of the aperture is bluish 

 white, which is also the color of the peristome and the inner lip. 

 Nuclear whorls 2, well rounded, forming a depressed spire. The 

 postnuclear whorls are inflated, appressed at the summit, and marked 

 by very fine retractively curved lines of growth and microscopic spiral 

 striations both on spire and base. The aperture is almost circular, 

 oblique; the peristome is slightly expanded and reflected, and the 

 columella is slightly excavated. The parietal wall is covered by a thin 

 callus. 



The type (U.S.N.M. no. 314080) was collected by Mr. Quadras at 

 Sitio Pamulon, Mansalay Bay, Mindoro. It has 5.5 whorls and 

 measures : Length, 41 mm ; greater diameter, 30.4 mm ; lesser diameter, 

 27.4 mm. 



Another specimen (U.S.N.M. no. 20399), obtained by the Explor- 

 ing Expedition, which I am referring here and which bears no locality 

 label, has 5.4 whorls and measures: Length, 37.5 mm; greater 

 diameter, 28 mm; lesser diameter, 26.3 mm. 



In addition to this there are two young specimens (U.S.N.M. no. 

 7589), also collected by the Exploring Expedition, and four young 

 specimens (U.S.N.M. no. 255818) collected by myself on a hill on 

 the western shore of Mansalay Bay. This race is readily distin- 

 guished from the other two by its more elevated spire. It has the 

 dark base and variable bands of the typical race.

Shell broadly ovate. Nuclear whorls pale horn color; postnuclear 

 whorls white, the first with a median brown band, which on the last 

 whorl is almost black. A similar dark band is at the periphery and 

 two on the base. The columellar area is likewise almost black. The 

 spaces separating these bands on the base are pale straw yellow.
