Santa Cruz de la Sierra (Germain). 



This Conulus-shaped shell, I refer with some reluctance to 



the above genus, not having examined its soft parts, but as it is 



allied to Guppya gmidlachi Pfr., and has the spiral sculpture 



of the latter, I suppose they are congeneric. The present 



species is remarkable on account of the 7'ery fine strife of the 



upper surface, giving it a peculiar silky appearance, the lower 



portion being in that respect like that of our P'.uropean Couulus 



fulvus. 



Systrophia alcidiana Anc, n. sp. 

 This new species, found at Corumba, Matto-Grosso, is very 

 near to S. chielostropha D'Orb., a Bolivian shell, but is smaller 

 (diam. 6i, alt. 2| mill), has only fine regular crowded stride 

 {iioi ribs) above, less sinuous aperture, the teeth on the lip 

 being very small and possesses only six volutions at most, not 

 6A-7. The colour in the only specimen observed is white. 



Bulimulus germaini Anc, n. sp.

 guratis picta. Spira mediocriter producta, obtusiuscula. 

 Anfradus 6J convexi, sutura pariim profunda discreti, 

 vltimus attenuatus, oblongus, ad aperturaia breviter subitoque 

 ascendens. Apertura paulo obliqua, oblonga, vix huiata, 

 superne augulata, patula, intus cum parietc et columella
