This subspecies is easily distinguished from the others by its brown 

 suffusion on the last turn, in which respect it recalls Cochlostyla 

 (Hypselostyla) cincinniformis ultima, which also comes from Golo 

 Island but probably from another locality. The dark-brown bands 

 in this race will easily distinguish it from the bright reddish-brown 

 band of C. (H.) cincinniformis ultima.

Shell broadly ovate. Nucleus and the early postnuclear whorls 

 milky white. Beginning with the second postnuclear whorl, the 

 brown band at the summit makes its appearance, first as a light faint 

 brown line gradually increasing in width and intensity. What is said 

 of the line at the summit also holds good at the peripheral zone, which 

 shows partly above the suture. There is a broad dark umbilical area 

 corresponding in intensity of coloration with the peripheral band and 

 the band at the summit on the last turn. The spaces between these 

 zones are milk-white, and so is the inside of the aperture and the outer 

 lip and the columella except where the dark bands show through. 

 The periostracum where present is pale straw color, and in the case of
