The following are described, without figures, as new species : — Xeropltila 

 muttta, X. pumila, X. adina, X. horriditla. X. embryonata, Rlacitlaria leucochila, 

 Mast us liispalensis (all from Seville) : Torquilla refuga (Palermo), T. hoinala 

 (Sicily), T. retracta (Seville), Pitpilla honcsta (Italy) ; Fentssacia virginea 

 (Seville), Circilianella gattoi, C. melitensis, C. pol/onei\c (all from Malta); Bulimts 

 clathratiis (Seville), l'oinatias eircticus (Sicily), Xeritina mixta (Seville), and 

 a number of new varieties, which we refrain from transcribing. What useful 

 purpose is attained by the publication of these so-called new species, we are at 

 a loss to imagine. Nothing is better calculated to degrade the true interest of the 

 science, and to heap up difficulties for those whose task it will be in future years 

 to consign these fanciful creations to the obscurity they deserve. — A. H. C.
