Length 0.60-1.15 mm.; breadth 0.40-0.55 mm.; thickness 0.35- 

 0.50 mm. * 



Original specimen in Paris, paratypes in Vienna. 



Guttulina austriaca has been often confused and mistaken by various 

 authors. It is generally considered to be identical with Guttulina 

 prohlema and G. communis. We do not deny its close relationship 

 to Guttulina problema, because it has the same arrangement of clavate 

 chambers, although in the present species each succeeding chamber 

 is removed from the proloculum, which is always very distinct in a 

 young specimen. In the plate are illustrated three phases of the 

 growth of Guttulina austriaca from specimens collected from the 

 original locality. The j^oungest is a specimen coinciding in every 

 respect with d'Orbigny's Guttulina austriaca, and the largest adult 

 specimen is nothing but the species described hj d'Orbigny under 

 the name Pohjmorphina oblonga (not of Roemer nor of Williamson).. 



Polymorphina guttula Reuss, a name given to the figures (pi. 30, 

 figs. 25-30) of Schlicht, having a botryoidal test, is closely related to 

 the present species.
