The T. gausapata, was described by Brown and Pilsbry, 

 from young specimens, measuring only 19 mm in length. Later 

 in the same year appeared Toula' s T. acuaria, also based on 

 young shells. 



The important characters of this species, are its nearly 

 straight ribs, deep sulcus, a sutural band with faint spirals 

 and even sculpture. Figures 23 and 24 of Cossmann I believe 

 represents wolfgangi. T. ivolfgangi as will be noted from the 

 accompan3dng figures is a much more slender species and usually 

 with a smooth sutural band. The pillar carries two broad folds, 

 which are better developed than in ivolfgangi ox gatuneiisis. 



Length 33, breadth 8.5 mm.
