148 AMASTRA, KAUAI. 



brown, becoming yellowish-brown on the latter part of the 

 last whorl and around the umbilicus. Whorls 5%, weakly 

 convex. The spire is conic with concave outlines ; first half- 

 whorl smooth, with a pale tip, then faint radial ripples ap- 

 pear, this sculpture continuing for three whorls. The last 

 two whorls have sculpture of fine growth-striae and indistinct, 

 coarse, low wrinkles. Last whorl flattened above, convex be- 

 low the stout peripheral earina, which becomes subobsolete 

 near the aperture, which it does not modify in shape. Aper- 

 ture oblique, ovate, flesh-colored within, but thickened with 

 a white callus near the lip. Peristome obtuse, being a little 

 thickened within, the columellar margin expanded, generally 

 showing the end of a small spiral lamella which penetrates 

 about a half whorl inward. Internal axis regularly tapering 

 from below upward in each whorl, marked with low, pale, 

 obliquely axial striae or wrinkles (fig. 6).

Amastra cyclostoma BALDWIN, Proc. A. N. S. Phila., 1895, 

 p. 234, pi. 11, f. 53 (July 2, 1895). 



"Animal when extended in motion .95 inches in length; 

 posterior portion of foot tapering and very short, front por- 

 tion long; head elongated, ocular and labial tentacles widely 

 separated. Mantle dingy-white with streaks of black. Foot 

 very light brown, superior portion and sides thickly studded 

 with regular, dark brown granulations. Tentacles long, dark 

 brown" (Baldwin}. 



Respecting the locality of A. cyclostoma, Mr. C. M. Cooke 

 (in Hit. Apr. 11, 1899) writes: "Mr. Judd told me that the 

 locality of this shell is very restricted. It has been found in 

 only one place, under a few orange trees. A circle with 

 radius of six feet would enclose the whole space in which they 

 have been found. ' '
