More strongly striate than its allies. Hidalgo unites B. pintadi- 

 niis Orb. to floccosu.3, considering it the adult form. The specimens 

 before me are apparently adult, and are of the form shown in figs. 

 86, 88. 



P. PINTADIXUS d'Orbigny. PI. 36, figs. 84, 85. 



Shell oblong, ventricose, thin, substriate, brownish-violaceous, or- 

 namented with reddish-brown and whitish spots. Spire conic, apex 

 acuminate, obtuse. Whorls 5, the last oblique, large. Aperture 

 oval, brown-violaceous ; columella thick ; lip somewhat thick, sub- 

 reflexed. Length 60, diam. 30 mill. (Orb.). 



Humid and luxuriant forest country of the Yuracares, at the foot 

 of the eastern cordillera of Bolivia (Orb).

Described from one dead specimen, deposited in the collection of 

 the Museum of Natural History of Paris. The colors are somewhat 

 faded, but it seems to be of a brown-violet tint, darker on the last 

 whorl, which is ornamented with a few small transverse spots of 

 dark brown violet, each with a transverse white spot on its left side, 

 so that the dark spots seem like the shadows of the light ones. It is 

 shorter and more ventricose than B. floccosu$, and, judging from 

 Orbigny's figures, there seems to be an umbilical chink behind the 

 columellar lip. 



P. ONCA d'Orbigny. PL 37, figs. 89, 90, 91. 



Shell imperforate, elongated, rather thin, striatulate, diaphanous ; 

 tawny, with irregularly scattered chestnut spots. Spire conic, the 

 apex obtuse. Whorls 5, the last hardly longer than spire. Colu- 

 mella scarcely folded, obliquely receding, roseate. Aperture ob- 

 long-oval, flesh-colored inside ; peristome narrowly expanded, its 

 ends joined by a thin rosy callus. Alt. 58, diam. 22 mill. ; aperture 

 31 mill, long, 13 wide. (Pfr.~). 



Tutulima, northeastern part of eastern cordillera of Bolivia in deep 

 humid ravines (Orb.).
