TROCHOMORPHA. 133 



spots of a luteous-white color, will at once distinguish it. The 

 upper surface is colored nearly the same as T. merziana, a Solomon 

 Island species ; but the present species may be separated by the 

 absence of the basal band, darker color, the narrower last whorl, 

 and its narrower aperture. T. merziana also differs in having the 

 upper margin of the peristome inflected. (Garrett.)

This species, of which Garrett's types lie before me, is allied to T. 

 planoconus, but differs in the color of the base, larger umbilicus, 

 and broader contour. The last whorl is notably convex above on 

 its latter part. The umbilicus readily exhibits all of the whorls, 

 and measures about one-seventh the diameter of the base.
