108 COLUMBELLA. 



mercatoria, but is probably a synonym of rustica. I suppose 

 that C. xiphitella, Duclos (fig. 55) r and C. xiphitella, Reeve (fig. 

 56), may both be placed here, although the}^ are very different 

 shells in form. 



C. ANACTEOLA, Duclos. PI. 44, fig. 58. 



Shell smooth, the lower) part with revolving striae ; color 

 chocolate-brown varied with white, somewhat longitudinally 



disposed. Length, I'l inches. 



Habit a t un known . 



This species has not been described ; there are only the figures 

 and name in Duclos' monograph. It resembles the stouter, short 

 forms of C. rustica, somewhat, but is a larger shell. 



C. MARMOREA, Brasilia. 



Shell small, ovately subturbinate, smooth, shining, with 

 flattened whorls ; aperture dilated at the base, sublinear, longer 

 than the spire; lip but little thickened within, nodulose; colu- 

 mella with two tubercles; color marbled with fulvous and white, 

 with a white, maculated -band at the suture. 



L. 10, diam. 5 mill. 



Ddlinatut. 



An unfigured species, related to C. rustica, and possibly a 

 young individual of that protean species. 



C. PARDALTNA, Lam. PI. 44, figs. 59-74; PI. 45, fig. 75. 



Shell oval, smooth, with moderate, somewhat convex spire; 

 white, tessellated or longitudinally flexuosely striped with chest- 

 nut or chocolate, with frequently a white band, similarly tessel- 

 lated at the suture. Length, '75-1 inch.

The synonyms are: C.vulpecula, Sowb. (fig. 61); C. quintilia, 

 Duclos (figs. 62, 63); C. fabula, Sowb. (fig. 64); C. Ja/ton'ica, 

 Reeve (fig. 65); G. zopilla, Duclos (fig. 66). 



Var. TYLERI, Gray. PI. 44, figs. 67-74; PI. 45, fig. 75. 



Only differs by having a more produced spire, and is readily 

 united with the typical form by sucli synonyms as G. sagena., 

 Reeve (fig. 69 , Japan. Other longer forms are G. obscura, Sowb. 

 (fig. 70) ; G. palmerina, Duclos (fig. 71) ; C. lactescens, Souv. (fig.
