which are subequal, and a much broader interrupted spiral zone of 

 irregular white blotches a little posterior to the periphery. The 

 peripheral portion itself being blackish brown, the white and dark 

 areas join their irregular patterns without losing their color intensity. 

 The basal ground color agrees with that of the upper surface of the 

 last whorl. The blackish-brown peripheral border of the upper sur- 

 face is also present on the lower. This is succeeded by an irregular, 

 broad white spiral area which is followed by four spiral white threads 

 of which the second is about one-half as wide as the other three, which 

 are equal. Another broad white area, equaling about one-third of the 

 width of the base, encircles the columella. The expanded portion of 

 the peristome is blackish-brown, tinged with reddish-brown at the 

 inner edge. The light color also spots part of the white columella 

 and in a little more intense form tinges the basal and parietal callus. 

 The inside is pale bluish-white with satiny luster. 



All the whorls are moderately rounded on the upper surface except 

 at the black peripheral band, where they become slightly excurved. 

 The basal portion of the last turn is well rounded and also lightly 

 excurved at the peripheral keel. Aperture broadly oval, oblique, 

 outer lip expanded and thickened; columella oblique, slightly con- 

 cave, reflected over the base as a thick callus, which extends weakly 

 over the parietal wall. On both surfaces the white spirals are im- 

 pressed as if inlaid. The entire surface is marked by exceedingly 

 fine, closely spaced striations, which cross each other at right angles 

 and the lines of growth at an angle of forty-five degrees. 



The type (Cat. No. 218402, U.S.N.M.) comes from Makabenga, 

 Nueva Vizcaya, Luzon. It has 5.2 whorls and measures — altitude, 

 33.2 mm.; greater diameter, 51.2 mm.; lesser diameter, 43 mm. 



This race 'differs from Cochlostyla schadenbergi schadenhergi in 

 having tlie lip and peripheral keel blackish-brown, instead of pale 

 brown. There are also decided differences in tlie light banding of 

 the two forms. Coclilostyla schadenhergi schadenhergi comes from 

 Quiangan, in the mountain range which lies to the west of the one 

 from which our material was derived.

 Three specimens of this extremely rare and remarkable species 

 were in tlie sending received from Mr. Webb. The general coloration 

 of the shell is a pale green on the early whorls, deepening to dark 

 green on the last turn. A rather broad white spiral band encircles 

 the summit of the whorls and the base immediately below the peri- 

 pheral carina. The basal portion of the peripheral keel is so
