 From Santa-Cruz de la Sierra, Bolivia. Originally described 

 from the Yungas. 



Bulimulus fusoides D'Orb. 



This is a species peculiar to Bolivia. The specimens 

 obtained from Santa Cruz de la Sierra are yellowish-ochraceous 

 and are provided with more or less distinct and numerous 

 obscure strips, which in some individuals are absent or very 

 faint. The colour of aperture is characteristic. Some specimens 

 are more slender than others. This species is not found in 

 Ecuador, the specimens from that state I received under this 

 name not belonging to it.
