252 LYROPUPA. 



Lyropupa mirabilis var. hawcwiensis ANCEY, Journal of 

 Malacology, xi, 1904, p. 68, pi. 5, f. 19. 



The above description is based on a specimen from the ori- 

 ginal material from which Ancey's type came, and may be 

 considered a paratype. It agrees with Ancey's type which 

 is slightly broken. 



This species is superficially close to L. mirabilis. It is here 

 considered distinct on account of the fewer costae on the last 

 whorl, the relative proportions of the lower palatal fold, which 

 is not interrupted, to the upper, and the presence of a basal 

 fold. The possession of this fold shows some relationship to 

 L. anceyana from which it is easily separated by its oblong, 

 less ovate form, the less convex whorls and more numerous 

 ribs on the last whorl. 



Ancey's description follows: "Separated from the type 

 (from the Waianae Mts., Oahu) as the shell is usually a little 

 larger, more robust, with pale costulas; with a stronger and 

 more elongate lower palatal lamelliform tooth ; whorls 6. 

 Length 2.5, diam. 1.25, apert. (long.) 0.75 mm. There are 

 twenty to twenty-two costulse on the last whorl, while in the 

 type specimen there are about twenty-two to twenty-four. ' ' 



According to our methods, Ancey's type specimens has the 

 following measurements: Length 2.45,_ diam. 1.35, apert. 

 0.85 mm.

The shell is subcylindric, with rather long terminal cone, 

 walnut brown or darker, with sculpture of rather short narrow 

 ribs, about 20 on the last whorl, intervals microscopically 

 granulose. There is a deep median sulcus on the last half 

 whorl. Aperture is somewhat triangular, with well-expanded, 

 pale, continuous peristome. The angular lamella is a low 

 ridge or reduced to a mere swelling. Parietal high but short. 

 The columellar lamella is short, thick, rounded, somewhat 

 transverse to the columella. The upper palatal fold is low 

 and not very long; lower palatal deeply placed, somewhat 

 stronger than the upper, and penetrates much further in; it 

 is usually a little curved. The basal fold is a low rounded 

 or oblong tubercle.
