HELIX-PAPUINA. 73 



(12) GROUP OF H. FRINGILLA. 



Imperforate, globose-trochoidal, solid, the spire rounded ; surface 

 striatulate ; lip reflexed, columella bearing an obtuse fold, as in the 

 group of H. lienardiana. 



H. FRINGILLA Pfeiflfer. PI. 16, fig. 8 ; vol. VI, pi. 49, figs. 20, 21, 



22, 23, 24, 25. 



Imperforate, solid, depressed-globose, the spire dome-shaped or 

 convexly low-conical ; apex obtuse ; whorls 4, slightly convex, the 

 last whorl subcarinated at the periphery, abruptly deflexed in front, 

 strongly constricted behind the peristome, which is narrowly reflexed, 

 white or bright pink; surface smooth, shining, lightly striatulate. 

 Color olive-yellow, either unicolored or having brown spiral bands ; 

 inner whorls white or pink. Aperture oblique, subquadrate, white 

 within ; columellar margin straight, sloping, having a more or less 

 distinct fold-like callus, or blunt tooth, on its inner margin, near the 

 insertion.

Differs from other species of Papuina in the con vex outlines of the 

 spire, the constriction behind the lip, and the subdentate columella. 

 It varies much in color-pattern. Some specimens are pure white, 

 the lip either white or rose-color. 



H. BARNACLEI Smith. Unfigured. 



Shell imperforate in the adult state, (narrowly umbilicated when 

 immature and acutely angled at the periphery) conoidly globose, 

 with a very shining surface, of a rich fulvous or deep fawn color, the 

 upper whorls become gradually paler than the last, and toward the 

 apex are semitransparent horn color and encircled by a single nar- 

 row dark brown line just above the suture, which is white; this line 

 becomes much broader upon the body whorl, which has a second 

 similar band beneath the more or less white periphery ; this is
